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

我想问的是whether和if在这道题的用法有什么不同，还有就是如果E把one换成rhinoceroses可否选E呢

whether表“是/否”

if不仅可以表“是/否”，还能引导条件状语从句，因此存在歧义。

当表“是/否”的情况时，选whether而不是if

记的在gmat语法中if只能表条件 不能表是否

正解，只有是否两个可能时，用whether引导条件状语从句
