Reasoning - Commercial flights

by Mani_mba » Fri Oct 10, 2008 7:05 am
Sue: Commercial flights currently contribute more carbon dioxide to the atmosphere in one year than does the whole of Africa. If we want to reduce global warming we need to restrict the number of flights we take.

Dave: Did you know that by taking one inter-continental flight you cause more pollution than you would in twelve months of car travel?

Dave’s response to Sue’s comment serves to

A. reinforce Sue’s contention that flights are a major contributor to increased carbon dioxide levels
B. add more weight to her contention that we should reduce the number of flights we take
C. mitigate the force of her argument by suggesting that there is an alternative approach
D. suggest an alternative that will reduce the effect of pollution
E. question whether she really understands the severity of global warming

Though a not huge fan of A but stll go with A.
Reson being - Suzy talks abt Carbon di oxide and Dave about Pollution.It s not mentioned in the stem that carbondioxide causes pollution.Although it seems to add some weightage to her statement.

B -Dave never says to reduce no.of flights.
C, D - Irrelevant.
E - He never mentioned global warming.

I will go with B

CDE - we can elimintae,

A - He never mentions carbon di oxide levels.

Althought, he does say flight causes a lot of pollution and his response implies that we should reduce the number of flights we take.
