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

51. Consider the following statements:
Chlorofluorocarbons, known as ozone depleting substances, are used
1. in the production of plastic foams
2. in the production of tubeless tyres
3. in cleaning certain electronic components
4. as pressurizing agents in aerosol cans
Which of the statements given above is/are correct?
[A]1,2 and 3 only
[B]4 Only
[C]1,3 & 4 Only
[D]1,2,3 & 4

1, 3 & 4


52. A team of scientists at Brookhaven National Laboratory including those from India created the heaviest anti-matter (anti-helium nucleus).
What is/are the implication/ implications of the creation of anti-matter?
1. It will make mineral prospecting and oil exploration easier and cheaper.
2. It will help probe the possibility of the existence of stars and galaxies made of anti-matter.
3. It will help understand the evolution of the universe.
Select the correct answer using the codes given below :
[A]1 Only
[B]2 & 3 only
[C]3 Only
[D]1,2 & 3

2 & 3 only
You may read about it here


53. Which of the following is/are cited by the scientists as evidence/ evidences for the ‘continued expansion of universe?
1. Detection of microwaves in space
2. Observation of redshift phenomenon in space
3. Movement of asteroids in space
4. Occurrence of supernova explosions in space
Select the correct answer using the codes given below :
[A]1 and 2
[B]2 Only
[C]1,3 & 4
[D]None

1 and 2
The fourth statement seems correct but is not. The supernova explosions have helped astronomers determine both the distance of the galaxy and the redshift of the galaxy. The astronomers could then compare distance to expansion, and create a kind of ‘expansion history’ of the Universe. This showed that the expansion of universe was “increasing” means “the Universe’s expansion is accelerating”.


54. Electrically charged particles from space travelling at speeds of several hundred km/sec can severely harm living beings if they reach the surface of the Earth. What prevents them from reaching the surface of the Earth?
[A]The Earth’s magnetic field diverts them towards its poles
[B]Ozone layer around the Earth reflects them back to outer space
[C]Moisture in the upper layers of atmosphere prevents them from reaching the surface of the Earth
[D]None of the statements (a), (b) and (e) given above is correct

A is correct answer and is a reason of aurorae too.


55. With reference to the scientific progress of ancient India, which of the statements given below are correct?
1. Different kinds of specialized surgical instruments were in common use by 1st century AD.
2. Transplant of internal organs in the human body had begun by the beginning of 3rd century AD.
3. The concept of sine of an angle was known in 5th century AD.
4. The concept of cyclic quadrilaterals was known in 7th century AD.
Select the correct answer using the codes given below:
[A]1 and 2 Only
[B]3 and 4 Only
[C]1,3 & 4 Only
[D]1,2,3,4

1,3 & 4 Only
Lets analyze these statements:
1. Different kinds of specialized surgical instruments were in common use by 1st century AD.
This is an correct statement. We have been told that in ancient India, it was Sushrut who is known to be the first surgeon. He not only used the S type and U type surgical instruments but also has documented plastic surgery. However, historians have not been able to assign a definite period to Sushruta. The era of Sushrut is most probably BC and definitely it was prior to 1st century AD.
2. Transplant of internal organs in the human body had begun by the beginning of 3rd century AD.
Sushruta mentioned the plastic surgery in which the flaps of nose skins were used to replace at other parts. We don’t have (most probably) the sources that write about internal transplant
3. The concept of sine of an angle was known in 5th century AD.
This is a correct statement and hints towards Aryabhatta’s Surya Siddhanta. Aryabhata has given the sine and versed sine tables familiar to the students of mathematics.
4. The concept of cyclic quadrilaterals was known in 7th century AD.
Again this is a correct statement and hints towards Brahamgupta , who gave the formula for the area of the cyclic quadrilateral.
Correct answer of this question should be 1, 3 and 4 only.


56. With reference to the history of ancient India, which of the following was/were common to both Buddhism and Jainism?
1. Avoidance of extremities of penance and enjoyment
2. Indifference to the authority of the Vedas
3. Denial of efficacy of rituals
Select the correct answer using the codes given below:
[A]1 only
[B]2 and 3 only
[C]1 and 3 only
[D]1,2 & 3

2 and 3 only


57. Which of the following can be said to be essentially the parts of Inclusive Governance?
1. Permitting the Non-Banking Financial Companies to do banking
2. Establishing effective District Planning Committees in all the districts
3. Increasing the government spending on public health
4. Strengthening the Mid-day Meal Scheme
Choose the correct answer:
[A]1 and 2 only
[B]3 and 4 only
[C]2,3 and 4 only
[D]1,2,3 & 4

2,3 and 4 only
Kindly pay attention to statement 2. You must be aware that in last few years, Government has strengthened the district as the unit of planning in almost all Centrally sponsored programmes. Government has also consciously structured the flagship programmes in a manner that strengthens decentralized management through local institutions. In the Sarva Shiksha Abhiyan and the National Rural Health Mission, District level Plans are being prepared and funded. In the National Rural Employment Guarantee Programme, village panchayat level plans are prepared and aggregated at the District level as a District Plan and funds released to executing agencies which happen to be largely the panchayats. Similarly in the urban areas, under JNNURM, 63 cities have evolved medium term development plans for the cities and have been supported with Central Government funds. Each district planning committee has a crucial role in building a thoughtful vision for its district through a participative and inclusive process. This is a correct statement. Option 3 & 4 are also correct. Correct answer is 2,3 & 4 only.


58. The Nagara, the Dravida and the Vesara are the:
[A]three main racial groups of the Indian subcontinent
[B]three main linguistic divisions into which the languages of India can be classified
[C]three main styles of Indian temple architecture
[D]three main musical Gharanas prevalent in India

three main styles of Indian temple architecture
Most of you know even also about Gadag style which is known for ornate columns :)


59. The Congress ministries resigned in the seven provinces in 1939, because:
[A]the Congress could not form ministries in the other four provinces
[B]emergence of a left wing’ in the Congress made the working of the ministries impossible
[C]there were widespread communal disturbances in their provinces
[D] None of the statements (a), (b) and (e) given above is correct

None (D)
None of them was a reason. The actual reason was that congress, following its policy of non-cooperation in the war effort had called upon the ministries to
resign. For Jinnah , it was a recipe for organizing the DOD on 22.12.1939


60. Which of the following special powers have been conferred on the Rajya Sabha by the Constitution of India?
[A]To change the existing territory of a State and to change the name of a State
[B]To pass a resolution empowering the Parliament to make laws in the State List and to create one or more All India Services
[C]To amend the election procedure of the President and to determine the pension of the President after his/her retirement
[D]To determine the functions of the Election Commission and to determine the number of Election Commissioners

To pass a resolution empowering the Parliament to make laws in the State List and to create one or more All India Services
The second part of the given statement in option B is known to almost all of you. First part of this statement is also correct and is as per the article 249., which says 249 (1) Notwithstanding anything in the foregoing provisions of this Chapter, if the Council of States has declared by resolution supported by not less than two thirds of the members present and voting that it is necessary or expedient in the national interest that Parliament should make laws with respect to any matter enumerated in the State List specified in the resolution, it shall be lawful for Parliament to make laws for the whole or any part of the territory of India with respect to that matter while the resolution remains in force.

    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
