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

ANS : 3

IMO A

B-PRONOUN ERROR
C-UNNECESSARILY WORDY
D-'IF' NOT PREFERRED OVER 'WHETHER'
E-'IF' NOT PREFERRED OVER 'WHETHER'


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.

Answer C:
I don't understand the answer C)
C) whether tourists will continue to visit game parks to see rhinoceroses once the animals' horns have been

I don't understand the "have been trimmed". Since "have been" is the present perfect doesn't that indicate that the action is still ongoing. But if you trim the horns doesn't that mean that the horns have been trimmed in the past and can't be ongoing. Therefore, you should use the verb "are trimmed"? Thanks a lot.

Generally, present perfect indicates actions that started in the past and are still going on.

An alternative use of present perfect is for things that happened in the past but are still true or for things that have ongoing effects.

Some examples:
(1) We have visited Torino in November and found it lovely, though cold.
This doesn't mean we are still visiting, nor that it is still November. It just means that at least once, we did visit in November, and that history is still (and will forever be) true.

(2) I have attached the documents to this cover sheet.
This doesn't mean I am still stapling the papers as I write or as the sentence is read...it just means the documents are still attached.

In your OG example, "have been trimmed" should be interpreted in this way--the zoo employees may not still be trimming the horns, but the horns are still short.

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

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

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

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.
Answer: C

I know that D and E can be rejected because of usage of "if"

Among A, B and C, B and A are rejected for lack of antecedents. I am not looking for the correct answer. I want to understand why "horns have been" is a correct usage. In other words, via is present perfect better than present tense ("are trimmed")

Any help is appreciated.

Yes this is correct. whether > if on gmat

In other words, via is present perfect better than present tense ("are trimmed")The bigger issue here is whose horns - so the possessive "animals' horns" makes it clear whose horns we are talking about. "their" does not have clear antecedent in A and B


Any help is appreciated.



That doesnt answer my question. Can anyone please help me to understand why present perfect works here and not present tense ?

Thanks

The proposal is still in effect (still true) from the past. Hence present perfect.

The difference between ‘have been trimmed’ and ‘are trimmed’ is that trimming is a one –time job and not a daily chore. An event that was done in the past and which or whose effect is still carried through the present will have to be expressed in present perfect, while daily chores will have to be verbed with just present tense. So 'have been trimmed' is the preferred expression

I disagree with gmat1220 with his reasoning here; sorry no-offense. AFAIK here IF is WRONG! There is no question of whether>if. That might be true in general, but I think here IF is just blatantly wrong.

As far as I understood, if is ONLY used for condition and CAN'T be used for QUESTIONS!

Experts, please let me know if you disagree with me.

In this question the OG says that "see" should be " to see" because it is parallel to " to visit", is it possible that in "to see" TO is understood and therefore it isn't shown?

AND in between is making two separate lists i.e whether tourists will continue 1) to visit games parks and 2) to see rhinoceroses after their horns....
whereas they both are dependent as conveyed through the logical meaning i.e to visit games parks to see ..............

So are you saying that with AND between the verbs you cannot use an elipses in the second infinite verb and then you have to write TO VISIT and TO SEE without delete the second TO?!
Thank you for the explanation!!

No i am saying to visit games parks to see( there is no and because to visit and see makes two separate lists whereas the logical meaning conveys one thing, which can be better conveyed using to visit to see

visit and see

is similar to

see and visit

this case is not logical

is must be
visit to see.

we can change the order of do1 and do2, to see which case is correct.

Let us make a 2/3 split on this.

If V/S Whether-

'whether' is used to indicate multiple or single possibilities

'If' is used to indicate a condition


Ex1- Roger cant decide whether to play tennis or football
Ex2- Roger will play if he is fit.

So, A,b,C remain. A and B there is some ambiguity. Choose C
