I also went with D but here is the OE for B as the correct answer.

Official Explanation:

(A) Notice that answer choice (B) changes the reason is … because to the reason … that. The structure the reason … because may sound fine, but it’s actually redundant: the reason already indicates that you’re about to hear a causal explanation; because conveys the same idea.
(B) CORRECT. This sentence changes the reason is … because in the initial sentence to the reason … that, removing the redundancy. Both and cools and cooling are correct; this split is a red herring.
(C) Between cannot be used to refer to the scientific community, which has more than two members.
(D) By removing reason, this sentence fixes the redundancy in the original sentence. However, the new construction introduces a modifier error. The modifier by doing so (yawning) must be followed by whoever is doing the yawning. For example, by exercising, Jim stays healthy. Jim is the person exercising. You could not say by exercising, a low heart rate keeps Jim healthy. This illogically implies that the low heart rate is doing the exercising. In answer choice (D), by doing so (yawning), blood flow implies that the blood flow is yawning.
(E) The reason … because is redundant. The reason already indicates that you’re about to hear a causal explanation; because conveys the same idea.

Experts please clarify more on the reasoning given for D as the incorrect answer.
Thanks.

My answer is "D" because I think that "among" is inappropriate here. It should be used when there are more than 2 parties but in this situation it's in "the scientific community".
Can anyone explain what's wrong with D? :(

I really don't think B as the answer. Answer should be D. Differences can only be between 2 people, among more than 2 and within a group or community.

Thus, use of among is clearly wrong in the above context. It should be D.

Let's appreciate that 'the reason .... because' expression is redundant. We must drop A, D, and E. Between B and C, the cooling of the brain is the result of the increase in blow flow. Hence the use of modification is the apt style. B is correct.

daagh for me same reasoning works as you have given above.
Only difference following the same path we both should have reached B, but I think you mistakenly typed option C.

Correct me if I am wrong.

Thank you for responses but I don't see any "the reason...because" in choice "D" at all.
Here's my decision process.

A. among the scientific community, some research suggests that the reason people yawn is because doing so increases blood flow and cools ---> Wrong usage of "Among" and redundant
B. among the scientific community, some research suggests that the reason people yawn is that yawning increases blood flow, cooling ---> Wrong usage of "Among"
C. between the scientific community, some research suggests that the reason people yawn is that yawning increases blood flow and cools ---> Wrong usage of "Between" and failed to show the cause and effect increasing blood flow and cooling down the brain
D. within the scientific community, some research suggests that people yawn because by doing so, blood flow increases, thereby cooling ---> the portion after because looks a little wordy but there is no serious error here so I keep this.
E. in the scientific community, some research suggests that the reason people yawn is because the act of yawning increases blood flow, thereby cooling[/quote] ---> redundant

Does anyone have any other reasons to choose "B" over "D"??

Hi Sir, D doesn't use the said redundant expression. Is there any other reason to eliminate D?

But sir the usage of between in C is erroneous. How do you justify that. I would still stick to D.

Although there is still disagreement among the scientific community, some research suggests that the reason people yawn is because doing so increases blood flow and cools the brain.

A. among the scientific community, some research suggests that the reason people yawn is because doing so increases blood flow and cools
B. among the scientific community, some research suggests that the reason people yawn is that yawning increases blood flow, cooling
C. between the scientific community, some research suggests that the reason people yawn is that yawning increases blood flow and cools
D. within the scientific community, some research suggests that people yawn because by doing so, blood flow increases, thereby cooling
E. in the scientific community, some research suggests that the reason people yawn is because the act of yawning increases blood flow, thereby cooling

Verb-ing modifiers separated modify the preceding clause and depict the result of the preceding clause.
Here the yawning results in cooling , Option D suggests that cooling resulted from people.

Second that
I think C is just a typo mistake.

C can not be the answer

This question has a minor mistake. If "community" is replaced with "communities" then it makes sense.

What is the purpose of putting "blood flow increases" in between commas in option D?
I think that makes it modifier and if it is dropped, the sentence becomes nonsensical.

D. within the scientific community, some research suggests that people yawn because by doing so, blood flow increases, thereby cooling


True. D does not contain 'the reason.' Hoverer in D, the modifier, 'thereby cooling' modifies the relative clause ' that people yawn'. This is not correct.

I can agree with B being the answer but only without among. How can we use among for a community. Please clarify this with relevant examples.

Please help. How can B be the correct answer. The scientific community is a single entity and using among with this is incorrect.

Are we going to see such a question on D-Day?

Between is used for two people and among is used for more than two people.
So how come among and between be correct for a singular subject 'the community'?

I have one doubt here how "ämong" is used correctly in answer choice B.
Because it should be among scientific communities not scientific community.

Please explain??
