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 the total amount of uranium in seawater is significantly greater than the total amount of uranium on land

选项是否正确?

易混淆。
cost减少→viable
有副词修饰 significantly
land的够用,就算sea再多,也没关系
