OG13-78 引发对于ambiguity的思考和疑虑

lxskyfly

贴上OG13-78
78 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

想问这个B选项：
OG的解释是：one指代不明；their语法上指代tourist（曼哈顿讲的pronoun的case rule）
但是，我想问的是：
How can we define "ambiguity"?
我的理解是：必须是两个meaning都是make sense的我们才说这是ambiguous的。
这道题的B选项理解起来，个人觉得：明显one可以不精确指代rhinoceroses，而they不可能指代tourists（因为tourists不可能有horns）
所以这道题是不是就不ambiguous了？明显这个理解与OG是opposite了。

真心求指教！谢谢亲们~

哇塞~顶个求前辈们答疑啦！

horn也可以是喇叭号角的意思，乍一看，their horns，their不一定就是指动物，指人也可以。
eg：He honked his horn as he went past
