题目选项分析

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?

【选项】Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater

选项是否正确?

错在similar to。原文的意思是如果成本不下降,就不合理。E如果改成是否cost small则这个选项可以选

无关
题目说的是extracted from seawater的成本, 拿extract from freshwater的成本来比较并不会对结论产生影响
