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?

The crux of the argument is that the author is trying to prove the proponents wrong. The author sites situations that will degrade the environment more than the car emissions would. We must not forget here that he sites the 3 situations just to REFUTE the proponents' stand. The author is not concerned about the direct impact of the cars on environment, but is worried about the wrong thinking of the proponents.

(A) will have worse environmental consequences than its proponents may believe -Correct as per our thinking above.
(B) will probably remain less popular than other types of cars -We can't say this from the passage above. The passage is about the environment degradation and not the popularity of cars.
(C) requires that purely technical problems be solved before it can succeed -Irrelevant.
(D) will increase the total level of emissions rather than reduce it -Emissions will be decreased. This is opposite of what is given in the passage.
(E) will not produce a net reduction in environmental degradation -We don't know the net effect. Maybe damming of rivers will be done on a smaller scale than before. We just don't have sufficient information about this option. Nevertheless, the argument is about refuting the proponents and this option doesn't talk about the main point.

Hey Experts,

I don't agree with OA, here.
A is too strong. The author does not say that the electric cars would worsen the environment.
I believe that E is our safest bet.
Hopefully, I am correct. :p

Hi rekhabishop,

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 -- Correct -- This answer choice is not saying that the effects are going to be negative, or that the negative effects will outweigh the positive effects. It's just saying that the positive effects won't be as great as the proponents believe because they forgot to factor in the recharging of the batteries.
(B) will probably remain less popular than other types of cars -- Incorrect -- can't say for sure
(C) requires that purely technical problems be solved before it can succeed -- Irrelevant
(D) will increase the total level of emissions rather than reduce it -- Incorrect -- can't say for sure -- we don't know whether environment degradation due to electric cars will be more than that of other cars
(E) will not produce a net reduction in environmental degradation -- Incorrect -- maybe electric cars will produce a net reduction in environmental degradation but not as much as proponents believe


Sarah claims that peanut butter is good for you. But Sarah failed to consider that peanut butter is high in saturated fat. Therefore, peanut butter is not as healthy as Sarah claims.

It follows a specific pattern. Someone says something, undermining evidence is provided, and a conclusion that says that the person is wrong is suggested.

Same thing in this question. Someone says that the electric car will be good for the environment, undermining evidence is offered, and then we're asked to provide the conclusion that the electric car will not be as good for the environment as some people claim.

Which one of the following most logically completes the argument?

(A) will have worse environmental consequences than its proponents may believe. According to the passage, the "Proponents believe that the electrict car... will result in an abatement of the environmental degradation". As they did not consider the impacts of power plants, we can conclude that the electric car will have worse environmental consequences than its proponents may believe
(B) will probably remain less popular than other types of cars. (can not prove it)
(C) requires that purely technical problems be solved before it can succeed. (can not prove it)
(D) will increase the total level of emissions rather than reduce it. (can not prove it)
(E) will not produce a net reduction in environmental degradation. (44% marked this one. The electric car could actually produce a Net Reduction if the impact of reducing auto emissions > power sources damage. The passage does not provides evidence to compare both impacts and, therefore, you can not conclude that it will not produce a net reduction.

A: CORRECT. The argument suggests that the production of electric cars is not without consequences, specifically those which pose a threat to the environment. These "hidden" ramifications weaken the proponents' conclusion that environmental degradation will be mitigated by switching to electric cars.

B: Irrelevant. We are not concerned with the popularity of electric cars.

C: Fails to address the crux of the argument - that electric cars are not without environmental risks.

D: While this could be possible, the argument neither makes this distinction, nor does it provide evidence to suggest that this may be the case.

E: Like D, we have no way of knowing whether the total level of emissions will rise or fall as a result of increased electric car production, because this comparison is never made. All we know is that electric cars do pose a threat to the environment, albeit indirectly.
