Solution of the UPSC Civil Services (Preliminary) Examination 2012 – GS Paper 1

11. The increasing amount of carbon dioxide in the air is slowly raising the temperature of the atmosphere, because it absorbs
[A]the water vapour of the air and retains its heat
[B] the ultraviolet part of the solar radiation
[C]all the solar radiations
[D]Infrared part of solar radiation

Infrared part of solar radiation
D is the correct answer. You may read more about it here


12. Which one of the following sets of elements was primarily responsible for the origin of life on the Earth?
[A]Hydrogen, Oxygen, Sodium
[B]Carbon, Hydrogen, Nitrogen
[C]Oxygen, Calcium, Phosphorus
[D]Carbon, Hydrogen, Potassium

Carbon, Hydrogen, Nitrogen
The correct answer of this question, as most of you know, is Carbon, Hydrogen and Nitrogen. In fact, the early biochemistry was not simply the reactions of Carbon, Hydrogen, Nitrogen and Oxygen was bit far from it, was CO2, N and water resulting in the organic acids such as oxalic acid.


13. What are the reasons for the people’s resistance to the introduction of Bt brinjal in India?
1. Bt brinjal has been created by inserting a gene from a soil fungus into its genome.
2. The seeds of Bt brinjal are terminator seeds and therefore, the farmers have to buy the seeds before every season from the seed companies.
3. There is an apprehension that the consumption of Bt brinjal may have adverse impact on health.
4. There is some concern that the introduction of Bt brinjal may have adverse effect on the biodiversity.
Select the correct answer using the codes given below :
[A]1, 2 & 3 Only
[B]2 & 3 only
[C]3 & 4 only
[D]1,2,3 & 4

3 & 4 Only
The first statement is incorrect. The second statement is also NOT correct. Bt Brinjal is NOT a terminator seed, as of now. link The third statement is obviously correct. The 4th statement is dubious but is a correct statement as it says –some concern that–


14. Other than resistance to pests, what are the prospects for which genetically engineered plants have been created?
1. To enable them to withstand drought
2. To increase the nutritive value of the produce
3. To enable them to grow and do photosynthesis in spaceships and space stations
4. To increase their shelf life
Select the correct answer using the codes given below:
[A]1 & 2 Only
[B]3 & 4 Only
[C]1, 2 & 4 Only
[D]1, 2, 3 & 4

1, 2 & 4 Only


15. Consider the following statements:
The most effective contribution made by Dadabhai Naoroji to the cause of Indian National Movement was that he
1. Exposed the economic exploitation of India by the British
2. Interpreted the ancient Indian texts and restored the self-confidence of Indians
3. Stressed the need for eradication of all the social evils before anything else
Which among the above statements is/ are correct?
[A]1 Only
[B]2 & 3 Only
[C]1 & 3 Only
[D]1, 2 & 3

1 Only
The second statement is incorrect. Regarding third statement, we should note that Dadabhai Naoroji was a great social reformer of Bombay, who founded the Parsi Law Association. But when we say he stressed the eradication of “all the social evils before anything else” we are not justifying the role of Dadabhai naoroji. This is an incorrect statement. Correct answer of this question is Only 1


16. With reference to Dhrupad, one of the major traditions of India that has been kept alive for centuries, which of the following statements are correct?
1. Dhrupad originated and developed in the Rajput Kingdom period.
2. Dhrupad is primarily a devotional and spiritual music.
3. Dhrupad Alap uses Sanskrit syllables from Mantras
Select the correct answer using the codes below:
[A]1 & 2 Only
[B]2 & 3 Only
[C]1,2 & 3 Only
[D]None of the above is correct

2 & 3 Only
The first statement is incorrect. We are told that Dhrupad has its origin in back to Vedas period. The modern dhrupad probably descends from a form (dhurva) mentioned in the Na¯tyasha¯stra that developed in the Gwalior region (central Indo-Gangetic Plain) and probably reached a peak of popularity in the sixteenth century. Most dhrupads are religious in nature, praising Hindu gods (particularly Krishna) although some texts praise kings. The performance of dhrupad almost always begins with an introductory, free-time a¯la¯p, which can range from a brief affirmation of the melodic underpinnings of the performance (in religious contexts) to elaborate noteby- note explorations of the possibilities inherent in the underlying pitch resources of ra¯ga (melody). The concert dhrupad a¯la¯p generally has two sections: the first (the a¯la¯p of the a¯la¯p) has the usual pattern of a growing pitch ambitus in free tempo, and the second (the nomtom or jor), an unmeasured, but pulsed, presentation of the ra¯ga.


17. How do you distinguish between Kuchipudi and Bharatanatyam dances?
1. Dancers occasionally speaking dialogues is found in Kuchipudi dance but not in Bharatanatyam.
2. Dancing on the brass plate by keeping the feet on its edges is a feature of Bharatanatyam but Kuchipudi dance does not have such a form of movements.
Which of the statements given above is/are Correct?
[A]Only 1
[B]Only 2
[C]Both 1 & 2
[D]Neither 1 nor 2

Only 1
The first statement is correct as Kuchipudi presents more realistic acting occasionally including dialogue spoken by the dancers. Another unique feature of Kuchipudi is the Tarangam, in which the performer dances on the edges of a brass plate, executing complicated rhythmic patterns with dexterity, while sometimes also balancing a pot of water on the head. So, second statement is incorrect. Correct answer is Only 1


18. With reference to the religious history of medieval India, the Sufi mystics were known to pursue which of the following practices?
1. Meditation and control of breath
2. Severe ascetic exercises in a lonely place
3. Recitation of holy songs to arouse a state of ecstasy in their audience
Select the correct answer using the codes given below:
[A]1 & 2 Only
[B]2 & 3 Only
[C]3 Only
[D]1,2 & 3

3 Only
As far as meditation is concerned, Sufi practice Muraqaba which is a form of meditation only. This is not related to medieval history of India. First statement is incorrect. Second statement is also incorrect. Third is correct. Correct Answer Only 3.
The question would invite a lot of research though. My answer has raised some counter questions also but we maintain our answer as correct. A few snippets / sources would suffice the reason, one of them is as follows:

source of above snippet is page This Book, Page 232


19. The Rowlatt Act aimed at
[A]compulsory economic support to war efforts
[B]imprisonment without trial and summary procedures for trial
[C]suppression of the Khilafat Movement
[D]imposition of restrictions on freedom of the press

imprisonment without trial and summary procedures for trial


20. The Lahore Session of the Indian National Congress (1929) is very important in history, because:
1. The Congress passed a resolution demanding complete independence
2. The rift between the extremists and moderates was resolved in that Session
3. A resolution was passed rejecting the two-nation theory in that Session
Which of the statements given above is/are correct?
[A]1 Only
[B]2 & 3
[C]1 & 3
[D]None of the above

1 Only
Jinnah’s Two Nations Theory came up in March 1940, so how could they reject in 1929. Statement 2 is also incorrect. The correct answer of this question
is Only 1 .

    For Q13 – BT Brinjal one ..statement 1 is incorrect as the gene used is not that of soil fungus but of soil bacteria :) ….as there is no option containing 2 3 4 ….so ans has to be 3 and 4 only.

    For Q71 – Seabuckthorn — its also used as biodiesel..though its use as of now is limited, but then it has great potential. Searching in google for Seabuckthorn as biodiesel……reveals many websites that says about it …so correct option should be D – all 1,2,3,4 . Seabuckthorn timber also has great value .

    Hi Sir,

    Thanks for your excellent support to the aspirants.

    One favor I would like to ask. In the view of this year’s pattern of GS Paper-I, It needs a very good understanding of the topics for the best guess. If you could provide section-wise quiz like dividing Modern History in periods, or dividing Geography of India in Physical Geo, Human Geo, Climatology & atmospheric variations etc., it will help us in concentrating on the very topic and a better assessment of the preparation.

    Regards,
    Jitendra
