CSAT 2013 Official Answerkey Released

  • After almost one year wait, UPSC has uploaded the answer key of the civil service and forest service prelim exam CSAT-2013 exam. Click ME
  • But we need original question paper to “find” the ‘question number’. here are the links
MS-Word FormatPDF Format
  1. General Studies Paper
  2. Aptitude Paper
  1. General studies paper
  2. Aptitude
  • Not every question  converted properly from PDF to word,
  • but “Find” option works reasonably good, just type a few key phrases.
text unsearchable, and PDF too big in size.

After prelim-2013 I had published answer keys myself, but was unable to locate exact reference to some of the MCQs. So, let’s check what UPSC answer key has to say..

Decision making

CSAT Paper II (2013) Decision Making Question No. 75 to 80
Question number (Booklet A)UPSC official answerkey
75. House-allotment to personal Secretary
  • A-explain him why allotment can’t be done.
  • C-Agree with office note to show unbiasedness.
76. Delhi taxi driver paying bribe to transport office. Should you turn blind eye?
  • A-ask clerk to give back money
  • C-take note of incident, later complaint
77. poor man came to complain collector, but collector busy
  • C-call senior subordinate, ask him to solve.
  • D-take complaint yourself and ask a few relevant questions
78. sugar quota order vs friend’s wedding
  • B-refuse to give extra sugar
  • C-show him copy
79. How to communicate to junta to adopt family planning?

  • C-incentives for adopting a family planning devices.
80. collegue asking you to leak university paper for his ‘last attempt’ son.
  • B-refuse
  • C-explain violation of trust.

My own answerkey (under CSAT strategy article)  matches with UPSC’s. Just slight difference in just one single question: family planning communication:

  • UPSC says A or C
  • I had taken A or D

In short, by and large, Mrunal’s EBDTM (eliminate bad decision) technique works. Click to learn the technique on how to eliminate wrong decision.
Anyways, let’s move on, some GS MCQs that had debatable answers due to lack of clear cut reference. In all of the following questions, I’m using Question booklet A.

Swamp deer

Q87. Consider the following fauna of India:

  1. Gharial
  2. Leatherback turtle
  3. Swamp deer

Which of the above is/are endangered?

  1. 1 and 2 only
  2. 3 only
  3. 1, 2 and 3
  4. None
Why was it debatable?UPSC’s official answer
India government websites click-me say Swamp deer endangered, while IUCN says it is only vulnerable. Hence debate between option A and C.
  • C: 1, 2 and 3
  • Meaning if sarkari sites say Swamp deer endangered then its endangered. The Examiner doesn’t refer to IUCN redlist.
  • I was taking IUCN as reference hence got wrong here.

Balance of Payment

41. The balance of payments of a country is a systematic record of

  1. all import and export transactions of a country during a given period of time, normally a year
  2. goods exported from a country during a year
  3. economic transaction between the government of one country to another
  4. capital movements from one country to another
Why was it debatable?UPSC’s official answer
None of the given options fully described all components of Balance of Payment. (observe chart below)
  • A
  • As such my answerkey also picked A, due to the mess. But my Personal opinion – that all options are wrongly framed.
  • Import export is just Balance of Trade.
  • While Balance of payment is a bigger thing that includes investment, remittance etc. observe the following chart. So from there, none of the options are correct.
UPSC official answerkey doesn't agree with this BoP classification

Balance of Payment (Click to Enlarge)


Q99. The national income of a country for a given period is equal to the

  1. total value of goods and services produced by the nationals
  2. sum of total consumption and investment expenditure
  3. sum of personal income of all individuals
  4. money value of final goods and services produced
Why was it debatable?UPSC’s official answer
Different books gave different formulas and people interpreted it in multiple ways.
  • D. money value of final goods and services produced.
  • My answerkey had “A”- so I was wrong in the interpretation here.

Ecosystem productivity

23. Which one of the following is the correct sequence of ecosystems in the order of decreasing productivity?

  1. Oceans, lakes, grasslands, mangroves
  2. Mangroves, oceans, grasslands, lakes
  3. Mangroves, grasslands, lakes, oceans
  4. Oceans, mangroves, lakes, grasslands
why debatableUPSC’s official answer
  • Different sources gave different interpretation based on how you look at “productivity” i.e. rate wise or in absolute quantity?
  • Hence both C and D seemed correct. (I wasn’t able to decide myself)
C. meaning they were asking in context of “rate” of biomass production.

Temperature coastal vs interior

60. The annual range of temperature in the interior of the continents is high as compared to coastal areas. What is / are the reason / reasons?

  1. Thermal difference between land and water.

  4. Heavy rains in the interior as compared to coasts.

  2. in Q no. 41
    choice C seems to be correct

  3. 37. Which one of the following describes best the concept of Nirvana in Buddhism?
    answer A is correct as per ncert 6th class social studies…. our past….chapter 6 or 7th….buddha says ……give up your desires you will get mukti…..desire is curse of all things…

  4. friction depends on area of contact

  5. Sir, UPSC considers “Critically Endangered” as “Endangered” ? Since Turtle and Gharial are “Critically Endangered” but answer key shows 1,2,3 are correct.

  6. total value of goods n services is gdp….national income=GDP -NET INDIRECT TAXES(INDIRECT TAXES – GDP)….I GUESS this has been called final money value of goods n services…..jus read ds in ncert….thot might help :)

    1. HIII neha can i get ur no plzz i want some advice from u….if yes then call me +918000130011

  7. oh sorry…..nat income = gdp – net indirect taxes
    =gdp- (indirect taxes -subsidy*)
    by mistake wrote gdp

  8. For question no.41 UPSC answer(A) is correct. BOP in accounting and broader sense refers to export and import of ALL transaction.(including goods,service,capital all remittance and receipt )
    Balance of Trade is the export and import of GOODS ONLY…

  9. not able to dwnlod ncert history.what to do now!!!!!

  10. Regarding Q23. Productivity is never absolute, nor cumulative. Productivity is always a rate. Please correct that. :)

    Regarding Q 99. It can never be A. Its not the total value, we have to minus the subsidy etc! so, D is right! It is the ‘money’ value of goods and services! the word ‘final’ makes all difference!! because, we need to minus the intermediaries from the ‘total’!! :)

    please do note them! Thank you. :)
