21. A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is whether tourists will continue to visit game parks and see rhinoceroses after their horns are trimmed.
(A) whether tourists will continue to visit game parks and see rhinoceroses after their horns are
(B) whether tourists will continue to visit game parks to see one once their horns are
(C) whether tourists will continue to visit game parks to see rhinoceroses once the animals’ horns have been
(D) if tourists will continue to visit game parks and see rhinoceroses once the animals’ horns are
(E) if tourists will continue to visit game parks to see one after the animals’ horns have been
说a没有c的表达好，是个什么道理呢？

their 指代不清

此題說their指代不清，可是很明顯的their是指代rhinoceros。人怎麼有角呢？OG中有許多題是這麼解釋的，就是常識題呀！請指教！

a.中的are时态有没有错？一定要用c.中的have been吗？

在此处两者可否互换？两者用法有何区别？

The present perfect tense form, have been ,has to be used in order to show the correct sequence of the actions.

Normally the present perfect tense and the present tense are not exchangeable in formal English.

那是不是这个地方就一定要用完成时呢？

即：是不是once it is done不如once it has been done好？

我也感觉这道题的重点不是在考代词指代，而是在考时态。

1.and see 不能清楚表达visit的目的,应该用动词不定式to see表目的

2.trim动作发生在visit之前所以应用完成时

这里，are trimmed和have been trimmed有什么区别？难道二者不都是说角已然没了吗？

A里面their有歧义，GMAC认为指代游客，C没有歧义，最佳
