一道想不明白的逻辑题，大家看看~~

16.A     (27621-!-item-!-188;#058&003223)

 

Most of the world's supply of uranium currently comes from mines.  It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market.  Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.

 

Which of the following would it be most useful to determine in evaluating the argument?

 

(A) Whether the uranium in deposits on land is rapidly being depleted(Y)

(B) Whether most uranium is used near where it is mined(N)

(C) Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater(Y)

(D) Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land(N)

(E) Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater(N)

 

为什么是A而不是C,哪位大虾帮帮忙的，是不是答案错了的

选A.如果没有A选项，C才正确．因为题干是most....

对于提出的论点，A最有效，直接反驳。 C属于可以商量。你可以将此题环境考虑成，是一个经理给CEO提出此建议，CEO的第一反应就是此题的答案。

不好理解的话，尝试将此题换个题目考虑：

大多数的奔驰车都卖给城里的富人。还有一种可能性是卖给深山里的穷人，但是空运的费用和损失远远超过了车的市场价值。因此，除非这部分费用能降下来，这种商业操作才可行。

Which of the following would it be most useful to determine in evaluating the argument?

A:是否法律规定城里的富人不让买奔驰车了

C:是否有用牛车运送而降低费用的可能性

明显，选A嘛。  （注：这里仅举例子，没有瞧不起....的意思）

If the deposits on land are rapidly being depleted, the argument is not convincing for people must obtain U from seawater.

If not ,the argument can make some sense.
