B cant be the answer. Expenses can be passed on to the customers but that does not indicate that expenses for the company is not increased. It does not HURT the conclusion.

Option B

Conclusion:
Moving from Natural fuel to synthetic fuel will increase the OpEx of the company.

To weaken, find something that says it won't
Option B is the best suited.
A- the report says, it plans to use and IF- so our choice would work on this projection not nullify it, coz we are weakening it

The conclusion is :- Implementation of this plan will almost certainly increase the company's expenses.
E should be the answer. If the long-needed conservation procedures becomes practical and compensates for the higher cost of the fuels , then the implementation of this plan of introducing synthetic fuels may NOT increase the company's expenses.
E is the weakener and should be the answer.
Option C is close but not strong enough.­ MartyMurray
E clearly agreed that the expense will increase just that it will be compensated for by something else. However the conclusion we intend to weaken is that expenses will increase...So I sort of don't think E does the job here...C does it better by unambiguously state that the company has ability to produce at a lower cost given its structure.

In its report for the quarter just ending, Company X announces that in some of its manufacturing processes it plans to begin converting from conventional fuels like oil and natural gas, which are rapidly becoming scarce, to synthetic fuels currently under development in the company's laboratories in Europe and the American far west. Implementation of this plan will almost certainly increase the company's expenses, since even if the synthetic fuels are rendered practical for use they can be expected to cost considerably more than conventional fuels.

Which of the following, if true, casts the most doubt on the argument above?

(A) Company X's synthetic fuels will not be ready for use in its manufacturing processes for at least a decade.

(B) Whatever increased expenses accrue from the development and use of synthetic fuels can and will be passed on to consumers of Company X's products.

(C) Company X's manufacturing processes can be adapted to the use of synthetic fuels at little or no expense.

(D) In time, the raw materials used to produce Company X's synthetic fuels will become as scarce as oil and natural gas.

(E) Long-needed conservation procedures will become practical when synthetic fuels are introduced and will compensate for the higher cost of the fuels.

This had to be the right answer as this gives a positive reason for adoption of synthetic fuels and would cast a shadow on the argument against the entire plan.

­I don't think B is the answer since that will affect the companies profits and not the expenditure. The expenditure will still be on the rise.­

(E). Casts the most doubt on the argument, by providing a scenario, where the expected increase in expenses might be mitigated by new conservation procedures, thus questioning the conclusion that expenses will almost certainly increase.­

KAPLAN OFFICIAL EXPLANATION



(E) is correct because it shows how the company will save money; using the new fuels will let them use conservation measures which will compensate for the increased costs.

(A) may show a downside of switching to the new fuels, but the argument isn't that the plan shouldn't be adopted, just that it will increase expenses, so this doesn't weaken it.

(B) may be tempting, but showing that the expenses will be passed on to the consumer doesn't change the fact that the expenses will exist.

(C) is irrelevant; the fact that adapting the processes won't cost much doesn't help, since the fuels themselves are what will cause the increased expenses.

(D) does not show how synthetic fuels would be any less costly now. In fact, if the raw materials for those fuels do become more scarce over time, then the costs could actually get even higher, just adding more support to the author's claim.

TAKEAWAY: When an author says something will cost more, weaken it by pointing out that it may save money in other ways.­
