提问:

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 B.Whether most uranium is used near where it is mined C.Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater D.Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land E.Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater

提问:

请徐小梅老师答疑:对B来说是inversely proportional不一定是m/B的形式吧,也有可能是-mB(m>0)的形式,为什么一定要写成两个变量相乘的形式而不是两个变量相加的形式?

提问:

这个题当时在C和E犹豫了蛮久,而且我看OG答案里也说C might somewhat help to explain。所以这种选项要去判断呢?怎么能准确的定位到正确答案呢? 希望张老师回答一下
