Analysis of UPSC Civil Services 2010 (GS Paper) : Part -II

The million-dollar question is what would be cut off for GS paper. In my view the candidates who could attempt 70-80 questions with about 62-65 correct answers or could attempt 80-90 questions with 70-73 correct answers should be able to sail through and should start concentrating on Mains Preparation. Those who are confident about their optional should not worry of GS paper because cut off for GS is not going to be very high this year. I have honestly tried to solve these questions by giving reference / explanation, I may need correction in few questions and we all should be open to discussions / corrections.
21.Widespread resistance of malarial parasite to drugs like chloroquine has prompted attempts to develop a malarial vaccine to combat malaria. Why is it difficult to develop an effective malaria vaccine ?
(a) Malaria is caused by several species of Plasmodium
(b) Man does not develop, immunity to malaria during natural infection
(c) Vaccines can be developed only against bacteria
(d) Man is only an intermediate host and not the definitive host

For most infectious diseases for which effective vaccines are available , a single infection confers long standing protective immunity. A person who had measles does not develop measles again. This type of sterile protective immunity does not exist for malaria. So man lacks naturally acquired protective immunity against the plasmodium or other malarial parasites. Plasmodium has its own ingenious way of avoiding hosts’ immune response and that is why it has been very difficult. RTS,S is one of the malarial vaccine candidates.

Correct answer: B

22. Consider the following statements:
1. The boundaries of a National Park are defined by legislation.
2. A Biosphere Reserve is declared to conserve a few specific species of flora and fauna.
3. In a Wildlife Sanctuary, limited ‘ biotic interference is permitted.
Which of the statements given above is /are correct ?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

Lets discuss this tricky question:
Statement 2 is correct: A biosphere reserve is a unique concept, which includes one, or more protected areas and surrounding lands that are managed to combine both conservation and sustainable use of natural resources. In India 13 states in have Biosphere Reserves and the funds allocated to them is utilized to monitor and promote bio-diversity conservation through surveys and assessment of flora and fauna. Basically Biosphere reserves are to protect larger areas of natural habitat, and often include one or more national parks and/or preserves, along buffer zones that are open to some economic uses as per the IUCN Category V.

Statement 3 is correct:
The difference between a national park and a sanctuary is that no human activity is allowed inside a national park, while limited activities are permitted within the sanctuary.

Now lets discuss statement 1:
please refer to The Indian Wildlife (Protection) Act, 1972, amended 1993, CHAPTER IV, 35.

Declaration of National Parks. Ref
1. Whenever it appears to the State Government that an area, whether within a sanctuary or not, is, by reason of its ecological, faunal, floral, geomorphological, or zoological association or importance, needed to be constituted as a National Park for the purpose of protecting& propagating or developing wildlife therein or its environment, it may, by notification, declare its intention to constitute such area as a National Park.

3. Where any area is intended to be declared as a National Park, the provisions of Sec. [1219 to 26-A (both inclusive except clause (c) of sub-section (2) of section 24)] shall, as far as may be, apply to the investigation and determination of claims and extinguishment of rights, in relation to any land in such area as they apply to the said matters in relation to any land in a sanctuary.

4. When the following events have occurred, namely

(a) the period for preferring claims has elapsed, and all claims, if any, made in relation to any land in an area intended to be declared as a National Park, have been disposed of by the State Government, and

(b) all rights in respect of lands proposed to be included in the National Park have become vested in the State Government the State Government shall publish a notification specifying the limits of the area which shall be comprised within the National Park and declare that the said area shall be a National Park on and from such date as may be specified in the notification.

5. No alteration of the boundaries of a National Park shall be made except on a resolution passed by the Legislature of the State.

The fifth para holds the first statement in the question correct
Correct answer D.
23. A pesticide which is a chlorinated hydrocarbon is sprayed on a food crop. The food chain is: Food crop – Rat -Snake – Hawk. In this food chain, the highest concentration of the pesticide would accumulate in which one of the following?
(a) Food crop
(b) Rat
(c) Snake
(d) Hawk
The examiner uses the term “chlorinated hydrocarbon” instead of a simply using DDT which is dichlorodiphenyltrichloroethane, a persistent well-known synthetic pesticide with a long controversial history. The question just wants to know whether, you are aware of the concept of Bio Magnification. Bio Magnification is also known as bioamplification. Simply, it states that some pesticides are biomagnified. They reach higher and higher levels with each successive step in the food chain. Small amounts of pesticides are absorbed by the plants and they get transferred to increased concentration in fishes, birds, animals and man. Indian White-rumped Vulture (we call it a Gidhh in Rajasthan) getting disappeared due to the same phenomena.

Correct answer: D (Hawk)

Statement 2. an NBFC cannot accept demand deposits; statement 2 is correct.

Correct Answer B : Two only.

26. Which one of the following was not stipulated in the Fiscal Responsibility and Budget Management Act, 2003 ?
(a) Elimination of revenue deficit by the end of the fiscal year 2007-08
(b) Non-borrowing by the central government from Reserve Bank of India except under certain circumstances
(c) Elimination of primary deficit by the end of the fiscal year 2008-09
(d) Fixing government guarantees in any financial year as a percentage of GDP
Please refer tThe FRBM Act 2003 ref
FRBM Act 2003:
4. (1): The central government shall take appropriate measures to reduce the fiscal deficit and revenue deficit so as to eliminate the revenue deficit by the 31st march 2008. (statement 1 stipulated)
(2): The central government shall by rules made by it specify-
(a): the annual targets for reduction of fiscal deficit and revenue deficit during the period beginning with commencement of this act and ending on March 31, 2008

2 (b) the government shall specify the annual targets of assuming contingent liabilities in the form of guarantees and the total liabilities as a percentage of GDP (statement d was stipulated)

5(1): the central government will not borrow from the RBI excpet under certain circumstances.
Here I would like to mention that as per the target, revenue deficit, which is revenue expenditure minus revenue receipts, had to be reduced to nil in five years beginning 2004-05. Each year, the government was required to reduce the revenue deficit by 0.5% of the GDP. The fiscal deficit was required to be reduced to 3% of the GDP by 2008-09. It would mean reduction of fiscal deficit by 0.3 % of GDP every year. Under the Fiscal Responsibility and Budget Management Act, the Centre should have eliminated the revenue deficit and brought down the fiscal deficit to 3 per cent of gross domestic product by March 2008. This target was extended by a year. Then, due to the global economic crisis, the government decided to suspend implementation of the FRBMA. Please read in this post para 6 titled Fiscal Deficit Problems

Correct Answer: C there was no stipulation of primary deficit to be brought to zero in the act.

38. Consider the following:
1. Oxides of Hydrogen
2. Oxides of Nitrogen
3. Oxides of Sulphur
Which of the above causes/cause acid rain ?
(a) 1 and 2 only (b) 3 only (c) 2 and 3 only (d) 1, 2 and 3

Again this is a tricky question. Oxide of Hydrogen is water and Hydrogen Oxide is the simple and systematic name of water. The acid rain is basically a result of reactions of Oxides of Hydrogen, Nitrogen and Sulphur.
The Acid rain is acid rain because of the presence of Nitric acid and Sulphuric Acid.
Water Reacts with CO2 in the atmosphere to form carbonic acid (the one which we enjoy in Cola drinks) . It is a weak acid and partially gets dissociated in the following Ions.
CO2 + H2O <----> H2CO3 <-----> H+ + HCO3-

Oxide of Nitrogen that is Nitric Oxide reacts with oxide of Hydrogen that is water to give rise to Nitric acid as follows:
2NO2 + H2O —-> HNO2 + HNO3

Oxide of sulphur reacts with oxide of Hydrogen (water) to form H2SO3 known as a unstable sulphurous acid.
SO2 + H2O <-----> H2SO3

The Oxide of Sulphur reacts with atmospheric Oxygen to also create sulphur trioxide (SO3) which is again unstable.
2SO2 + O2 —–> 2SO3

This unstable Sulphur Trioxide reacts with Oxide of water to get Sulphuric acid.

SO3 + H2O —–> H2SO4

This means acid rain is a result of reactions of oxides of Hydrogen. Nitrogen and Sulphur.
Correct Answer: D (all 1, 2,3 )

39. Six persons M, N, O, P, Q and R are sitting in two rows, three in each. Q is not at the end of any row. P is second to the left of R, O is the neighbour of Q and is sitting diagonally opposite to P. N is the neighbour of R. On the basis of above information, who is facing N ?

    Q. 38 Acid Rain answer is c only

    The most important gas which leads to acidification is sulfur dioxide. Emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulfur containing compound [Source: wiki]

    The acids formed are h2so4 and hno3 respectively, but there is no hint of hcl in acid rain

    Speed of train is 60km/h
    therefore it means 60km/h =60km/60 min=1km/min
    this means train has travelled in 2 min 2km (2* 1km/min)

    We know total distance travelled is 1.5 + z (length of train taken as z)
    Therefore 1.5 + z = 2
    z = 2-1.5
    = .5km
    = 500m

    Q 33
    Speed of train is 60km/h
    And acc. to question train travels the 1.5 km long tunnel in 2 minutes.
    just apply ur mind when train enters the tunnel the first its engine will be enter and at the exit time last coach will be there.
    Therefore total distance travelled in 2 minutes is (2L+1.5)Km
    where L is the length of train
    As we know


    here we convert min into hrs to maintain the units
    after solving
    L=1/4 km
    covert it into meter by multiply with 1000
    L=250 m
    Therefore ans (a) is correct

    Another Style to solve question no. 33

    As we know train speed is 60km/hr
    Time to cross a tunnel is 2 min = 1/30 hrs
    Total distance travel in (1/30 hrs) is
    Speed * Time
    Length of tunnel is 1.5 km
    Remaining Distance is 0.5km = 500 m
    just apply ur mind when train enters the tunnel the first its engine will be enter and at the exit time last coach will be there.
    Therefore 2L=500
    L=250 m

    Answer (a) is correct
