  1. Dear Insights, in question no 4,Mangroves are highly adapted to salinity…then how will increase in salinity is a threat to mangrove?.(.in statement no 3) can u explain?…explanation given states that statement 2 is correct..but answer depicts the statement as wrong..please explain?

    1. Mangroves grow in saline waters, but there is a limit to tolerance of salinity in Mangroves. If salinity exceeds the tolerable limits, it adversely affects Mangroves. You can take an analogy of high rainfall and soil fertility: more is good, but too much of rainfall leaches the soil.

      The given answer and explanation are correct. 🙂

      1. Sir . but global warming is supposed to reduce salinity of ocean correct ? Due to addition of freshwater from arctic.
        So then won’t that option become wrong ?

        1. same logic i applied man. Got answer wrong. The sources i use says addition of fresh water decreases salinity and no addition plus evaporation lead to increase salinity. Ice berge are made of fresh water to melting of them will add considerable amount of fresh water to oceans

        2. Global warming is increasing evaporation over oceans, reducing rainfall and drying freshwater rivers. The pattern can be very clearly seen in tropical and sub-tropical regions that is leading to increasing salinity in these regions.

          The moisture (and rainfall) is being driven to the higher latitudes. Along with melting glaciers, higher latitudes are seeing less saline waters.

          But, Mangroves are least likely to be found at higher latitudes (where the ocean waters are becoming less saline). They are concentrated more in the region around tropics where oceans are getting saltier; hence, the threat. 🙂

          1. //The moisture (and rainfall) is being driven to the higher latitudes//
            Sir, does this mean that sea level is not rising in tropical and sub tropical region?

          2. Just a request sir, can you please few questions on Deen Dayal Upadhyaya and Shyam Prasad Mukherjee either in daily tests or in upcoming test TA.

            1. We had done it in the last year Test Series. But, they are highly politicised figures, so not very important. 🙂

              1. Sir I thought because NDA Led Govt is using there name in each and every major initiative/scheme so thought there may be questions anyways will stick to your point thanks:)

          3. Hi Insights !
            is there any list of important tribes of India or some reliable source with short (3-4 line description). I have googled it, but didn’t find any. The ones found are either inadequate or too exhaustive. Please help !

            1. This is the most exhaustive list, but there is no description available. You can make short notes from our tests and consolidate them quickly. We have covered many of them. 🙂

              1. “This is the most exhaustive list” – I guess you missed mentioning the link ! Please copy-paste the link once again, as I am unable to see any link in your comment. Thank you 🙂

    1. Yes, that is correct. We will amend the question statement slightly to remove the word “only”. Thank you for informing.

      1. Hi.. I am new to Insightsonindia site. I would like to subscribe for the prelims test series.. I know its already late.. But still i have two months, so thought of practicing them.. I have been trying to contact support since four days and they are not responding to emails. I dont know why and they did not even mention any contact number in the website.
        My simple question is, after completing the test online from the dashboard, will i get a pdf with answers and explanations or not? how and when will i get the explanations after completing the test.
        I hope i will get a reply atleast here from insights staff

        1. Srinivas, yes you will be able to locate a PDF (with solutions and explanations) in your test account dashboard once you complete the test. 🙂

          1. q-52 test 21: according to NIOS, Puranas contain information about “dynastic genealogies”.so as per it the answer should be D rather than B. plz clarify.
            q-54 test 21: your explanation says north nicobar do not have a deciduous forest nor evergreen forest…then what type of vegetation is found there?
            q-59:regarding aerosol particles…….u explained that CFC’s have been phased out but my doubt is how will we consider such statements(its too subjective).like some may say cfc’s used to deplete so answer shud be correct.plz clarify

          2. i have attempted only 7 tests(2nd test to 8th test). remaining all tests are not opening. they r showing that u have already taken the test. IN TEST HISTORY clearly it is showing that I HAVE ATTEMPTED only 7.

          3. Hi @insightsprelimstestseries:disqus , wrt Q32, can we say the Const has defined scheduled tribes ?

            1. No. Constitution only defines the general term “minority” and leaves the rest for the Parliament to decide.

      4. ur response during initial days of the test series was really good but now its totally worst…….i have been asking questions from last 12 days repeatedly but there is no response from ur side……….for a doubt to be clarified we cant wait for so many days…..this post now doesnt mean that u were replying well before 1 month or so…..this post now is bcoz exam is too close now………and yes u r forcing us to revise the wrong answers given in ur pdf of the tests……u shud understand how important it is and from last 3 months u have been ensuring us about corrigendum but no progress in it too….its high time u shud consider the above comment…..plz atleast reply to it

        1. Hello Pink Panther
          Yes this is most crucial time for all of us and even a slight mistake will get us out of the race.
          But there are always 2 ways of saying the same thing you used one but not other.
          Your concerns are valid and I hope Insights Team should reply to you ASAP.
          Hope this is Ok and if you think other wise, you are very welcome.

      5. Sir Please clarify how Polar Vortex is low Pressure System, This is associated with Q22 in this test.
        Thanks

        1. Polar vortex, even though very cold, has lower pressure than the surroundings perhaps because of its high altitude (up in the lower/middle stratosphere), or the cyclonic type circulation. We are not sure what is it exactly, as it is more an area of scientific pursuit.

          But, as far as its effects are concerned, it keeps the regions near pole very cold. As a generalist, this is the single most important fact that we should be interested in. Thank you.

      6. Sir, in Q.29:
        Is not the statement “Consolidation of power of East India Company in Bengal” more suitable for the Battle of Buxar?
        3rd Battle of Panipat only “gave an opportunity to the English to consolidate its power in Bengal and South India.” As also mentioned in your explanations.
        Should it be considered a consequence?
        The answer should then be “D. None”

      7. Sir, in Q.96:
        Regarding the Statement 2: “English had no responsibility for the internal administration.”
        I quote Modern India (NCERT, Old Edition. Chapter 2: European Penetration):
        “..The Nawab was to administer Bengal through a Deputy Subahdar, who was to be nominated y the Company… thus gained supreme control over the administration (or nizamat) of Bengal.”

        While this does not mean that the English could be held responsible for administration, wouldn’t this make the statement 2 (‘no responsibility’) false? I’m considering appointing a Subahdar and thus controlling the administration as a “responsibility” (not from the people’s but the Company’s perspective).
        Could you please clarify?

        1. If this argument were true then one could also say that as the Nawab was also selected by the Company, so the company was responsible for the whole administration of Bengal and there was no dual system. But this is not how administrative responsibility is to be understood. Administrative responsibility would mean who dealt with those matters on daily basis. Surely it was not the Company. On day to day basis, the company only dealt with the revenue matters.

          1. Point understood.
            I got confused by the “no responsibility” phrase. Thank You very much for clarifying.

        2. No Dear, the English were not to be held responsible for internal administration, which was the domain of the Nawab. The English only exercised Diwani rights. Their interference in appointment was informal political in nature. This way they could exercise greater control over the administration, without any responsibility ! 🙂

  2. Dear insights team I’m follower our test my average score is ~75 in whole test I can’t improve above

        3. For Question 53: The first statement: “Securing the economy against global liquidity shock”

          Full capital account convertibility would be beneficial in this case as it allows India to print more currency and meet any global liquidity shock.
          Can you please clarify 🙂

          1. Capital account convertibility is not at all related with printing currency notes. Please revisit the concept explained in the PDF. It is about allowing freedom of converting rupee into foreign exchange and vice versa for capital transactions.

            Also, liquidity shock is dealt by RBI through sterilization by open market operations i.e. buying and selling bonds to the public to reduce liquidity present in the economy.

            1. Thanks for the prompt reply team. Really appreciate your efforts 🙂
              What i was referring to was the fact that once our currency is made convertible – it would enjoy value and global acceptance in territories outside India. Like Indians can make purchases, investments outside India directly using INR. Using this logic – i thought that any global liquidity shock can be managed locally (by India) by printing currency which would have global acceptance (Once it is made convertible)

              I may be wrong.

        4. @insightsprelimstestseries:disqus Q61 says DTAA impacts only FDI. But capital gains tax will have to be paid by an FPI on FII as well. Plz explain.

    2. It’s Ok to score this much as Tests are intentionally designed a bit tough. It’s always better if you evaluate your performance from full-length tests (Test 24 onwards).

      Also, many questions from the Test series will be found in UPSC Prelims exam. So please do not worry about the scores much and focus on absorbing as much knowledge as you can.

      Once you have revised the entire syllabus and able to score around 95-100 in the full-length tests, you will fare very well in the final exam.

      All the best! 🙂

    1. All central taxes form part of divisible pool of taxes excluding surcharges and cess.

      Some taxes directly form part of State’s revenue (e.g. Agricultural land stamp duty), and others are devolved by the Centre to the states once the centre appropriates it (e.g. Corporate tax).

      Such an arrangement is made to ensure more efficient tax collection and reducing legal ambiguities in tax collection.

      1. In explanation of Q.46, you have mentioned—-no part of the proceeds of these taxes can be assigned to the states.

        1. We should have added the word “assigned/appropriated directly” to avoid confusion.

  3. Q.68
    Not clear with meaning of regressive expenditure. Wouldn’t it be like reducing expenditure with increasing economic class?
    Progressive expenditure would help the well of only as expenditure would increase with increasing economic class. Wouldn’t it?
    Deduced this understanding because in progressive taxation, tax increases with increasing economic class.
    Please clarify.

    1. Dear, please stick to the definition as explained in the PDF. The term “progressive” expenditure doesn’t connote expenditure rising in progression from poor to the rich, it connotes an expenditure that is redistributive in nature. 🙂

  4. doing insight prelim test series of previous year that is 2015 and 2014 is worthwhile or not .confused

    1. 2015 papers are certainly more important than 2014 papers. If you don’t have enough time, only 2016 + 2015 will do. If time is a luxury, 2016 papers alone will suffice. 🙂

  5. Good morning dear co aspirants..
    I have paid the payment for prelims test series on 23 may 2016 n received the payment id but not id n password from insight on india hence I m unable2 write the test series .I m leaving mail to insight supportteam everyday but no response from them..what hell is this what should I do now whom should I contact to get an id n password?can anyone suggest me in this regard?

    1. Dear, if the payment was successful, you will be immediately directed to the Test dashboard, and can take the tests from then onwards.

      We do not send individual ID and passwords via e-mail. Please once confirm the payment with support@instamojo.com. If it was unsuccessful, the amount would have been refunded to your account. You will need to subscribe again. Thank you. 🙂

      1. Thank you for your reply sir I got Payment id from support@instamojo.com..I got confirmation mail from ur sight too but when I tried to access the test series I was asked to enter an id n password for which I m asking you now…kindly suggest me I have forwarded the copy of payment id to ur mail…kindly resolve my issue as soon as possible..Thank you

  10. sir the problem is not resolved yet, i am unable to download test at test history plz debug it.

      1. Website says “(HFC) contributes to ozone depletion by a small but measurable amount”. Its a new finding.
        Old articles of Mrunal says HFCs are not Ozone depleting but a Green House Gas.
        So in think Insights has used old data.

        1. Yes it’s a new finding. That’s why i have asked Insights to clarify so that they can correct it in their corrigendum if they find it valid. 🙂

  11. Dear Insights Team, Kindly clarify what you mean when you write IMPROVISATION after Source in your test answers.

  14. Dear insights team
    Regarding q 100.Will you please clarify, how does algae purify wastewater???? . I’m not able to comprehend Explanation given by you.

    1. Algae => Photosyntheis = takes CO2 and releases O2 in water. BOD(Biochemical oxygen demand) decreases. And when BOD decreases, process of breaking down of dead organic things in water accelerates.

  15. Dear sir, @Insights Prelims Test Series while attempting from Test 1, still finding the some options mistakes in Qs and As. Please update them. Thank you

    1. Please see the corrigendum posted on Test 24 Discussion page. Thank you.

  16. @insightsprelimstestseries:disqus q-52 test 21: according to NIOS, Puranas contain information about “dynastic genealogies”.so as per it the answer should be D rather than B. plz clarify.
    q-54 test 21: your explanation says north nicobar do not have a deciduous forest nor evergreen forest…then what type of vegetation is found there?
    q-59:regarding aerosol particles…….u explained that CFC’s have been phased out but my doubt is how will we consider such statements(its too subjective).like some may say cfc’s used to deplete so answer shud be correct.plz clarify

    1. 21. The answer given is correct. The primary purpose behind writing Puranas was to expound the truth given in Vedas. The genealogy of Kingdoms followed as a secondary consequence. Moreover, the genealogy given in Puranas is not absolutely reliable and must be read with caution.

      54. Mangroves and Grasslands may be found.

      59. Such questions will be rare and at times there may be confusion. UPSC may not ask such questions. You should go by the most recent developments. Please stick to the answer here.

      1. test 23:-
        q-99 option b: says high level of govt borrowing but govt is committed to fiscal consolidation and reducing its deficits,so it must be reducing the borrowing too….plz clarify
        q-89: your explanation says the act opened civil service examination to indian also but actually it was opened through charter act of 1853 though it was recommended in 1833 it was negated after opposition from court of directors…plz clarify
        q-17 the equilibrium market price of good is determined by marginal cost and revenue. plz can u explain the conditions where it is determined by (i) buyers and (ii) total capital output
        q-7 are popular sovereignty and republic the same?

        1. 99. Yes, the government is reducing borrowing. But, the level of fiscal deficit still remains high over 4.5% of GDP. Moreover, as the government borrows a huge amount via the SLR mode from banks, it gives less space for banks to earn profits (SLR yield rate is fixed). So, the scope to reduce interest rates following an easing of monetary policy is difficult for banks.

          89. Yes, it was only a proposal which was later negated. It was only in 1853 Act that the provisions actually came in force.

          17. The Marginal revenue curve is actually similar to the market demand curve that shows buyer’s preferences. Marginal cost curve is also affected by the quantum of output and amount of capital used in the process. It is not possible to explain here in detail. Please see the 12th Microeconomics book in this regard. There is no need to go in detail.

          Q7. They are different things. Both UK and India have popular sovereignty, i.e. elected governments where people are the ultimate decision makers. In a republic, the head of the state is elected. UK is not a republic where the head of state is hereditary.

          1. SLR is maintained by bank in their own vault not with RBI. So RBI cannot lend anything from SLR to government.

            secondly SLR can be maintained in cash,gold or government security/RBI approved security. Though bank mostly maintain SLR in form of g.sec (and thus we can say gov borrow thru SLR) but its not binding or any quota that certain portion should be maintained in only g.sec. So statement that SLR is means for government borrowing is not completely correct (what if bank decide to maintain all SLR in GOLD)

          2. Q89 trading monopolies of company were discontinued. Its licence for trade was further renewed for 20 years. So if i am right option 2 must be wrong too? @insightsprelimstestseries:disqus

            1. The charter was renewed for another 20 years, but it ended the activities of the company as a commercial body and it was made a purely administrative body. 🙂

  17. @insightsprelimstestseries:disqus Sir, what is full scope safeguards w.r.t NSG/NPT?

    1. We are pasting from this link, you may also read it here
      http://www.world-nuclear.org/information-library/safety-and-security/non-proliferation/safeguards-to-prevent-nuclear-proliferation.aspx

      The aim of traditional IAEA safeguards is to deter the diversion of nuclear material from peaceful use by maximising the risk of early detection.

      The inspections act as an alert system providing a warning of the possible diversion of nuclear material from peaceful activities. The system relies on;

      1. Material Accountability – tracking all inward and outward transfers and the flow of materials in any nuclear facility. This includes sampling and analysis of nuclear material, on-site inspections, review and verification of operating records.
      2. Physical Security – restricting access to nuclear materials at the site of use.
      3. Containment and Surveillance – use of seals, automatic cameras and other instruments to detect unreported movement or tampering with nuclear materials, as well as spot checks on-site.

      All NPT non-weapons states must accept these ‘full-scope’ safeguards, which apply to all nuclear facilities in the country. In the five weapons states plus the non-NPT states (India, Pakistan and Israel), facility-specific safeguards apply to relevant plants (see further section below). IAEA inspectors regularly visit these facilities to verify completeness and accuracy of records.

  18. This is regarding question no.72 from test 1…in the explanation its been given that primary health centre serves a population of 3,000-5,000 and community health centre serves 15,000- 20,000…this is incorrect…each PHC caters to a population of 20,000 in hilly areas and 30,000 in other regions of india…and 4 PHCs are included under each CHC thus catering to approximately 80,000 populations in tribal/hilly/desert areas and 1,20,000 population for plain areas….below is an old document…but guidelines have not been changed

  19. hello ,
    q3 – http://pib.nic.in/newsite/Prin

    TEST 21

    The Minister of Culture Smt. Chandresh Kumari Katoch in a written reply in the Rajya Sabha today has said that the criteria evolved by Government to determine declaration of a language as a Classical language is as under:-

    (i) High antiquity of its early texts/recorded history over a period of 1500-2000 years;
    (ii) A body of ancient literature/texts, which is considered a valuable heritage by generations of speakers;
    (iii) The literary tradition be original and not borrowed from another speech community;
    (iv) The classical language and literature being distinct from modern, there may also be a discontinuity between the classical language and its later forms or its offshoots.

    Why have you not specified last one in “Justification and learning “?

    q 37

    From your own daily current affairs 12th may : The court said the regulation which fastens strict liability on the telecom companies for no fault of theirs is arbitrary and violative of Article 14 of the Constitution.

    so it should have been both option C n D

    1. 37. Yes Dear, the answer will be both option (c) and (d). We had addressed it in the comments below also.

      1. what about q3 ? what if i come across a question which i don’t have a idea about and follow only your explanations and it turns out be wrong or half correct ?

  20. i have attempted only 7 tests(2nd test to 8th test). remaining all tests are not opening. they r showing that u have already taken the test. IN TEST HISTORY clearly it is showing that I HAVE ATTEMPTED only 7.
    pl solve the problem as soon as soon possible. i want to complete my tests
    when i click on take test it considers an attempt and not allowing to take test without opening the test page… resove it soon

  21. Q 73 (Test 23) I went through the India 2016 book ( Q. source), nowhere is it mentioned that PMKVY would essentially target dropouts from class 10 and 12. Hence, shouldn’t the answer be “A” rather than “D”

  22. @insightsprelimstestseries:disqus : ur response during initial days of the test series was really good but now its totally worst…….i have been asking questions from last 12 days repeatedly but there is no response from ur side……….for a doubt to be clarified we cant wait for so many days…..this post now doesnt mean that u were replying well before 1 month or so…..this post now is bcoz exam is too close now………and yes u r forcing us to revise the wrong answers given in ur pdf of the tests……u shud understand how important it is and from last 3 months u have been ensuring us about corrigendum but no progress in it too….its high time u shud consider the above comment…..plz atleast reply to it

  23. Hello Sir, Qn: 53, //:Capital account convertibility means the freedom to convert rupees into foreign currency and back for capital transactions//. But as per Ramesh Singh, capital acc convertibility mean freedom to convert rupee to dollar only, not freedom to convert back (dollar to rupee). Pls clarify.

      1. Thanks for your reply sir. thats cleared.
        I have another query regarding q4.

        Your explanation:
        “Global warming is increasing evaporation over oceans, reducing rainfall and drying freshwater rivers. The pattern can be very clearly seen in tropical and sub-tropical regions that is leading to increasing salinity in these regions.

        The moisture (and rainfall) is being driven to the higher latitudes. Along with melting glaciers, higher latitudes are seeing less saline waters.

        But, Mangroves are least likely to be found at higher latitudes (where the ocean waters are becoming less saline). They are concentrated more in the region around tropics where oceans are getting saltier; hence, the threat. :-)”

        //The moisture (and rainfall) is being driven to the higher latitudes//
        Sir, does this mean that sea level is not rising in tropical and sub tropical region?

          1. Hi varma,

            3rd point, even i’m not convinced. I have asked about that to @insightsprelimstestseries:disqus above. Hopefully sir reply will reply very soon.

            2nd point is clear. With rise in temp, corals will get destroyed. So wave actions on shore will increase. But the statement says the reverse, so that statement is wrong.

            1. Hi VM
              if you have time pls clear one doubt…
              in Test 23, Q4:
              about Statement 2: Wave action that sustains the nutrient flow to mangroves will be reduced drastically.

              how could we co-relate this with coral reef, as a general fact there is no coral reef if we move from mangroves towards ocean, as coral reefs grow in shallow waters while mangroves grow in relatively deep waters.
              Though that is true that wave action will increase due to which statement 2 becomes wrong but how this could be related with reefs. can you throw some light?

        1. Oceans are connected to each other. Greater precipitation at the higher latitudes increase the sea level not only at the higher latitudes but also at the lower latitudes, i.e. tropical and sub-tropical regions.

          1. Thanx for your quick reponse sir..
            but still confused.
            my doubt is how salinity is increasing in tropical ocean region?
            Evauparation is high in tropical region: AGREED
            Though the humidity and rainfall is carried away towards higher latitudes – since oceans are interconnected – it rises water level of tropic region aswell.
            So the excess water flow from the higher latitude should nutralize the increasing salinity(due to evauporation) of tropical region.
            I actually believe the fresh water formed due to melting of glaciers, and their resultant flow towards tropics, should actually reduce the salinity of tropics aswell as whole ocean.
            Pls clarify why you are saying salinity of tropical ocean will increase with global warming.

            1. Dear, the oceans are not a small bowl of water, where mixing of ocean water is so easy. If you just consider the vast magnitude of oceans, you will realize how difficult is the mixing of water. Even at the same location, salinity differs from layer to layer at various depths. So, the fresh water formed due to melting of glaciers will only increase the ocean level, and not cause homogenous mixing of ocean salinity.

  24. @INSIGHTS
    I am not doing answer practice properly….I write answers rarely and I make notes sometimes.
    should I start writing answers regularly after prelims?or any other solution to my problem?I think I will face problem in Mains exam….plz reply and provide me a practical solution…

  25. q48: insight,corporate tax under tax devolution of FINANCE COMMISSION.IT not wholly appropriated by centre?and custom duites also.

    1. It is appropriated by the Centre initially, but after the tax devolution suggested by the Finance Commission, it becomes a part of the divisible pool, and thus shared with states later. 🙂

      1. Q4: insight,can you explain 2nd and 3rd statement in 4th question regarding mangroves?how salinity poses threat to mangroves?The relation between coral reefs and mangroves?

  26. In q8 , shouldn’t a sulprus budget be given to an economy suffering from economic depression?Countries like Japan or PIGS give more money to stimulate the economy to come out of economic depression?

    1. A surplus budget means the government is not spending all it has. It is still left with surplus revenue. This is exactly opposite to what a depression-like situation requires. We need more government spending to boost the economy in depression, and this requires a deficit budget (where government borrows to finance more expenditure).

    1. When rich gain more from the government expenditure than the poor, or when the government spends more on the welfare of the rich than that of the poor, it results in even more inequalities. This is what we call as regressive expenditure. 🙂

  27. Muslim league also attended round-table conferences.? Was not anybody other than Ambedkar attending all three?

    1. People other than Ambedkar also attended the conference, like Mr. Sapru. The answer requires a correction, and we will update this in the corrigendum. Thank you.

  28. Q65 Why cant answer be Option D ?

    Q 95 HFC’s are covered under Kyoto Protocol so answer can be B

    1. it is covered under kyoto.Thats why 3rd statement is incorrect.so option cant be the answer.

  29. Q 43)The second option-“No appeal will lie to any court in India from the decisions of the special court”
    what does this mean ?Is it saying that there no further appeal to other court after a decision of arbitration court.
    What is the rule?

      1. It means after the arbitration (special) court has ruled, the case cannot be taken to higher courts for further adjudication.

        The statement is clearly wrong because:
        1. Arbitration doesn’t happen in a court
        2. Further appeal lies with respect to an arbitration if the parties decide

    1. It means after the arbitration (special) court has ruled, the case cannot be taken to higher courts for further adjudication.

  31. Q44. Statement 3. It will help the stateless citizens living in former enclaves by granting the citizenship
    from their respective countries.

    people living in those enclave were not stateless. they were citizen of their respective country, though surrounded by foreign territory.
    might be my understanding of “stateless citizen” is wrong
    sir please explain?

    1. Even my understanding is that people living in enclaves are not stateless. @insight kindly reply

  32. Q55. Option D. Private property

    sir does not “private property” also mean any type of private belonging like house, car etc…
    i think correct option would have been “Private means of Production”
    please comment

    1. It was both private property and private means of production. The latter is considered as a part of the former. For e.g. an entrepreneur may own land, and decide to start production through it.

  33. Qu: 89 Trade activity of East India company was abolished in charter act 1813 not in 1833.
    Kindly confirm this fact.

    1. It was only during Charter Act of 1833 that East India Company was made a purely administrative body, with no commercial interests.

  34. i just gave my 26th test series , total question which i attempted is 79 , right 52 , wrong 27 , left 21 , marks = 86 , (but i am not able to score more than 86 , in my all exam my marks are between 55 to 90 , is that means my marks in UPSC prelims will going to be the same just as which i am scoring here in this test series ? pls reply me ASAP

    1. always keep these few things in mind:focus on your weak point regarding each test,see why you were wrong in a particular question and also why you are right for the question(sometime happen you mistakenly or arbitrarily marked an answer),take at least 5-6 hours for holistically covering the test with solution and related articles.lastly don’t loose hope,you marks are not bad though.just try to score more.

  35. Hi @insightsprelimstestseries – is there any list of important tribes of India or some reliable source with short (3-4 line description). I have googled it, but didn’t find any. The ones found are either inadequate or too exhaustive. Please help !

  36. question 71 : mughal paintings reached zenith under ….answer

  38. Dear insights,

    Can we give the last two tests in first week of august. Before 7th august offcourse!

    It’s
    written on site that tests are available until july, but due to my
    personal schedule and to maintain momentum, i would like to give atleast
    the last two tests on 3rd n 4th of august.

    Will the site be live then? Please confirm

    Thanks in advance

  39. Clarifications for Test 23

    4. The given answer and explanation are correct. Mangroves grow in saline waters, but there is a limit to tolerance of salinity in Mangroves. If salinity exceeds the tolerable limits, it adversely affects Mangroves. You can take an analogy of high rainfall and soil fertility: more is good, but too much of rainfall leaches the soil.

    11. Answer will be option (a). Statement 2 is incorrect. Along with B.R. Ambedkar, M.R. Jayakar and T.B. Sapru also participated in all Round table conferences.

    46. All central taxes form part of divisible pool of taxes excluding surcharges and cess. Some taxes directly form part of State’s revenue (e.g. Agricultural land stamp duty), and others are devolved by the Centre to the states once the centre appropriates it (e.g. Corporate tax). Such an arrangement is made to ensure more efficient tax collection and reducing legal ambiguities in tax collection.

    94. A recent NASA study suggests that HFCs may harm ozone layer. They have disproved a long-held assumption which was also the basis of including HFC in many international climate change negotiations.
    http://www.nasa.gov/press-release/goddard/nasa-study-shows-that-common-coolants-contribute-to-ozone-depletion

    We are not sure if UPSC will notice this new research, since we have observed they sometimes rely on old and outdated sources.

    Thank you.

    1. Question 4 Explaination says statement 3 is incorrect. My understanding is C should be the correct answer. Wave action and salinity is correct, right?

      1. We have addressed it in the Corrigendum (Test 21-30) clarifications. It will be uploaded by today. Thank you.

        1. You guys have a wonderful team and I appreciate the hard work you guys put in your efforts and especially the way you handle test series. Commendable job! Wish I had put the same level of effort in my prep too:D
          Anyways Cheers to Team at Insight.??

  40. Question 49 :

    Primary pollutant of automobile exhaust is CO2 rather than CO

    pls correct me if I am wrong.

      1. so u mean to say all these are primary pollutant??

        Particulate matter (PM). These particles of soot and metals give smog its murky color. …
        Hydrocarbons (HC). …
        Nitrogen oxides (NOx). …
        Carbon monoxide (CO). …
        Sulfur dioxide (SO2). …
        Hazardous air pollutants (toxics). …
        Greenhouse gases.

        1. Yes, CO2 is generally not considered a primary pollutant. It is by itself not so harmful as the primary pollutants. It is the high level of CO2 which can be harmful, in the form of a greenhouse gas contributing to global warming or when it cuts the supply of oxygen for our breathing. Otherwise, CO2 is an essential gas, especially for the respiration of plants (so necessary for our ecosystem).

          And the above ones are primary pollutants. Primary pollutants are named so just to differentiate them from secondary pollutants. Primary pollutants are those that occur directly from the source, i.e., they are by themselves pollutants and not because of their constituents. Like Nitrogen Oxides are pollutants, but nitrogen and oxygen that constitute them are not pollutants. Secondary pollutants, on the other hand, are those that are formed by combinations of primary pollutants. Like, the ozone, which is formed by photo-chemical reaction of nitrogen oxides and hydrocarbons.

  41. Third battle of panipat’s implication only restricted to bengal consolidation??

    pls confirm

  42. how can we say DTAA will have impact on FDI only??

    as far as i have read about DTAA it has provision w.r.t. FII as well.

    or u mean to say that it mainly affects FDI and rest are less affected??
