D: boys’ stress patterns do

This means that the stress patterns of girls more likely leading to depression than stress patterns of boys do(leading to depression)..

But please help me why A is recommended to D? For the sake of parallelism?

Hello! Let’s complete the intended sentence:

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than the patterns of stress that boys experience are likely to result in.

A says:

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than those (patterns of stress) that boys experience are likely to result in.

With D, the sentence would be:

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than boys’ stress patterns do.

So, if you compare this with the intended sentence, at the very least, do is trying to substitute for are likely to result in. Notice that are is an auxiliary verb.

I am pretty sure (unless someone can cite an example to the contrary) that do (and similarly did/does ) cannot substitute for auxiliary verbs. do/did/does can only substitute for main verbs. So, following would be correct:

He runs faster than his classmates do.
- do correctly substitutes for main verb runs

Following would be incorrect:

Jack is more successful than his brothers do.
- do cannot substitute for auxiliary verb is

The correct sentence would be:

Jack is more successful than his brothers are.

If you see any example that violates this, let’s discuss.

Request you to not to post answers/queries/views in question window. This prevents

Hello again mikemcgarry,
I picked A. I could eliminate B, C and D.
I picked A, as i saw it has followed the same structure, but it seems to me that E has the same meaning. I know I am wrong, just can't find out how....

Respect....

Dear nahid78,

I'm happy to respond.

Choice (E) does have the same meaning as (A), but choice (E) is redundant and awkward, whereas (A) is elegant. Choice (A) wins easily---a much better answer.

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than are those that boys experience.

We are looking for an option that properly compare stress that girls experience vs. stress that boys experience

A are those that boys experience ==> Correct - Stress of boys is correctly compared with Girls
B what boys experience ==> Patterns are being compared to stress
C boys’ experience would color=#ed1c24]==> Patterns are being compared to stress[/color]
D boys’ stress patterns do ==> do cannot be the appropriate linking verb
E stress patterns of boys ==> missing verb form

Hence, Answer is A

Hi Experts,
Any reason of choosing A over E? It seems those and that are unnecessary here.

E as such has no error .
but i think A has verb that expresses causality of stress much better than E.

I'm happy to respond.

My friend, did you read my post on the thread from February 14, 2017? I addressed this very question. As a general rule, it's very good practice to read through the entire post before asking a question that has already been discussed. Does this make sense?

Mike

Hi mikemcgarry
As a matter of fact, I did go through your explanations but still
find that those and that are un-necessary in option A.
In fact we have contrasting views since I find E to be more precise.
Let me know gaps in my understanding.
WR,
Arpit

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than are those that boys experience.
A are those that boys experience - Correct
B what boys experience - illogical comparison - comparison of patterns of stress with boys experience
C boys’ experience would - illogical comparison - comparison of patterns of stress with boys' experience
D boys’ stress patterns do - usage of do
E stress patterns of boys - awkward

The sentence is making a comparison, so we have to make sure the comparison makes logical sense and is parallel.

Part of the comparison is girls' stress patterns, so I need to mention stress patterns of boys. B and C are out. (A uses the pronoun "those" to refer to stress patterns, so it stays in.)

Also, I'm specifically comparing how likely the two different patterns are to result in depression- it's not just a straight comparison between different patterns, but the effects of the different patterns - so the comparison needs to indicate this too. This is likely going to be accomplished via a verb, so E is out.

That leaves me with A and D. A uses the same verb in the same tense ("are") while D introduces a new verb ("do"). A also follows a similar format for the rest: "patterns of stress that girls experience" and "those that boys experience." D doesn't. A is more parallel, so that's what I would choose.

WR,

I'm happy to respond.

My friend, this is a subtle matter. I don't know whether English is your first language, but this choice between (A) & (E) certainly could be perplexing to a non-native speaker. Here's everything after the word "that" in choice (A)
(A) . . . the patterns of stress that girls experience are more likely to result in depression than are those that boys experience.
The word "those" is necessary: it's a demonstrative pronoun standing in for "the patterns of stress." The word "that" is not only necessary as a relative pronoun beginning a noun-modifying clause, but it also anchors the parallelism by reflecting the previous "that" (before the word "girls"). This presents us with perfectly parallel endings with the matching noun-modifying clauses "that girls experience . . . that boys experience." This is elegant and well-written, and not a single iota of it is unnecessary.

By contrast, here's (E):
(E) . . . the patterns of stress that girls experience are more likely to result in depression than stress patterns of boys
To the ears of native English speakers, this is a major train wreck. Notice that the definite article "the" is missing, which adds to the awkwardness. Note that, in contrast to (A), there is not even the vaguest attempt to construct a mirrored pattern of matching. This sounds stunted and unnatural. I can see that someone whose first language is not English might be tempted to mistake this construction for concision. The GMAT SC is so challenging, because these writers excel at creating combinations of words that might sound plausible if you don't know the language well but which simply sound off if you are a native speaker. There is often something suspect about putting two nouns together ("stress" + "patterns"), especially if these two nouns were not put together in this way in the first branch of the parallelism. The phrase "the patterns of stress that girls experience" sounds academic and formal, and the phrase "the stress patterns of boys" sounds casual, perhaps as one might see in advertising; this juxtaposition, in corresponding branches of the parallelism, creates a kind of mismatch in level of formality. Add to this that (E) completely omits the definite modifier: that absence makes (E) clankingly awkward. There is absolutely no way (E) could be correct.

My friend, does all this make sense?
Mike

Hi mikemcgarry

Indeed, I am a non-native and that's why had trouble comprehending (E)
The sentence correctly tests both comparison and parallelism if my below understanding
of sentence structure is correct:

Many teenagers undergo stress, (independent clause 1)
but results of a recent study indicate (independent clause 2 with connector but)
that the patterns of stress (that marks start of dependent clause)
that girls experience are more likely to result in depression than (relative pronoun that correctly modifies patterns of stress)
are those that boys experience. (comparison ends; )
A are those that boys experience
B what boys experience
C boys’ experience would
D boys’ stress patterns do
E stress patterns of boys

One additional input: in (A) the phrase following than is a clause which makes more sense
than noun phrase in (E) from parallelism view. There is no verb in (E)

Thanks for detailed explanation.
WR,
Arpit

A are those that boys experience -Correct. "than are patterns of stress that boys experience" --> correct usage
B what boys experience -Wrong.
C boys’ experience would - Wrong.
D boys’ stress patterns do - instead of "do" are is needed to maintain correct comparison
E stress patterns of boys - "are" is missing, making the comparison unambiguous
