Businesses are suffering because of a lack of money available for development loans. To help businesses, the
government plans to modify the income-tax structure in order to induce individual taxpayers to put a larger
portion of their incomes into retirement savings accounts, because as more money is deposited in such
accounts, more money becomes available to borrowers.
Which of the following, if true, raises the most serious doubt regarding the effectiveness of the government's
plan to increase the amount of money available for development loans for businesses?
(A) When levels of personal retirement savings increase, consumer borrowing always increases
correspondingly.
(8) The increased tax revenue the government would receive as a result of business expansion would not
offset the loss in revenue from personal income taxes during the first year of the plan.
(e) Even with tax incentives, some people will choose not to increase their levels of retirement savings.
(D) Bankers generally will not continue to lend money to businesses whose prospective earnings are
insufficient to meet their loan repayment schedules.
(E) The modified tax structure would give all taxpayers, regardless of their incomes, the same tax savings for
a given increase in their retirement savings.

Please some one explain this...as i am not convinced with the explanation from OG

Still waiting for some more replies before posting OA

Yes A it is...

Also, A is just the prephased of last sentence of the argument.

agreed with seekmba
if people would put more money in retirement saving plan they eventualy end up very less personal saving hence they could become borrowers themselves, and this could frustrate govt's plan, hence the nas must be A

Plan of government is to increase the money so that it can meet the loan amount required. Therefore, govt thinking to modify the tax structure to get the more money collected .
But, if due to this plan, if money demanded by the business/consumer also increases, then this plan will not work

Hence A

I'm not saying that A is wrong. But the explanation still doesn't rule C out.

As per my response above, The plan would fail because people won't put more money than is currently in a retirement savings account in spite of changes to the tax structure.

I think the reason that OG quotes is not good enough to rule out option C.

Expert...

Please help with this OA.

I still don't understand why OA is A.

As my undertanding. "Some" is pretty close to the "few", perhaps 30%. Clearly, "some" doesn't represnting "most". Furthermore, (C) gives us some weaken but not strong enough compare with (A). Remeber, we have to determine which one is "most weaken" the argument. In other words, partially weaken is not a correct answer(same to the strengthen question). Thus, C out and A is the best!

I got better explaination from another site, but not sure if I can post link here.
