Ok , here is what i feel

1 "their" is ambiguous ; pointing to rhino or people ??
2 same "their"
3 This makes sense (though wordy but conveys the meaning 'right')
4 ' If ' shud not be used
5 same as 4

Even i went for A...but correct answer as per 1000 SC is C.
I am not able to make out why do we need past perfect "have been" ?

This is the OG question. You can get better explanation.
C is correct.
Reason: Pronoun should correctly identify corresponding Noun. Here "their" is not clear whether it is referring to animals or visitors.

Is "their" ambiguous here since logically people can't have "horns" .I am confused should we think "logically" while making out pronoun referents ?

Shouldnt the answer have IF becuase it is describing a hypothetical situation and not one with alternatives(whether)?

Thx

I Will also go with A..

C & D are out because they USE IF.
B is also out because here to see one once their horns to see one(singular) once their(plural) is wrong.
C is wordy So A is the right answer...

'have been' is present perfect and not past perfect. 'Had been' is past perfect.

C should be absolutely correct, A has a pronoun error.

Alternative 1 - whether tourists will come

Alternative 2 - whether tourists will not come

There is no hypothetical situation mentioned in the question.

I answered it in another way: The question to me is much rather whether "tourists come to the park and see rhinoceroses" or whether "tourists come to the park to see rhinoceroses". I think this answer (C) conveys the message much better and resolves the pronoun problem (their) as well.

This is good thinking. For example, "I went to the store and saw Mary" means I had no intention of seeing her and she happened to be there. "I went to the store to see Mary" means I knew Mary would be at the store and the purpose of my trip was to see her.
In our sentence the question is whether tourists will make a trip with the purpose of seeing the rhinos (not if the tourists will accidentally see rhinos). A and D - crossed off.

Step 2: As mentioned before, the pronoun "their" is a little ambiguous, as is the use of "one" in B and E. "One" needs to be much clearer. Here it could refer to "one" rhino or "one" horn. B and E - crossed off.

D and E are out .

A and B have pronoun error as discussed which is not in C.
But i would like add one more point that C uses the correct verb tense(Present perfect)
"whether tourists will ....... once the animals’ horns have been" i.e if the proposal goes thru..the horns of tha animals will be trimmed. So the EFFECT remains.Pls refer MGMAT SC if you dont understand EFFECT analysis here.

The methodical steps to this issue may be:
1. This is question of deciding on a dilemma. Hence the conditional ‘if’ is irrelevant; dump D and E.
2. “To see” denotes the purpose of a visit and better than ‘and see’. Hence A is out.
3. To see “one” after “their” horns: the subject - pronoun number mismatch is too glaring.
4. C is the remainder
IMO, the difference in the use of present perfect or present tense is rather too thin. Both are acceptable in formal writing I suppose. As in this case: - I wonder whether I can enjoy bones once my teeth are broken - is as good as - I wonder whether I can enjoy bones once my teeth have been broken - nothing much to choose from. But this is just my feeling.

As per OG The verb following after should
be the present-perfect have been trimmed to reflect
that the trimming must occur before the tourists
arrive.

But already the time maker after is there, so why is it necessary to use present perfect tense here

Also what is the basic difference in using whether and if? When to use if and when to use whether?

Hi Ashish,

Time markers such as "before" and "after" should be used to substitute actions only when the past perfect tense is used. This rule does not apply to the present perfect tense, since this tense doesn't need two actions. The present perfect tense refers to an action that started in the past and has continued into the present. It can stand on its own without reference to any other action.

"If" should be used in "if-then" contexts: i.e., the conditional use. E.g. 'If X happens, Y will happen'. 'Whether' is used when there is a choice between two things. E.g. It is unclear whether the company will increase production. Meaning: the company may increase production, or it may not.

I hope this helps!

Regards,
Meghna
