  1. this year after prelims in many questions many students debated about answers which are ambiguous , so can any one of you help me in this . i mean what we should mark , what is given in NCERT or what is correct . this dilemma is mainly in science and geography .
    for eg : in NCERT in decomposers they even used scavengers eg. so if a que comes in UPSC like which of the following are decomposers ? will you mark scavengers too ? both are different as per sources outside NCERT
    same goes for geography , a statement is given in NCERT that salinity increases with depth , generally. but savinder singh says ” no fixed pattern ” in mid latitudes it is opposite of tropics and regional variations are also immense . will you mark this as right ?
    @insights or any one willing to help ?

  2. 34.Rainfall generally decreases as we move from equator to poles.- Agreed

    but in India itself in the western parts rainfall increases(koppen classification) unlike eastern. So here we need to emphasize generally before opting it correct?

    39.If the second statement would be-The roots absorb nutrients through osmosis. Is it correct? Or it should be diffusion?

    82.What do you understand by the term “Sea floor spreading”?
    A. Forward advancement of the ocean floor towards shorelines….What’s wrong in this?

      1. sir , the que is asking “what do you understand by sea floor spreading” not where does it occur. sea floor spreading is a process which harry hess identified by combining the two factors i.e generation at MOR and consumption at trenches which are shorelines. so sea floor spreading is forward advancement of ocean floor towards shore where the oceanic basaltic plates get consumed !!!! shouldn’t it be right ?

      2. Statement isn’t saying SFS accurring at shorelines but only advancement and yes if SFS occurs at mid oceanic ridges which is true then isn’t it obvious that the ocean floor forward towards shorelines(which is also the reason for subduction)?

      3. 82) Don`t you think SFS is cause and forward advancement of oceanfloor towards shorelines is its effect?

      4. I know it’s late but question 23 of test 6 about mangroves- Coral reefs don’t grow in silty waters and mangroves do, so how are they going to provide defense when they don’t grow in areas of mangroves. I am not sure if the region in gujarat coincides with coral and mangroves, if it is so my query is solved 🙂

      1. Thank you sir. Also, since so many questions in the mains came from Secure 2015, I am going to take Secure 2016 very seriously.

      2. sir my test-6 screen is showing -“questions are loading for past 15 minutes” but test is not coming. Shall I refresh the page or what? pls help

        1. Please try clearing the cache, cookies or change the browser. It was work. 🙂

  3. According to Q.94 , one cannot acquire Ebola during the tattooing process but as per WHO, Ebola may spread through surfaces and materials contaminated with bodily fluids of affected person. Please tell me what am i missing here.

      1. It because not every body fluid exchange is harmful. For e.g. Sharing food doesn’t cause AIDS even though it may involve some form of saliva exchange.

    1. It because not every body fluid exchange is harmful. For e.g. Sharing food doesn’t cause AIDS even though it involves some form of saliva exchange.

      1. But I couldn’t find any source which says Ebola cannot spread through tattooing.. in fact most site says there is such possibility.. Can u please provide us with such source which clears the doubt.Thank u

        1. Ebola spreads easily when compared to other two diseases. So, tattooing can easily spread the virus. The answer should have been A instead of C

  4. can anybody please let me know how to study sociology class 11 as per test 7.

    i am finding it difficult to grasp the topics.. any help will be appreciated .. thanks

    1. For Prelims, you should only pick up the key words key facts.

      For Mains, you should only focus on broad topics and those blue boxes.

      1. Sir I couldn’t find anything useful in Sociology from prelims perspective. Please help.
        @disqus_uqEmtDSccB:disqus bro how do manage to cover those chapters? I read the 1st half chapters than after getting nothing much just gave a look to all 5 🙁

        1. It is not necessarily that whatever insights has given u must be studied
          U can ignore. …after some evaluation
          It my personal view. ..which I follow

        2. hello I4anI,
          just as insights said take a chapter, refocus your mind, cover the basic definitions and facts as per prelims plus those blue boxes which will be helpful in mains to quote in paper 1 sociology part etc.
          one cant ignore these subjects seeing the uncertainity of the exam.
          so start afresh make a timeline, i find only the first chapter little confusing rest i went down with the flow..

  5. I am not clear with the role of coriolis force in Equatorial Counter current(Q.97). can anyone explain it please.

      1. The counter currents lie to a bit North and South of the equator.

        Also, in the Indian Ocean, their circulation is affected by the impact of the reversing Asian monsoon winds. Hence, the importance of coriolis force.

      2. @uda@disqus_xWlObb4b3X:disqus and @sne@disqus_JBs5WmzQxi:disqus are you guys convinced with the explanation ?

      3. corriois force Cf = v sin(theta)
        v= velocity of winds
        theta = angle of latitude
        At equator theta = 0, so cf = 0

    1. The counter currents lie to a bit North and South of the equator.

      Also, in the Indian Ocean, their circulation is affected by the impact of the reversing Asian monsoon winds. Hence the importance of coriolis force.

      1. sir ,i beg to differ with your explanation. coriollis force is not like a switch which trigger up just above equator, if that was the case why tropical cyclones are not found in a belt of 0-5/8 N/S , it is because the coriollis is weak!!!! and if coriollis act on this current why it doesn’t show deflection to right and left in summers and winters ?
        secondly the asian monsoons reversal is not only because of coriollis but involves other factors such as findlator jet in africa and ITCZ shifting to tibetian plateau. if only coriollis was the reason then all continents in that region would have experienced monsoons !!!!
        moreover countercurrents are subsurface currents which flows in between the two equatorial currents, so how can coriollis contribute ? pls corrrect me if i am wrong ?
        if this is true than coriollis would also affect tropical cyclones just above equator and equatorial currents too ?

        1. I agree with your argument regarding no effect of coriolis force on counter equatorial currents.
          But the point you mentioned that counter equatorial current is subsurfacial current is partially true as counter equatorial current flows on the surface as well as below the surface from west to east.

      2. @Insights Prelims Test Series: Please explain !! This does not clarify much.

        I just read something about the Asian monsoonal winds playing some role in Counter-Equatorial Currents. But, it is disputed, especially when monsoon is seasonal and restricted to a small area.

    2. are you convinced with the explanation given by insights? if you get it then pls clear my confusion!!!!!

  6. @inINSIGHTS

    this year after prelims in many questions many students debated about answers which are ambiguous , so can any one of you help me in this . i mean what we should mark , what is given in NCERT or what is correct . this dilemma is mainly in science and geography .and they are increasingly asking such ambigous questions .
    for eg : in NCERT in decomposers they even used scavengers eg. so if a que comes in UPSC like which of the following are decomposers ? will you mark scavengers too ? both are different as per sources outside NCERT
    same goes for geography , a statement is given in NCERT that salinity increases with depth , generally. but savinder singh says ” no fixed pattern ” in mid latitudes it is opposite of tropics and regional variations are also immense . will you mark this as right ?
    @insights or any one willing to help ?

    1. We can only hope that UPSC will stop giving such questions. When in doubt, stick to NCERT unless it is totally absurd to.

      Decomposers and scavengers are different. So, no.

      NCERT also mentions that salinity has no fixed pattern in every case. But, it generally increases with depth.

  7. In Q.18 How Coriolis force affect formation of meanders?
    It would be very minor

    In Q.90 how does “Terrestrial planets being near to the sun
    faced more intense solar winds” is the reason of losing their gases. Solar wind
    can only replace them in periodic basis but cannot wash them out permanently at
    least in the opposite side of the planet. The reasons behind the escape of air
    are the gravitational force and root mean square velocity of air particle.

    1. q18 it is written in ncert so take it from granted…
      quoting from a technical paper to substantiate…
      “……Rather than rivers flowing directly as they would be in a nonrevolving system, the flow tends to the right in north of the equator and to the left in south of it. In the nineteenth century, naturalist Karl Ernst von Baer observed that the rivers in the northern hemisphere do most of their erosion on the side to the right of the direction of flow; and on the left in the southern hemisphere.
      The reason is attributed to the Coriolis effect. Albert Einstein (1926) simply observed that as the stream flow curves on the earth surface, the Coriolis effect induces rotational motion to the flow. The flow moves helicoidally downstream, as if a corkscrew moves. Einstein’s discussion on the cause of meander was rather casual, but characteristically insightful, as his attribution of secondary currents to the Coriolis force might have been among the earliest……..”

    2. 90. The planets revolve around the Sun, which makes it possible to possess gases on all sides. It is a cosmic scale phenomenon which has been mentioned very clearly in the NCERT books. One can’t speculate what would have happened. We must ultimately rely on scientific research.

  8. Q. 40 . Which of the following forces affect Ocean currents ?

    As per the justification, Underwater Earthquakes also affect Ocean currents like Tsunami.

    But I am not clear on this point because Tsunami is a Wave, it is not a current, so I doubt underwater earthquakes affect the Ocean Current which is a continuous, directed movement of seawater. Please clarify.

    And once again I request you (like I have been doing since Test 3) to kindly provide the “corrections” of the answers if any.

    Thank you

      1. An ocean current is regular Movement of water either on the surface on in the depth of ocean. Any event that can change the patterns of water circulation significantly will affect ocean currents. Localised waves do not affect Ocean currents, but something as massive as Tsunami will change the pattern of water flow, density patterns of ocean water, salinity etc. and thus the ocean currents.

        1. I think its too late but still…
          Tsunami is a wave, that means it doesnt involve movement of water, it only transfers energy.. in open ocean, tsunami wave is not even a meter high.. so i think, no variation in circulation or density will occur in open oceans.. Tsunami displaces water only in coastal areas where depth is too low..

        2. question 88: about evidence of expansion of universe. UPSC says supernova explosion do not give information about the universe expansion. contradictory to your answer. please clarify

          1. We cannot comment on why UPSC believes Supernova explosions can’t be the answer. But, many sources clearly indicate that one of the first evidences for the accelerating expansion of the Universe comes from Supernova observations.

    1. Tsunami is a wave and not current , you are right , in currents particles move forward but not in wave. as far as affect of underwater EQ is concerned , the ripples generated by it , for eg in tsunami , the particles move at their position and wave acquire ht. as it approach the shore and so it can affect the current (like breaking the flow or atleast can change the direction) ,which are near the coast only.

    2. An ocean current is regular Movement of water either on the surface on in the depth of ocean. Any event that can change the patterns of water circulation significantly will affect ocean currents. Localised waves do not affect Ocean currents, but something as massive as Tsunami will change the pattern of water flow, density patterns of ocean water, salinity etc and thus the ocean currents.

      1. But i think that effect is temporary and it does not alter the very nature and direction of current…. Does that effect last long or is momentary ???

      2. Modification of Ocean currents is also due to the permanent features such as coastline,mid oceanic ridges.
        According to your idea,there are innumerous underwater earthquakes happening which would be affecting the water movement in some degree even if least, can that be called modifications in ocean currents?
        If this is true I fear ocean currents will change daily, which goes against the definition of ocean currents.

        1. A possibility and an actual occurrence are two different things. For e.g. the statement, “An earthquake can cause severe damage to life and property” is not incorrect even though there are innumerable earthquakes which hare hardly noticeable. An earthquake of sufficient magnitude will cause damage.

          The same is true for underwater earthquakes. A large quake will change the pattern of ocean currents temporarily.

          When objective papers are set for such examinations, examiners often use these keywords like ‘may’, ‘can’ to check whether the student is able to link the numerous possibilities around a concept.

          If you do not use ‘possibilites’, even the option “Salinity variations in water” will be wrong, as ocean salinity will vary with evaporation on a daily basis (not noticeably however), and if this is the case, then ocean currents would be modified everyday.

          Whenever you see the keywords, ‘can’, ‘may’, ‘only’ etc, pay special attention to them in picking up the right option. Thank you.

          1. Yes that is definite that words such as ‘can’,’may’ etc must be looked into.
            But in this question there was no such word ‘can’!!!!

          2. hi insights..just a query…u have asked us to study previous year csp papers..but ppl say none of them get repeated… sine this is my first attempt, i’m facing shortage of time..so i naturally prefer investing time on stuffs which will have good returns (in terms of questions in exam)..should i really go through those previous year papers of csp? will it hav decent return on investment (of time)?? pls reply.

              1. hi insights! ‘Pinus tree can metabolise excess nitrogen oxide in atmosphere’, (qn 45, test6) does it mean pinus tree can absorb excess nitrogen oxide in atmosphere?

          3. Hi @insightsprelimstestseries:disqus

            the question says: “which of the following forces influence ocean currents?”

            there is no use of word “may”, “can” etc.. that may signify us to think on temporary possibilities as well. Please suggest.

      3. Also with regards to q 41,In the zone of mixing of cold and warm currents,there is the occurrence of dense fog which hampers the reach of sunlight on the surface.
        Your explanation says Planktons need sunlight for there growth, so accordingly there growth would have been hindered in mixing zones.
        As far as I know Planktons need shadowy condition along with other condition such as nutrients for growth which then attract zooplanktons and swarms of fishes.So it becomes fishing belt.
        And how mixing zone bring nutrient rich deep water on the surface.For example grand bank is the meeting point of cold labrador current which is mainly due to ice melt and gulf stream which is a warm current.

          1. I had the same doubt.

            Read the link given by you completely. It says that nutrient is needed by plaktons which is universally accepted fact but it does not establish the fact that how the intermixing of water is providing the nutrients.

            Even refered to NCERT page 124 as given in the solutions but it says that it helps “replenish the oxygen” again no relation to nutrients.

            Please clarify from some credible source.

            Thanks

            1. FAO is a highly credible source. The absence of explanation in other sources does not mean that the concept does not exist. 🙂 NCERT does not explain inter-mixing of waters fully.

              Inter-mixing of water is the single most crucial process for nutrient cycling and phytoplankton growth. Please stick the explanation and answers provided. Thank you.

  9. Insights Prelims Test Series Q 91.. Ebola spreads by body fluids.. So tatooing may lead to spread… Why is it excluded in the answer??

    1. It because not every body fluid exchange is harmful. For e.g. Sharing food doesn’t cause AIDS even though it involve some form of saliva exchange.

      1. Both aids and Ebola can spread by tatooing.. Isn’t it? It is possible to get if the same syringe / needle is used for tattooing.. Ebola is a highly dangerous disease.. The health care people don’t even touch Ebola patients, so tattooing will lead to spread.. Sir, I am not convinced by the explanation.

  10. Sir how many student are appearing for test series ….so that we can estimate about our rank…….gabar is waiting for reply guru ji….

  11. one thing i have noticed since test 1…why the aspirant base for the test is getting downward slope with each test passes?

  12. Dear Insights,

    I have paid long back for insight test series. BUT STILL UNABLE TO GIVE THE TEST. Due to some reason i was not able to give test on time. But now when i tried giving the test, what happened is, whenever i click on Start test the page automatically bring me back to the TEST SCHEDULE PAGE. This way, i am not able to give my test. Whenever i again click on the test it shows ” Your test has been finished ” NOW HERE I HAVE NOT GIVEN ANY SINGLE TEST. But it shows this flag only. PLEASE CHECK YOUR RECORD and REPLY ME ASAP. So i can start giving test.

  13. Q. 48) DDT is organic persistent pollutant—>soil absorbed.
    so by this they may impair metabolic fuction of plants …so why C option is inncorect?

    1. If it did, it would not have been used as a crop pesticide. Every PoP has a different impact. It need not impair every form of organic life in the same way every toxin is not harmful to eBay living being.

  14. @insightsprelimstestseries:disqus-I know you have been busy and so unable to address our doubts. But don’t the accessibility is one reason for which Insights became famous.

    QUE 19 – in GC Leong page 40 and 41 and also in savinder singh page 218 , it is given that ” youth ful stage is characterised by deep , narrow valley as their is no lateral erosion , whereas in mature stage due to lateral corrasion the valley widens ” . i know NCERT mentions what you have given in explanations but what is the right answer ?
    going by davisian theory and GC leong , why the best answer shouldn’t be D !!!!

    1. V-shaped valleys form in mountains or other highland areas where streams are in their beginning or youthful stage. Here they are flowing rapidly down steep slopes. Moreover, high sediment load can also be found in lower reaches of the river, where V-shaped valleys are unlikely to be found. So, the most appropriate answer would be option (a). 🙂

      1. that is what i am saying the valleys in youthful stage are NARROW and DEEP and not shallow !!!! shallow is a feature of mature stage when valley widening also takes place 🙂 🙂

        1. What you have assumed is that river Valleys pre-exist and with time they are filled with sediment. No.

          Valleys are formed due to the bed erosion by fast flowing rivers. They don’t pre-exist as narrow and deep Valleys. So, when the Valley is formed in river’s youthful stage the dug out is still shallow. It gets deeper as the erosion continues in the maturity cycle of the river.

          1. just last time and i will not ask again 🙂 , these are two images from http://www.sswm.info/sites/default/files/reference_attachments/IMMOR%202006%20Classification%20Rivers.pdf and geography made simple.
            u are correct that initially river starts eroding then valleys are small , but considering the life span the youthful stage is characterized by deep , narrow valleys and once the eroding power wanes lateral starts .
            the confusion is about SHALLOW and WIDE valleys!!!! wide is definitily a post youth feature , but m not sure about shallow in youth , can we definitely mark it ? relying on you now completely :))

  18. @Insights Prelims Test Series

    QUE 36 about magnetic activity and sun spots, they do effect magnetic activity , not its intensity that the earth generates from its core but the magnetosphere as a whole , i am posting a link form dicovery::

    http://news.discovery.com/space/powerful-solar-storm-rips-into-earths-magnetic-field-150317.htm

    “Our planet has a global magnetic field called the magnetosphere, so should a CME hit the magnetosphere at just the right alignment, the CME’s magnetic field can reconnect, causing intense magnetic disruption, injecting the magnetosphere with huge quantities of plasma from the sun. In this situation, the CME is said to be “geoeffective” and the resulting geomagnetic storm can be extreme”

    1. When solving science based questions, you should be very careful. One, UPSC Prelims is not a recruitment exam for Indian research scholars, and two, you should strictly go by the option given in the question, and not try to interpret too much into it.

      The distortion of magnetic field occurs at very large distance from earth, at round 60-70,000 Km. You can practically consider it to be outside of earth’s magnetic activity, even though it exists there. In a sense, even the revolution of earth around the Sun will affect its magnetic field as it comes closer or goes away from the Sun and face greater or smaller plasma discharge. If we consider all this, will we be able to mark right answers in any such questions on earth’s magnetism in UPSC?

      Perhaps everything that happens in the Universe affects the earth. We need not consider each and everything and answer like generalist administrators. This exam tests very basic science skills upto 12th Std. This should always be kept in mind. 🙂

    1. Home charges include not just the expenses of the Secretary of State office in London, but also the charges for maintaining civil administration, army, stores, guaranteed railways etc.

                1. The non-legumes used as green manuring crops provide only organic matter to the soil (after decaying). The legumes used as green manuring crops provide nitrogen (during decay) as well as organic matter to the soils (after decay). Thank you.

    Q71)Asteroids collided on earth MILLIONS of yrs ago. So they should be the basic source of minerals?

    1. Hey Disco Dancer, I think all your questions can be answered if you read the NCERTs in greater detail, repeatedly.

    2. We suggest you to carefully read NCERTs and then attempt tests to score higher. For Q34, 36 please refer the explanations.

      12. It is also called Indian plate.

      40. Earthquakes affect the movement of ocean water temporarily causing changes in density and flow patterns. The question mentions about a possibility, see the keyword ‘can’.

      41. Suitable temperature is not the only necessary condition for growth of phytoplankton. Such ideal temperatures can be found at many ocean regions which are not rich in phytoplankton growth.

      71. No. Asteroids are insignificant when compared to magma. It is like comparing the light of a bulb with that of the Sun. 🙂

  21. Hey guys I have missed 3 tests due unforeseen circumstances… It will be a big help of anyone can give me an overview of how they were .. Were they too difficult .. Should I study for them first and give them.. Or should I give the subsequent tests and concentrate on the missed ones later … Please any suggestion is more than welcome 🙂

    1. The first three tests will build your foundations from basic books (6-8th) which is very important. UPSC focuses a lot on these books. This year, so many questions from the first three tests were directly or indirectly asked in Prelims 2015.

      1. I missed 4th 5th and 6th … I gave the first three .. Should I prepare for 8th and do those later or should I do those first ?

        1. 4th and 5th are totally general science oriented tests…i would suggest prepare for 8th and 4th simultaneously. …like morning time for test 8 and evening for test 4 …morning for test 9 and evening for test 5 and so on…u can cover the backlog. …or anyother way u like to….its not like if u don’t study for the previous tests u wont be understanding the next ones…so its upto you. ..

            1. That is not really a problem ma’am. Lemme tell you that. I did my GS classes alone last year in Chennai and planned to do my optional Socio this year so that I get everything right for my attempt in 2016. And i wrote all tests last year as well since they are a part of my GS classes. I didn’t study the NCERTs suggested here but I did the tests well. And I don’t have a problem understanding the concepts either. I did world history NCERTs, History ones and geography. The rest are useful but the take off from them is very minimal. Including science. For which I feel the Unacademy s&T are doing justice. So don’t worry about the basic NCERTs. Just read through them like a story book and write the tests when you’re not in your 100%.

  22. @INSIGHTS-WHAT TO READ IN 11TH CLASS NCERT-‘UNDERSTANDING SOCIETY’?WHICH CHAPTERS?PLZ REPLY SOON….

    1. You should read it from Mains point of view. Questions for Prelims will be automatically covered.

  23. Q.34.As per explanation,Poles receive lesser solar insolation, have lesser evaporation and rainfall. Reverse is

    true for equator and question asks rainfall generally increases as we proceed from poles to equator but what about sub tropical region where rainfall is lesser than sub polar region due to subsidizing air mass.It implies rainfall doesnot increases only,it decreases also i.e. at sub-tropical region.please clarify..

    1. For sub-tropics it depends on the location and season. For e.g. on the poleward sides of the eastern coasts precipitation may increase. But, this behaviour cannot be generalized. The relationship that generally precipitation decreases from equator to polewards is a standard result, and has also been asked verbatim in UPSC Prelims.

  24. Hello guys n sir , my score in ecology part is very poor in all six tests …..can anybody give suggestions how to improve that particular area

    1. NCERTs do not explain in detail several keywords/concepts/terminologies that they contain. You should do some research from internet and try to understand them better. As most questions will be concept based, you will then be able to handle them.
