CSAT Paper I 2011 Analysis

1. In the Union Budget 2011-12, a full exemption from the basic customs duty was extended to the bio-based asphalt (bioasphalt). What is the importance of this material?

2. Bioasphalt can be made from non- renewable resources.

... 3. Bioasphalt can be made from organic waste materials.

4. It is eco-friendly to use bioasphalt for surfacing of the roads.

Which of the statements given above are correct?

(a) 1,2 and 3 only

(b) 1,3 and 4 only

(c) 2 and 4 only

(d) 1,2,3 and 4


  1. - Answer is B
    - Question came from General issues on Environmental Econoly (daily life linked Chemistry section)
    -Its amazing that the issue of Asphalt is taken from Union Budget!
    - So ecological questions can be traced from anywhere! Not only from Science related magazines, readymade notes..
    - Thing is to observe why they have given importance.
    - Bioasphalt is an asphalt alternative made from non-petroleum based renewable resources.
    ‎- Bioasphalt is made from renewable sources only. So Option 1 is right, its made from renewable resources so Option 2 which says 'can be made from non-renewable resources ' is wrong, Option 3 is right bioasphalt got its importance since it is made from organic waste..and option 4 is right since bio asphalts eco-friendlyness made it in news and union budget to sanction full exemption from custom duty..So Option 1, 3, 4 is right so answer B is right.
    But the time taken to read the whole thing clearly & to come for the final conclusion answer keeping the tricking in optional choices is 5-6 mins. Sometimes it takes 10 mins also without yielding any answer so be careful attending such question and much careful preparing for such question.
    Logical thinking -
    Whenever we see such questions with 4 statements we can see the examiner played in framing the question and in twisting the simple thing using complex wordings.
    - one who is aware of this & hold over english usage can handle this knowing little info.
    - Many aspirants who dont know abc of this issue, go through the a, b, c and d option and try to figure out the indirect answer in that & this is not applied to all question. But many time it works..& saves time.
