Comment on Subject-Verb Agreement - Part II

The proliferation of computer games designed to involve many players at once were first developed before the widespread availability of high-speed internet connections.

what is wrong in this sentence?

The proliferation (of computer games designed to involve many players at once) were first developed before the widespread availability of high-speed internet connections.

The part in the brackets modifies "proliferation." That is, it tells us what kind of proliferation we're talking about. So, the subject is "proliferation." This is a singular subject, and "were" is a plural verb.

Singular noun, plural noun, or singular noun + singular verb ?

Singular noun, plural noun, or plural noun + plural verb ?

Could you please explain? If I use the word "or", does a verb depend on the closest noun?

The rule for neither/nor (starting at 6:25) also applies to or.

The noun that's closest to the verb is the noun that must match the verb (with regard to singular/plural).

So, "Singular noun, plural noun, or singular noun + singular verb" is correct.

Likewise, "Singular noun, plural noun, or plural noun + plural verb" is correct.

Check the list of pronouns at 1:10 of the video, and you'll see that the indefinite pronoun "every" is always singular.

My friend just told me "none of the cars is green" is grammatically correct. Because "none" is the contraction of "no one", hence "none" is singular.

"None" is under on your "Dual-purpose" section of words. Therefore, I would have to look at the noun to decide whether I should choose "is/are". In my friend's sentence, "cars" is plural, so I thought I would have to use "none of the cars ARE green." I think I'm confused.

Yes, I've heard of that strategy as well.

What's important is how the GMAT handles "none," and that's what the video covers.

Brent,

This is very helpful. I am curious, do you have the summary pages of each lesson? It might be handy for a quick review. You can review while in the Subway or the bus

Even if the indefinite pronoun "every" is always singular, doesn't the addition of "and" make it plural?

No, "every" is always singular (even if there's an "and")

Thank you for the clarification, Brent :)

Can you please breakdown singular vs plural verbs? I am struggling how "gets", and "cares" is singular while get and care is plural. I thought typically when you add "S" to a word it makes is plural? English isn't my first language and grasping this concept is confusing.

The construct for VERBS is different from that of NOUNS.

We typically change a NOUN from singular form to plural form by adding an "s"
EXAMPLES:
dog (singular)..... dogs (plural)
apartment (singular)..... apartment (plural)
cloud (singular)..... clouds (plural)

With VERBS, the singular form typically ends with "s"
EXAMPLES:
jumps (singular)..... jump (plural)
smiles (singular)..... smile (plural)
plays (singular)..... play (plural)

Pls explain the solution to the following question:

Noting that the price of oil and other fuel components, a major factor in the cost structure of an airline, have risen and will continue to rise, the company management was pessimistic about their outlook for the upcoming quarter.

a) have risen and will continue to rise, the company management was pessimistic about their
b) have risen and will continue to rise, the company management was pessimistic about the
c) will continue to rise, the company management was pessimistic about the
d) has risen and will continue to rise, the company management was pessimistic about their
e) will continue to rise, the company management was pessimistic about their

Glad to help!

First off, what rose? The PRICE did.

So, if we ignore the fluff, we get: "Noting that the PRICE ... HAVE risen."

No good. We need the singular HAS risen to agree with the singular PRICE

For this reason, we can ELIMINATE A and B (since they both have "HAVE risen")

Next we have an issue with COMPANY MANAGEMENT.

Answer choices D and E both handle the COMPANY MANAGEMENT issue the in the same way.

Both have "...COMPANY MANAGEMENT (singular) WAS (singular) pessimistic about THEIR (plural) outlook..."

There are two issues here. First, we have singular WAS and plural THEIR both attached to the singular subject MANAGEMENT.

Second, it makes now sense that MANAGEMENT is pessimistic about ITS OWN outlook of event. So, MANAGEMENT is pessimistic about its own pessimism?

For these reasons, we can ELIMINATE D and E.

So, the correct answer is C

Cheers,
Brent
