As of this morning, none of my friends have been able to solve the puzzle contained in last week's newspaper.


(A) none of my friends have been able to solve

"none of my friends" is singular subject and requires singular verb. "have" is INCORRECT

(B) none of my friends was able to solve

"As of this morning" indicates an event that is continuing in the past. Hence the use of "was" is INCORRECT

(C) not one of my friends has yet been able to solve

"none of my friends" sounds better than "not one of my friends". "yet" changes the meaning. INCORRECT

(D) none of my friends has been able to solve

singular subject and singular verb "has"

(E) nobody among my friends have solved

"nobody" is singular and "have" is plural. INCORRECT

Hence option D

According to Oxford American Dictionary:

USAGE It is sometimes held that none can take only a singular verb, never a plural verb: : none of them is coming tonight, rather than : none of them are coming tonight. There is little justification, historical or grammatical, for this view. None is descended from Old English nān, meaning ‘not one,’ and has been used for around a thousand years with both a singular and a plural verb, depending on the context and the emphasis needed.

So it is a somewhat controversial issue, and therefore I doubt that GMAT would make this the "only" error on a question.

Option D is correct. Option A and E are not correct as plural verb "have" is used. In option B, usage of tense is wrong. With the phrase "As of this morning" past tense doesn't go well. In option "yet" is redundant. Hence it is option D.

Please refer to the below excerpt from MGMAT SC
=====================================================

There are, however, 5 indefinite pronouns that can be either singular or plural depending on the context
of the sentence. You can remember these 5 by the acronym SANAM.
THE SANAM PRONOUNS: Some, Any, None, All, More/Most
How can you tell if these pronouns are singular or plural? Think about meaning, and look at the Of
phrase which usually follows the pronoun. You may recall that you are generally supposed to ignore O f
prepositional phrases (since they are misleading middlemen). But with the SANAM pronouns, the noun
object of the Of -phrase can help you determine the number of the subject.
Right: Some of the money WAS stolen from my wallet. (money is singular)
Right: Some of the documents WERE stolen from the bank, {documents is plural)
Don’t apply the Of phrase mechanically. None 0f and any of followed by a plural noun can be singular.
Right: Any of these women IS a suitable candidate for marriage to my son.
You are referring to just one woman at a time. Since the usage of these pronouns is hotly contested
among experts, the GMAT is unlikely to test controversial cases.
Note that "not one" is always singular: Not one of my friends IS here this weekend.

(D) none of my friends has been able to solve

KAPLAN OFFICIAL EXPLANATION:



So what's the answer to the question above? It's (D), and here's why:

None is singular (like every or everyone) and have been is plural. Singular subjects need singular verbs, so we can immediately eliminate (A) and (E). As for (B), Has been beats was. Even though they're both singular, there is no valid reason to replace the original verb. Has been is in the perfect tense and, as such, describes an action that began in the past and continues into the present. The beginning of the sentence (As of this morning) indicates that we're dealing with this sort of situation: the friends have been working on the puzzle, still seem to be working on the puzzle, and are not able to solve it. Was describes an action that took place entirely in the past and therefore is inappropriate considering the beginning of the sentence. So much for (B). As for (C), there's nothing wrong with None that would require its substitution with Nor one (and none is an elision of not one anyway). That leaves (D).

An 800 test taker knows that unnecessary changes are incorrect changes when it comes to Sentence Correction questions. He doesn't fix any part of the sentence unless it's broken.
