would go for C

E not an assumption as after negation the argument is not weakened. if non renewable sources can be made less risky, it doesnt mean the renewable sources will be risky.

The answer is C.

The reason why E isn't the answer is because: Even if the availability of NRR can be made less risky (stmt negation), it still does not tell us whether it will less or more risky than that of RR.

Hi Madhur, when you post questions on a forum, you should take the ownership of posting the OA too.
Otherwise, people end up getting confused and are never sure of a definite answer.
madhur_ahuja wrote:In response to the increasing cost of producing energy through traditional means, such as combustion, many utility companies have begun investing in renewable energy sources, chiefly wind and solar power, hoping someday to rely on them completely and thus lower energy costs. The utility companies claim that although these sources require significant initial capital investment, they will provide stable energy supplies at low cost. As a result, these sources will be less risky for the utilities than nonrenewable sources, such as gas, oil, and coal, whose prices can fluctuate dramatically according to availability.

The claim of the utility companies presupposes which of the following?
1 The public will embrace the development of wind and solar power.
2 No new deposits of gas, oil, and coal will be discovered in the near future.
3 Weather patterns are consistent and predictable.
4 The necessary technology for conversion to wind and solar power is not more expensive than the technology needed to create energy through combustion.
5 Obtaining energy from nonrenewable sources, such as gas, oil and coal, cannot be made less risky.

I wanted to end the suspense for you guys and I found that this is a MGMAT question. The official answer is C.

Here is the link to that discussion.

Let me know if you have any questions after reading this discussion.

OA is C.

Seriously, you can believe me. I looked it up and I found that this is an MGMAT problem and the Answer is C.

Ket has given a very good explanation in a post above (back in 2009!). The analysis is right on.

There is also some discussion as to the assumptions required by this answer choice. There was a discussion of this problem halfway though this thread:

IMO D

The answer should say something about cost of renewable energy not being low. D does that perfectly.

So, the reason I chose B is
whose prices can fluctuate dramatically according to availability.
We have a clear statement in the conclusion which depends on the availability of non-renewable sources.


I did not choose C because even though we know it through common knowledge, the passage did not mention how important a role the weather would play w.r.t harnessing renewable energy.

Any views?

Also, I find many MGMAT CR questions with debatable OA. Would such appear on the GMAT ( what I mean is 2 partially correct answers)
Whether you think you can or can't, you're right.
