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.

[Reveal] 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.

The issue must be between A or D...

A and D differ by the use of semi colon here.

I am confused regarding the use of semicolon here:

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

I understand that semicolon is used to connect two independent clauses. But the sentence after semicolon does not looks like a independent clause "their teaching potential" . " their" is unclear.

Please clarify.

My answer would also be D.

I would say that A is a run-on sentence. The comma is not sufficient to connect the two main clauses; however, a semicolon solve this problem.

I would also say that "Video games" is clearly the subject in the first clause making "their" unambiguous. What else could be the antecedent?

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"

The independence of clauses in ; usage allows use of pronouns. Think about it, if there were no correlation between the two clauses, the punctuation may well be a . (fullstop/period). Presence of pronouns should not be considered while deciding independence of clauses.

BOOKMARKED
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.

Tricky one.
I shortlisted A and D. Going with D as I think ';' is required.

in B. "Not just... but a variety" seems clumsy or a kind of a run on sentence to me.

OA and explanation plz...

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

Joining two independent sentences, hence ; is needed. Eliminate A,B.
C. recent studies + Has -> SVA issue.
E. in demonstration of is incorrect.

D wins.

Thanks for this explanation, Adam!

I had a doubt.. Since variety is a quantity and for quantities the object of the prep phrase is treated as the subject, (eg: A number of students ARE...) the verb must be "have" since studies is plural. Can you please explain this?

Thanks!!
