[Critical Reasoning]

试题详情

题目:

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:

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

答案:

A

提问:

请唐塘老师分析一下这道题,我觉得最后一句话说的是直到提取uranium的成本下降了,这个方法不可能商业可行,我感觉这和钱有关,只有C和E是和钱有关都说了cost,麻烦老师分析一下C和E选项哪里错了呢,还有A选项为什么是对的呢,谢谢

提问:

想请问王文静老师,原文我写出的逻辑琏是:cost太高,所以不去海里开采。A选项如果是陆地上uranium没了,的确是应该去海里开采,但这样不会是直接跳过cost,没打到整条逻辑琏吗?我觉得A只打到了conclusion就是不去海里开采这个部分,所以排除掉了。谢谢!

提问:

选了C。 如果回答是,就说明文中to extract uranium from seawater可以用,如果回答不是则相反,这不是评价吗? 为什么老师说这只是陈述了事实?不理解

提问:

还是A/C的对比 老鹰以前说,c的promise是保证,但其实promise还有一个意思是前途,而且这道题一遍读下来就应该知道这里的promise是前途,有希望的意思 而A虽然也可以说和原文相关,但我认为要明显经过大脑推理,不然怎么可能直接有关? 望指正!
