Proponents of the electric car maintain that when the technical problems associated with its battery design are solved, such cars will be widely used and, because they are emission-free, will result in an abatement of the environmental degradation caused by auto emissions. But unless we dam more rivers, the electricity to charge these batteries will come from nuclear or coal-fired power plants. Each of these three power sources produces considerable environmental
damage. Thus, the electric car _______.
Which one of the following most logically completes the argument?
(A) will have worse environmental consequences than its proponents may believe
(B) will probably remain less popular than other types of cars
(C) requires that purely technical problems be solved before it can succeed
(D) will increase the total level of emissions rather than reduce it
(E) will not produce a net reduction in environmental degradation

i go with A...

The author with all his reasoning says that switching to electric cars won’t necessarily reduce environmental damage.

(A) will have worse environmental consequences than its proponents may believe- Seems to be better option- hold.
(B) will probably remain less popular than other types of cars- Info can be true sometime but not always true,
(C) requires that purely technical problems be solved before it can succeed- uses similar terminology as in the passage but presents irrelevant information
(D) will increase the total level of emissions rather than reduce it- Too extreme or out of scope.
(E) will not produce a net reduction in environmental degradation- the author never compares levels of environmental damage. So out..


A is the correct answer. Please post the exact source of the question. Is it a LSAT question??

The term "Each of these three power sources produces considerable environmental damage" in question, did not state will it be higher or lower than that of auto emissions. So how could we say that E-cars will have WORSE impact on environment? How could it be A.

Rather, E stays neutral. Seems E must be the suitable one..

And as for the term "environmental degradation" in option E. Check the premise, which has "will result in an abatement of the environmental degradation". So my take is E.

Experts, please help...

The answer is A. Answer E messes with the wording to try to trap you into the answer. The environmentalists are saying that electric cars eliminate environmental impact. It is definitely still possible to have them not be as great as the environmentalists think, but still be greater than the current system.

Answer A is right for that very reason. It will have worse consequences than the proponents believe, because the proponents believe it will have ZERO consequences. That's why A is right.

This may sound a little fuzzy, but I'll give you the advice that helped me on the LSAT (which I think offers much tougher CR questions than the GMAT). When I was doing the LSAT, I kept missing stupid CR questions until I realized one very important fact. There are no varying degrees of how "good" an answer is on the CR portion. One answer is RIGHT and the other four are WRONG. If you go through the 5 choices and think that two or more "could" be right, then something is wrong. It means that you are missing a key nuance somewhere. Either in the prompt, the question, or the answer choice. When that happens, I usually start by rereading the choices I'm debating between. After that I reread the question, then I reread the prompt (assuming that you haven't spotted the issue along the way). I give that order because I've found that for me personally, it breaks down like this. When I'm in that situation, about 60% of the time my error was in missing a nuance in the choices i'm debating between. About 30% of the time the error is in reading the other choices. And then about 10% of the time it's from the question or the prompt.

Whenever I've tutored people I've told them that this is the single most valuable piece of information I ever figured out. It allowed me to go from consistently making stupid errors, to literally never missing a single CR question. It'll take some time to figure it out, but I encourage you to try it. When you do figure it out you'll feel a million times more confident on CR questions.

Thanks Cart. I will try this. And the answer choices. A seems suitable. As conclusion, if we negate them, it must not hold the argument in any way. Negation just like we do in the assumption questions.
