Hello Everyone!

(C) to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and

This option is INCORRECT because the comma after "region" creates an awkward comma splice. It also doesn't work to say that high pressure is "building, and bring fair and dry weather..." because it's not parallel. It should be "building and bringing" for it to be parallel! It also says that ALL of the actions happen at the same time, which isn't accurate. First, the cool air mass comes in and builds pressure, and THEN fair and dry weather happens over the next several days.

Hi, I have a question. You said "bring" and "building" are not parallel but I think "bring" can be parallel to "usher". The parallelism is just fine. For example: I entered the classroom at the last minutes, fellow students looking, and found my seat quickly. Can you say this sentence is wrong because "found" and "looking" are not parallel?

Or the standard for eliminating choice c is because the sentence has an adverbial modifier between two verbs and that makes the meaning ambiguous just as two V-ing noun modifier can't be put in between two nouns?

GMATNinja Do you think the parallelism in choice C is ok here? What standard should I based on when I am stuck between C and E?

GMATNinja Thanks for your amazing explanations.

Can you please elaborate on why the use of "which" isn't wrong on option E? How can we generalize this touch-rule exception?

Another example would be that question: https://gmatclub.com/forum/the-use-of-l ... 83581.html

Thanks!

Gusty westerly winds will continue to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will bring fair and dry weather for several days.

Gusty westerly winds will continue to usher in a seasonably cool air mass into the region, as a broad area of high pressure will build and bring fair and dry weather for several days.


(A) to usher in a seasonably cool air mass into the region, as a broad area of high pressure will build and

(B) ushering in a seasonably cool air mass into the region and a broad area of high pressure will build that

(C) to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and

(D) ushering a seasonably cool air mass in the region, with a broad area of high pressure building and

(E) to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will


Comma + which : LINK 1 & LINK 2 & LINK 3

intended meaning:
The winds will continue to do X and Y simultaneously.......... and the result will bring dry weather.......


WILL is incorrect because it incorrectly implies that X and Y do not happen simultaneously.... but incorrectly implies that Y happens after X


I was initially skeptical about option E because "which" was touching a verb.... but the verb in this sentence acts as a descriptive verb (meaning it describes the nature of the preceding noun rather an action performed by the preceding noun)
Therefore the descriptive verb acts almost as a noun modifier? so that the which can jump over and modify the preceding noun.

Q.Gusty westerly winds will continue to usher in a seasonably cool air mass into the region, as a broad area of high pressure will build and bring fair and dry weather for several days.
Option-C: to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and
Can anyone tell me why is the parallelism wrong here I dont see no problem with parallelism for me Gusty winds will continue to usher and bring fair and dry... The structure the way I see is that broad area of high pressure is not a part of list and just a modifier modifying region and since there is no other place for it to be placed its okay being placed between a list

Hello Everyone!

There seems to be a lot of great discussion on this question already, mostly around how to answer this type of question quickly. Let's take a fresh look at it, and figure out how to tackle such a difficult question in a timely manner!

To get started, here is the original question, with any major differences between each option highlighted in orange:

Gusty westerly winds will continue to usher in a seasonably cool air mass into the region, as a broad area of high pressure will build and bring fair and dry weather for several days.

(A) to usher in a seasonably cool air mass into the region, as a broad area of high pressure will build and
(B) ushering in a seasonably cool air mass into the region and a broad area of high pressure will build that
(C) to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and
(D) ushering a seasonably cool air mass in the region, with a broad area of high pressure building and
(E) to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will

After a quick glance over each option, there are a few major differences we can address that will help narrow our options down quickly:

1. to usher / ushering
2. into / to / in
3. conjunctions & punctuation after "region"
4. each option's ending

Let's look at #1 on this list first: to usher / ushering. This was a tough one for a lot of people, and for good reason! As it turns out, you can use both of these in this sentence and they'll work. If you find yourself stuck on to usher / ushering for too long, it's a good sign that you need to move on to something else on the list. You can always come back to it later if you need to!

Instead of staying stuck on #1 for too long, let's jump into #2 on the list: into / to / in. One thing that jumped out to me right away is that some options say "ushering/to usher in....into the region," which is redundant! You can usher something into a region, or usher in something to a region, but you cannot usher in something into a region! Let's see which options we can eliminate that are redundant:

(A) to usher in a seasonably cool air mass into the region, as a broad area of high pressure will build and
(B) ushering in a seasonably cool air mass into the region and a broad area of high pressure will build that
(C) to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and
(D) ushering a seasonably cool air mass in the region, with a broad area of high pressure building and
(E) to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will

You can eliminate options A & B quickly because they are redundant.

This leaves us with only 3 options left, so let's focus on #3 and #4 on the list: conjunctions/punctuation after "region" & their endings. We need to make sure commas and conjunctions are being used correctly, and that the endings work with the rest of the sentence. Here's how each option breaks down:

(C) to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and

This option is INCORRECT because the comma after "region" creates an awkward comma splice. It also doesn't work to say that high pressure is "building, and bring fair and dry weather..." because it's not parallel. It should be "building and bringing" for it to be parallel! It also says that ALL of the actions happen at the same time, which isn't accurate. First, the cool air mass comes in and builds pressure, and THEN fair and dry weather happens over the next several days.

(D) ushering a seasonably cool air mass in the region, with a broad area of high pressure building and

This option is INCORRECT because it uses the phrase "building and bring," which isn't parallel. We don't really have a problem using the comma before "with" in this case because it's being used to indicate that everything after it is non-essential information (which it is). The meaning of the sentence doesn't change if you take it out, so it's a non-essential phrase that merely adds colorful details. This sentence also suggests that ALL of the actions happen at the same time, instead of in a particular order.

(E) to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will

This option is CORRECT because it's not redundant (to usher...into the region), "while" is being used correctly to show two actions occur at the same time, and the conjunction "which will" properly shows that the action "bring fair and dry weather for several days" happens after the cool air mass shows up. This sentence is clear, concise, and shows the proper order of events!

There you go - option E is the correct answer, and hopefully we got to it quickly enough for you to tackle more GMAT questions in the allotted time!
