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.

C as well.

I was gonna go with D till I realized that they acknowledge the initial cost in the paragraph.

What's the answer?

I think the answer is B since the discussion deals mostly with economic benefits of using renewable energy. And B cleary indicates that discovering no new deposit in world will drive up the prices of gas,oil and coal which will make the author's explanation right. What is the original answer?

The claim of the utility companies presupposes which of the following?
A The public will embrace the development of wind and solar power. -> out of scope.eliminate
B No new deposits of gas, oil, and coal will be discovered in the near future.-> the new approach is due to fluctuation in availability not due to absence of resources of conventional fuels sources.Even if we get reserves and they get exhausted then this assumption proves wrong.Eliminate.
C Weather patterns are consistent and predictable. -> perfect since the whole article talks about going for renewable energy source due to its stable availability.Hence lets do a negation test : negate this statement and see.Weather is fluctuating and unpredictable then how are we supposed to get sunshine and wind at a stable level to harness energy.argument falls apart then.Hence this i the presupposition in the argument.IMO (C)
D The necessary technology for conversion to wind and solar power is not more expensive than the technology needed to create energy through combustion. -> its already said in passage that initial costs are high .these might be applicable to this clause.hence its not assumption
E Obtaining energy from nonrenewable sources, such as gas, oil and coal, cannot be made less risky. -> its not that obtaining energy from gas,oil and coal is risky.its the sources availabilty .eliminate

I took 3mins to solve it but still went wrong...!!

Did anyone think about b? Frankly but C has not connection with the argument, I some how feel that c is outside the scope. I think B is the best answer.

The utility companies claim that although these sources require significant initial capital investment, they will provide stable energy supplies at low cost. But this is possible only if " Weather patterns are consistent and predictable. ".

Thus C

I don't know if the public embracing the technologies is too relevant. However, "C" surely is.

Could "B" be included in

It wouldn't be prudent to place a windmill/turbine where the wind blows strongly only once a year, or solar panels where there wasn't enough sun on a very consistent basis.

Hi, I would go for D,
because high cost = High risk
If the cost of conversion to solar power > cost of conversion of non renewable sources
Solar Power risk> Non renewable sources risk
If these costs were not presupposed then utilities would not believe that the cost/risk of investing in non renewable sources would be cheaper.

C.

The only way renewable sources of energy are going to be less risky is be if the weather pattern is predictable i.e source of obtaining reneweable sources is stable/predictable.

I chose E as my answer. If you negate option E, it will weaken the argument. Here's how to do it:

e) Obtaining energy from nonrenewable sources, such as gas, oil and coal, CAN be made less risky

by changing from "cannot" to "can", the negated result will weaken the argument big time, so this must be the correct answer.

I say E as well.

Weather patterns were never discussed in the passage, and while this is an assumption/inference Q I feel that the weather patterns are not in line with the scope/intentions of the author.

Just now I got why my answer B is incorrect and C is correct. Hint-reread the question again, it doesnt ask what is the assumption of the argument, rather question is what utility companies assume. In that context C is the best answer.

I freq noticed that many times in the CR, to create tough/tricky question test makers changes the frame of the question from the argument prespective to some third party prespective. Such as-

Head of neigbourhood watch: values of the houses are declines since the opening of the bus stand near the community. People are increasingly unwilling to buy house in the community near to the bus stand.

head of transportation: Values are declining not due to bus stand but due to increasing crime rate in the community. So police should be more active in the community area.

Question.. head of neigbourhood watch must reply which of the following to counter the response of the head of the trasportation?

A> Crime rates are increasing since the opening of the bus stand, specially in the night.
B> Many people are unwilling to buy houses near to the bus stand, reason bus stand often makes more noises in the night.

Hope this will help for people like me, who often misread questions..
