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

May 21, 2012 June 20, 2019

41. With reference to the guilds (Shreni) of ancient India that played a very important role in the country’s economy, which of the following statements is/are correct?
1. Every guild was registered with the central authority of the State and the king was the chief administrative authority on them.
2. The wages, rules of work, standards and prices were fixed by the guild.
3. The guild had judicial powers over its own members.
Choose the correct option:
[A]1 & 2 Only
[B]3 Only
[C]2 & 3 Only
[D]1,2, & 3

1,2, & 3
This question is based upon a very special reference made by Kautilya in Arthashstra about the registration of Guilds. He had devises the method of regulation of guilds by:
1. Registration of the Guilds
2. Laying down the checks and balances on the activities of the artisans and forming the penal laws to prevent their transgression
3. Appointment of special tribunals to administer the laws.
All statements in this question are correct.


42. The distribution of powers between the Centre and the States in the Indian Constitution is based on the scheme provided in the:
[A]Morley-Minto Reforms, 1909
[B]Montagu-Chelmsford Act, 1919
[C]Government of India Act, 1935
[D]Indian Independence Act, 1947

Government of India Act, 1935
As far as legislative powers are concerned, the constitution of India follows a system that is similar to the Canadian Constitution, but Indian Constitution has a more elaborate Concurrent List which was a result of following the Australian Constitution. The scheme of division of legislative powers is almost same as in the Government of India Act 1935. Then, if we talk about the distribution of the taxing power and revenues under the Indian Constitution, we find that it follows the scheme of 1935 act, which was actually based upon the experiences of 65 years since the times of Lord Mayo. Correct answer is C.


43. Despite having large reserves of coal, why does India import millions of tonnes of coal?
1. It is the policy of India to save its own coal reserves for future, and import it from other countries for the present use.
2. Most of the power plants in India are coal-based and they are not able to get sufficient supplies of coal from within the country.
3. Steel companies need large quantity of coking coal which has to be imported.
Which of the statements given above is/are correct?
[A]1 Only
[B]2 & 3 Only
[C]1 & 3 Only
[D]1,2, & 3

2 & 3 Only
This question does not need an explanation.


44. A person stood alone in a desert on a dark night and wanted to reach his village which was situated 5 km east of the point where he was standing. He had no instruments to find the direction but he located the polestar. The most convenient way now to reach his village is to walk in the:
[A]direction facing the polestar
[B]direction opposite to the polestar
[C]direction keeping the polestar to his left
[D]direction keeping the polestar to his right

direction keeping the polestar to his left
UPSC has lifted this beautiful question from UPSC Prelims paper 1992. Its easy, the person would walk in the direction, keeping the polestar to his
left.


45. Recently, there has been a concern over the short supply of a group of elements called ‘rare earth metals’. Why?
1. China, which is the largest producer of these elements, has imposed some restrictions on their export.
2. Other than China, Australia, Canada and Chile, these elements are not found in any country.
3. Rare earth metals are essential for the manufacture of various kinds of electronic items and there is a growing demand for these elements.
Which of the statements given above is/are correct?
[A]1 Only
[B]2 & 3 Only
[C]1 & 3 Only
[D]1,2 & 3

1 & 3 Only
The second statement is not correct. Also note that China has now (day before yesterday) lifted the restrictions :)


46. Biomass gasification is considered to be one of the sustainable solutions to the power crisis in India. In this context, which of the following statements is/are correct?
1. Coconut shells, groundnut shells and rice husk can be used in biomass gasification.
2. The combustible gases generated from biomass gasification consist of hydrogen and carbon dioxide only.
3. The combustible gases generated from biomass gasification can be used for direct heat generation but not in internal combustion engines.
Select the correct answer using the codes given below:
[A]1 Only
[B]2 & 3 Only
[C]1 & 3 Only
[D]1,2 & 3

1 Only
The second statement you needed to eliminate because CO is a major concern. Then, third statement is also incorrect.


47. What is the role of ultraviolet (UV) radiation in the water purification systems?
1. It inactivates/kills the harmful microorganisms in water.
2. It removes all the undesirable odours from the water.
3. It quickens the sedimentation of solid particles, removes turbidity and improves the clarity of water.
Which of the statements given above is/are correct?
[A]1 Only
[B]2 & 3 Only
[C]1 & 3 Only
[D]1,2 & 3

1 Only
UV does not change the taste, odor or color of the water.


48. Graphene is frequently in news recently. What is its importance?
1. It is a two-dimensional material and has good electrical conductivity.
2. It is one of the thinnest but strongest materials tested so far.
3. It is entirely made of silicon and has high optical transparency.
4. It can be used as ‘conducting electrodes’ required for touch screens, LeOs and organic LEOs.
Which of the statements given above are correct?
[A]1 and 2 only
[B]3 and 4 only
[C]1, 2 and 4 only
[D]1,2,3 & 4

1, 2 and 4 only
All of you must have eliminated the third statement.


49. Lead, ingested or inhaled, is a health hazard. After the addition of lead to petrol has been banned, what still are the sources of lead poisoning?
1. Smelting units
2. Pens and pencils
3. Paints
4. Hair oils and cosmetics
Select the correct answer using the codes given below:
[A]1,2 & 3 only
[B]1 and 3 only
[C]2 & 4 only
[D]1,2,3 & 4

1 and 3 only
Some people point that all options are correct, one of them citing example of cosmetics such as Sindoor. But Sindoor or Vermilion contains Mercury (HgS) not Lead. Then, UPSC does not expect you to be an expert in chemicals. They simply want to know whether you know that lead pencils are graphite pencils. Then, one reader says that in inks of some pens cause lead pollution. But do you think, it is really a health Hazard. Check applications of lead on wikipedia and you will find that you can not wipe-out lead from our life. In cosmetics, there have been some concerns about lead acetate in Lipstics in US. But in this question, UPSC intentionally does not give a choice to choose 1, 3 & 4. In our view, the correct answer is 1 and 3 only. You can read about the exposure routes here In Our view, the question could bring out more from the aspirants, if UPSC had put an option like Chinese toys,Hunting Bullets etc.


50. With reference to ‘stem cells’ frequently in the news, which of the following statements is / are correct?
1. Stem cells can be derived from mammals only.
2. Stem cells can be used for screening new drugs.
3. Stem cells can be used for medical therapies.
Select the correct answer using the codes given below:
[A]1 & 2 Only
[B]2 & 3 Only
[C]3 Only
[D]1,2 and 3

2 & 3 Only

    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.

  6. ravikvarma

    May 21, 2012 at 11:28 pm

    score ranging from 215 to 230…according to gktoday key..it is 217…is it in a comfortable margin?

    May 21, 2012 at 11:39 pm

    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 . Source : google :)

    Hi,
    Thanks a ton for the keys.!!

    The cutoff 168-170 you are expecting is the combined marks of paper 1 & 2 right?

  12. Tigin kalistus

    May 22, 2012 at 12:08 am

    Is the ‘cutoff marks’as predicted here is for ‘Paper-1’ or combined? I presume it is for combined but then cannot fathom out the criteria adopted in arriving at such a low cuttoff, if it is so.

    May 22, 2012 at 12:58 am

    the cutoff is for 1st paper only and for both paper combined.please clarify

  14. Gayathri

    May 22, 2012 at 1:20 am

    Sir,

    I would like to know if the cut off mentioned above(165-170) is the sum of both the papers. And also is there any separate cut off marks for each paper?

    Please do reply.
    Thanks.

    sirji this cut off is for GS1 and 2 combined right.. else im afraid only the paper setters and few others will make it..

  17. saurabh

    May 22, 2012 at 9:11 am

    In question 13, gene from soil bacterium Bacillus thuringiensis is used and not soil fungus. Option A seems to be incorrect.

  18. viswanadhas

    May 22, 2012 at 10:04 am

    In Q.57, NBFCs provide microfinance which promotes inclusive growth. Statement 1 seems to be correct too.

  22. saurabh

    May 22, 2012 at 11:54 am

    Q. 28, 1 & 3 both are correct. Since air is more dense close to the earh it can hold more heat than upper altitudes where air is thinner.

    May 22, 2012 at 12:44 pm

    There r many articles which have written about possible effects on biodiversity of Bt brinjal…and the langauge of statement 4 – there is SOME concern that bt brinjal MAY have adverse—– ….so statement 4 cannot be rules out . About the report of expert committee, yes they have said it, but there r numerous other reports, most recently buy greenpeace which says about adverse effects on biodiversity. Statement 2 ..about TERMINATOR SEEDS ..is not fully correct ..check this link please – http://www.thehindu.com/opinion/open-page/article317940.ece

    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

    May 30, 2012 at 10:01 am
