Lawmaker: Raising taxes is not the only means of reducing government debt. The government's stockpile of helium is worth 25 percent more, at current market prices, than the debt accumulated in acquiring and storing it. Therefore, by selling the helium, the government can not only pay off that debt but reduce its overall debt as well.
Which of the following is an assumption on which the argument depends?
The government has no current need for helium.
Twenty-five percent of the debt the government has accumulated in stockpiling helium is not an insignificant portion of the government's total debt.
It is not in the lawmaker's interest to advocate raising taxes as a means of reducing government debt.
Attempts to sell the government's helium will not depress the market price of helium by more than 25 percent.
The government will not incur any costs in closing its facilities for stockpiling helium.
我开始也选A, 觉得要是需要的话不就不能卖了,但仔细看了下题目,其实问的是argument的assumption, argument是给了前提的:通过卖h,重点是by selling the helium之后的部分,所以和A选项就有点抬杠了,因为已经确定要卖了。
