Restorers say that if allowed to remove and replace the discolored layer of varnish on the Mona Lisa, the colors Leonardo da Vinci painted nearly five hundred years ago will once again shine through.


A. If ==> No doer
B. if it is
C. if they are
D. when ==> No doer
E. when it is


OA TO FOLLOW

Firs split: S-V agreement.
who is allowed to remove and replace.....? Clearly, the restorers (plural). So B, E are out immediately because of "it".

Second split: Meaning
D and A have same problem, they do not show the doer? Who is allowed to remove and replace? The restorers or someone else?

IMO, C is correct, it tells us the doer-the restorers very clearly.

Waiting for OA.

I think it should be C as some one is required to remove and replace the colours and C provides us with the same ... hence C

A. If
B. if it is
C. if they are
D. when
E. when it is

Can anyone tell me why A is incorrect?
Thanks




A is incorrect because it is unclear as to who is doing the restoration. Also the sentence is ambiguous without 'they are'.

Hi,

In the given sentence it is not clear 'who' is 'allowed to remove....'
Only in option C, it is clearly mentioned 'if they are allowed to remove...' Here 'they' refers back to Restorers.
Hope it is clear. :)

Well, A actually suggests that if colors are allowed to remove and replace the discolored layer of varnish on the Mona Lisa!

The reason for this interpretation is that if allowed to remove and replace the discolored layer of varnish on the Mona Lisa is a past participial phrase and hence, modifies colors.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses Past Participles, their application and examples in significant detail. If you can PM you email-id, I can send you the corresponding section.

My take : C

their should be a doer responsible for replacing and removing the discoloured layer of varnish.

"they" in C clearly refers to 'restorers'

This is a ‘first conditional’ topic with an ‘if clause’ that is in present tense followed by the main clause that is in the simple future. However, the catch is that there should be an ‘if clause’ with a verb and not an ‘if phrase’ with an Ed modifier.
That is the reason, A and D are out. B and E have SV error. Finally, therefore, C remains.

The sentence as written contains a dangling modifier, so beloved of the test makers. The structure is “… if allowed…., the colors…”. In the part of the sentence before the comma there is no mention of who or what is allowed. “Restorers” are allowed. You could correct the sentence by placing “restorers” or a pronoun to refer to them, such as “they”, immediately after the comma. The other way to correct the sentence, as has been done here, is to mention “they” in the first part of the sentence.

Hi,

Could someone help with this one, why could not B - "If it is" be correct answer? I mean, why could not we use "It is" in the same way as "It is easy/difficult/essential to...", in which cases "it" does not really have any antecedent?

Thanks for helping me :)

Grammatically the sentence would be correct, but the meaning would be wrong. The sentence would mean that if it is generally (by law) allowed.
However the original meaning is if the restorers are allowed.

Hi sayantanc2k,

Thanks for your response :-) I have one more question for this, how can we determine which one is the original meaning when both choices are grammatically correct? Is it because in common sense we do not consider the removement and replacement are illegal actions, or are there any other reasons for this?

Thanks for helping me!

I find your query difficult to answer since in general it is not required to use external knowledge to answer a GMAT SC question - let me try to explain in this way:

Consider this sentence:

" If I am allowed to play, our team will win"

The above sentence automatically means that if I am allowed to play, I WILL play.

Now consider the following:

" If it is allowed for me to play, our team would win"

This sentence is slightly awkward because this sentence does not convey the meaning that I would play - it just states that there is no bar against my playing.

I am not sure whether I could explain the difference, but this is the best I could try.

A. If
B. if it is
C. if they are
D. when
E. when it is

beautifull question.

in this phrase: if allowed ... the collors.....through

"if allowed" refer/modifies the subject of main clause, "collors" grammatically. So, this modification is not logic. if we realize the grammatical role of "if allowed", the problem become simple.

we have to realize grammatical role of each phrase in the original sentence before we justify whether these grammatical roles are logic.

we do not need a time relation here. so, "when" is not logic. we need a condition relation. "if ' is better.

B is incorrect because IT doesn't have a clear antecedent...

Why they in (C) can not refer to colour !!

Consider for the time being that they refers to Colour so thee sentence becomes -

Quote:

Does it make sense ? No

Whenever in doubt I try to replace the antecedent with the pronoun to check if it fits in there....

Here , color can not logically be the antecedent , so the correct antecedent must refer to Restorers not colors...

Hope this helps...

Hello GMATNinja,

Can you please explain the difference between A and C? As per the original sentence, we don't know who will remove or replace. Is it ok to change the meaning while we rectify the grammatical error in A?

I don't think the sentence makes any sense at all in (A), for exactly the reason you mention: in (A), it's not clear who is doing the removing and replacing. If anything, it sounds like (A) is literally saying that "the colors" would remove and replace the discolored layer of varnish, and that really doesn't work.

(C) is clear as a bell: "they" has to refer back to "restorers", so now we know exactly who's performing the action.

I hope this helps!
