13. Emissions from automobiles that burn gasoline and automobiles that burn diesel fuel are threatening the quality of life on our planet, contaminating both urban air and global atmosphere. Therefore, the only effective way to reduce such emissions is to replace the conventional diesel fuel and gasoline used in automobiles with cleaner-burning fuels, such as methanol, that create fewer emissions.

Which one of the following is an assumption on which the argument depends?

(A) Reducing the use of automobiles would not be a more effective means to reduce automobile emissions than the use of methanol.
(B) There is no fuel other than methanol that is cleaner-burning than both diesel fuel and gasoline.
(C) If given a choice of automobile fuels, automobile owners would not select gasoline over methanol.
(D) Automobile emissions constitute the most serious threat to the global environment.
(E) At any given time there is a direct correlation between the level of urban air pollution and the level of contamination present in the global atmosphere.

E looks best to me.
A is more like an inference.
B.. the argument says "such as methanol".. so this is wrong
C you are replacing the old fuels.. so choice may be out of question.
D. extreme..

Premise:
1) Emissions from autmobiles that burn gasoline/diesel fuel contaminate urban air and global atmosphere
2) Threathen quality of life

Conclusion:
3) ONLY effective solution is to replace diesel/gasoline with cleaner-burning fuels (methanol) that create fewer emmissions.

Which one of the following is an assumption on which the argument depends?

(A) Reducing the use of automobiles would not be a more effective means to reduce automobile emissions than the use of methanol.
- A. shows that only effectiv solution is to replace the type of fuel used.

(B) There is no fuel other than methanol that is cleaner-burning than both diesel fuel and gasoline.
- Out. The use of such as in the conclusion suggests there's more than just methanol that can do the trick

(C) If given a choice of automobile fuels, automobile owners would not select gasoline over methanol.
- not important

(D) Automobile emissions constitute the most serious threat to the global environment.
- does not hold up conclusion

(E) At any given time there is a direct correlation between the level of urban air pollution and the level of contamination present in the global atmosphere.
- out of scope

A it is.

I would go with "D"..

because the argument is " to improve the quality of life , the glabal environment should be improved and in turn we should reduce the emissions from automobiles".

so the assumption is D: Automobile emissions constitute the most serious threat to the global environment

the assumption leads to the conclusion that there is only ONE effective way namely the replacement of fuels. now we have to find the unstated fact that says that there is an even more effective way so that the conclusion falls apart. the negation of A) says that there is an more effective way. therefore the author cannot adhere his conclusion.

Always remember that the assumption is to hold up the conclusion. Without this assumption, the conclusion is no longer true.

Premise + (Assumption) = Conclusion

The OA is A. I fell for B, and realized that the stimulus did not specify methanol as the ONLY or BEST cleaner-burning fuel.

Did the same mistake.. Missed the clue "such as" in the stimulus.
