Proponents of the electric car...

by Maciek » Sat Aug 28, 2010 2:57 pm
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 hate several question in 300 Gmat CR questions but i think i can help you with this CR
in thus argument, the proponent stated that electrical car is good for enviroment because it is free of gas emission and
other conditions such as batery are solved, technique developed >>>> using electric car is perfect for enviroment
the author of this argument reputed the proponent argument and reasoned that electricity for these batteries come from bruning coal which is so so bad for enviroment , thus.....
these all presimise are opposite each other
and A fits that
does it help?

I do not agree with the OA.

IMO E.

Why Proponent of the car will believe in worst consequences. They will always try to deny them.
Electric Cars to replace gasoline cars, reducing the environmental degradation, but at the same these cars draw energy from sources that add to environmental degradation.

So it seems that net effect is zero.

I was bw A & E.
Chose E.

What is wrong with E???

Since each of the three sources produce considerable economic degradation and no where the relativity of the economic degradation caused by these sources is mentioned. That is why left option A.

Please let me know the reasons to chose A over E.


Thanks
