Some scientists have been critical of the laboratory tests conducted by the Federal Drug Administration on the grounds that the amounts of suspected carcinogens fed to animals far exceeds those that humans could consume

A. far exceeds those that humans could consume

B. exceeds by far those humans can consume

C. far exceeds those humans are able to consume

D. exceed by far those able to be consumed by humans

E. far exceed those that humans could consume

答案为E，我觉得C 比较好～～是时态问题么？？我觉得原句时态就不太多吧

个人感觉 COULD 一直都是优于BE ABLE TO的选项的。。

好像COULD和BE ABLE TO的意思有区别。。

Could 就是 有能力做什么。。

BE ABLE TO是 通过学习 努力以后能做什么什么。。

谢谢～～有没有更好的解释呢，比如时态，和更肯定的could 和be able to 在这里的区别～～

the amounts of suspected carcinogens fed to animals far exceeds those that humans could consume

the amounts of suspected carcinogens + 复数，排除ABC,

E,单数，形容词修饰名词，简洁,被动改主动。

不需要从意思上（能力还是可能性）加以区分吗，只要注意时态看哪个更合适，又没有明显错误就行
