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 to see rhinoceroses once the animals' horns have been trimmed

A  proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is if tourists will continue to visit game parks and see rhinoceroses once the animals' horns are trimmed

上面一个是答案,下面一个是我选的。答案的解释是， and see应该是 and  to see, 然后once 后面应该用have been
我疑惑的是句子的主语都是游客，所以and to see应该可以省略to(to visit and see), 不是致命问题啊，后面的 once 后面要加have been也是完全没有听过，请解释一下，是固定的形式吗？

no
meaning is tested here

you should not separate the purpose(see rhino） from the action（go to the park），which create two individual actions that render sentence a relatively inferior meaning.

similar example

it is better to say that you open the computer to play games than to say that you open the computer and play games

just spend a min to think of the difference here~

楼上是正解~ see是visit的目的，应该用visit to see，不应该用visit and see，后者是两个相互平行的动作

once可以是连词，那连词的话自然是连接句子，那理论上后面用什么时态都可以。。你的答案还有个问题是if没有“是否”的意思只有“如果”的意思

斑竹，还是有个问题。

为什么这里要用have been呢?

FROM MANHATTAN:
I think the use of "have been trimmed" rather than simple past tense "were trimmed" is to indicate that not only were the horns trimmed in the past but the animal tenders will also continue to trim the horns in the present to keep the horns short. Otherwise, after one trimming the horns could grow back to their previous size, and this growth would cause the animals to look the same as they did in the past. Thus, there would not need to be a concern about the impact of short horns on park attendance. This sentence appears to be describing a plan to trim the horns regularly to keep them short; thus, the trimming is ongoing.
