Contrary to popular belief, video games aren't just for killing an idle Thursday evening, in fact, a variety of recent studies have begun to demonstrate their teaching potential.


A. video games aren't just for killing an idle Thursday evening, in fact, a variety of recent studies have begun to demonstrate

B. video games aren't just to kill an idle Thursday evening, but a variety of recent studies, in fact, have begun to demonstrate

C. video games aren't just for killing an idle Thursday evening; in fact, a variety of recent studies has begun to demonstrate

D. video games aren't just for killing an idle Thursday evening; in fact, a variety of recent studies have begun to demonstrate

E. video games aren't just for killing an idle Thursday evening, and a variety of recent studies have begun in demonstration of


Spoiler: :: Doubt
Can anyone explain to me - a variety of smth is singular or plural? Does it matter whether the noun after of is singular or plural? Trying to understand if there is flaw in my logic, or the OA is wrong.

Yes, the number of "a variety of" depends on what comes after the "of." This particular use of "variety", meaning, "a number of different types," will always be paired with a plural noun after the "of" and so it will always end up being plural. A number of words have a similar property -- including, for instance, the phrase "a number of" in this very sentence! The words that could take either singular OR plural form based on what comes after the "of" are Most, Majority, Some, All, and Half. For instance:

"Most of the people here ARE very clever."
"Most of the window IS already broken."
"Half of the sausages ARE poisonous."
"Half of the water HAS already evaporated."

For "variety," again, you'll always see plural words after "of," unless it's a slightly different meaning, such as:

"A variety of bumblebee is noun to attempt pollination of plastic flowers."

However, fear not; I'm fairly certain there is no such bumblebee in real life.

I think it should be A....I'm confused as well, the second clause is dependent on the first one because of the pronoun "their"

Clauses are "dependent" or "independent" only based on the presence of a main subject and main verb. Here we have "games aren't," a subject and a verb, neither one subordinated by a relative pronoun, preposition, or subordinating conjunction, so they are a Main Subject and a Main Verb. Later, we have "variety ... has begun," another subject and verb, again Main Subject & Verb because they are not subordinated. Two independent clauses require either a semicolon or a coordinating conjunction (FANBOYS).

Furthermore, the verb cannot be "have" in the second clause; the subject is "variety." Remember, anything following a preposition, such as "of," is NEVER the main subject of anything. "recent studies" is the object of "of," not the subject of "have begun."

In terms of pronouns, pronoun ambiguity only has to do with whether or not there is one clear logical antecedent, agreeing in number with the pronoun. An ambiguous pronoun does not make a sentence "dependent." Take, for example, the following paragraph:

"I am really happy with my GMAT tutor. He is professional and knowledgeable and on time and knows a lot about the test. I am thankful for this, because it is a difficult test."

All three sentences are clearly complete sentences and fully independent clauses. "He" in the second sentence refers to "tutor," and "it" in the third refers to "test." Obviously on the GMAT this never happens, since Sentence Correction only tests single sentences. However, the moral of the story is that, in English grammar, pronouns do not have to have their antecedents in the same sentence or clause.

+1D

A comma cannot be used to link two independent clauses. We require a conjunction, full stop or a semi colon after "evening"

Eliminate option A, B and E

Plural "Studies' will take the verb have and not has

C. video games aren‘t just for killing an idle Thursday evening; in fact, a variety of recent studies has begun to demonstrate
D. video games aren‘t just for killing an idle Thursday evening; in fact, a variety of recent studies have begun to demonstrate

:-D

I don't this is a valid question , because the difference between A and D is only the punctuation, GMAT would never differentiate between two sentences based JUST on punctuation.

It's a normal and a less difficult question. Here we are just dealing with punctuation and subject verb errors, whereas other types of questions demands understanding of meaning as well.

In choice A, sentence is run on because we have not placed any proper coordinating conjunction. such error is not just a punctuation error in gmat world: it's serious crime.

I would say don't juxtapose A with D. Just assess whether A is acceptable as such or not. In D punctuation is smartly used to connect two ICs.

If you have just begin with SC then I say your perspective will change with time towards such question in coming days. This question is within limits of tested concepts in GMAT.

:yes

Snippet from article published here http://online.wsj.com/public/resources/ ... S.0706.pdf.

The stylebook’s entry on collective nouns
advises that with words such as variety, number
and total, a rule of thumb is to use a singular
verb when the article the precedes the noun
and a plural verb when the article a is used.

Understand what mentioned above in conjunction with explanation by Adam in above comments.

A variety of bird is very popular (correct)
A variety of birds are in our building (correct)
The variety in languages is rare. (correct)

So there was something more left to learn besides "a number of".

Isn't a "variety of studies" single?
It's not the same as a "number of studies"? or is it?

Yes, "Variety" similar to "bunch" and "a number" => A collection of distinct items.

"A number" is plural. "The number" is singular.

Contrary to popular belief, video games aren‘t just for killing an idle Thursday evening, in fact, a variety of recent studies have begun to demonstrate their teaching potential.

A. video games aren‘t just for killing an idle Thursday evening, in fact, a variety of recent studies have begun to demonstrate - missing ";" before "infact" - which is corrected in option D
B. video games aren‘t just to kill an idle Thursday evening, but a variety of recent studies, in fact, have begun to demonstrate - "but .." "infact..." quite vague
C. video games aren‘t just for killing an idle Thursday evening; in fact, a variety of recent studies has begun to demonstrate - "has" does not agree with plural "games"
D. video games aren‘t just for killing an idle Thursday evening; in fact, a variety of recent studies have begun to demonstrate - CORRECT .. ";" introduced before "in fact" + "have" agrees with "games"
E. video games aren‘t just for killing an idle Thursday evening, and a variety of recent studies have begun in demonstration of - "demonstration" incorrect.. wordy sentence
