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?

a. The public will embrace the development of wind and solar power.
b. No new deposits of gas, oil, and coal will be discovered in the near future.
c. Weather patterns are consistent and predictable.
d. The necessary technology for conversion to wind and solar power is not more expensive than the technology needed to create energy through combustion.
e. Obtaining energy from nonrenewable sources, such as gas, oil and coal, cannot be made less risky.

Please help me answer this question.

The conclusion is that the new sources will be less risky.

The assumption is that the new sources will be less risky because availability of these sources will be consistent.

C directly states the assumption.

You can prove it by negating C.

Weather patterns are not consistent and not predictable. Could author possibly conclude that the new sources would be less risky if weather patterns were not consistent or predictable?

Hope that helps.

what is the OA? Will someone pl. provide soe additional comments?

I opted for E as well. But the OA is C.

I think I made a mistake in consider the "less risky" phrase of option E as "lesses than in the case of renewable resources". This conclusion can't be drawn assertively.Hence C seems to be a better option.

Yep, It should be C

If you by chance went with B, then that is not an assumption as it is already covered in premise that "and coal, whose prices can fluctuate dramatically according to availability"

Pl. explain.....

I should be C because from the last line its clear that company doesnt want to use nonrenewable because of their availability, it means that company assumes that the supply or availability of renewable products are consistent

for me E is not the right ans because its not the assumption its already given in the premises in last two lines

The whole argument is about "stable" energy, not about expensive/less risky.
C is clearly an assumption for stable energy.

I picked E as well at first. But when you just isolate "The company's claim" and look for the assumption on which it should be based, then the C will fit a lot better.
