The most favorable locations for the growth of
glaciers, rather than being the cold, dry polar

regions, would be instead the cool, moist middle
latitudes, where there is abundant precipitation
and where it is cold enough to allow some snow
to accumulate year by year.

the cool, moist middle latitudes

The OA is B.Can anyone explain the defect in C...

See the part of sentence after the underlined part.It says '....... where there is abundant precipitation
and where it is cold enough to allow some snow
to accumulate year by year.' It refers to the favorable place(cold,dry regions) where glacier can form.C changes the meaning of the sentence.If we use C,it means that-cool,moist latitudes are favorable but cold,dry regions are unfavorable for glacier formation.This is complete opposite to what the actual meaning of the sentence should be.Hence it is option B
The number of acres destroyed by wildfires, which have become an ongoing threat due to drought and booming population density, have increased dramatically over the past several years, prompting major concern among local politicians.

have become an ongoing threat due to drought and booming population density, have increased
have become an ongoing threat due to drought and booming population density, have been increasing
has become an ongoing threat because of drought and booming population density, has increased
have become an ongoing threat due to drought and booming population density, has increased
have become an ongoing threat because of drought and booming population density, has increased


Experts, i seek ur help to understand the difference between the usage of "due to" and "because of".

Here is a summary of "due to" vs "because of"

  1. Use due to only to modify nouns.
  2. Usage of due to is correct, if the sentence makes sense when due to is replaced with caused by.
  3. Use because of to modify verbs.
  4. Due to & because of are not interchangeable.


I have covered this in detail in our blog at https://e-gmat.com/blogs/?p=137

"Due to" Vs "Because of" in the context of the following question:

The number of acres destroyed by wildfires, which have become an ongoing threat due to drought and booming population density, have increased dramatically over the past several years, prompting major concern among local politicians.

A: have become an ongoing threat due to drought and booming population density, have increased
E: have become an ongoing threat because of drought and booming population density, has increased

Meaning:
The original sentence states that the number of acres that are destroyed by wildfires has increased over the past several years.
The sentence also describe the wildfires. These wildfires have become on ongoing threat because of two reasons - drought and booming population density. Note carefully that drought and booming population density are the two reasons for why the wildfires have become an ongoing threat.

Due to Vs Because of.
Now we know that "due to" can only be used to modify nouns. But in this original sentence, "due to" is used to present reasons for the verb - "have become". Thus, this usage is incorrect. "Because of" should be used here since it is used to describe the verbs. Additionally, you can apply the check - caused by - here. If you replace "due to" with "caused by", the sentence will not make sense since it will then describe "ongoing threat" and not "why wildfires have become ongoing threat".

I would suggest you note down its usage. You can read more at this link: Sequence of Verb Tenses

Thank you Payal for the link. This is definitely helpful!!!

I have understood the logic in sequence of verbs. There is one more thing I want to clarify:
In the link above there is no example of "simple present verb" + "Simple Past Infinitive" (as in "appear to be equipped"). Is it because it is generally wrong english? If not then how and when this combination is used

Note here that appear to be equipped is incorrect because it would imply that to the author these Neanderthals still appear to be equipped. This is not correct since the author in the present context of time has already noted a contrast through the use of the word but. Refer back to the intended meaning discussion above.


You are trying to say that that "appear to be equipped" is wrong because it implies that the Neanderthals are still existing (which is untrue)

And finally how do you rate this problem (easy/medium/hard) for a 700+ score
(I am assuming you are an expert in English by the quality of your reply)

Hi Everyone,
Please help me out over the subject-verb agreement in the following:

'A majority of railway commuters reads or listens to music while travelling.'

According to Manhattan SC, it is correct. But I think plural verb should have been used here. Please give your comments.

Thanks,

Here the difference between not..but and rather than is used.... you should be clear with the fact that not ..but is used to compare the likely equivalent ...whereas rather than is used to compare the unlikely equivalent..so the answer has to be B.
You are correct.

what about...Majority Wins!!!??

what about...Majority Wins!!!??

Hi...Quantity words such as "majority","minority" and "plurality" are either singular or plural,depending on their context.
If you want to indicate the many individual parts of the totality,usea plural verb.
If you want to indicate the totality itself,then use a singular verb form.
Example: The majority of the students in this class are hard workers.
The noun following the "of" will indicate whether the verb is singular or plural.
In the above example, the noun "students" that comes after "of" is in plural form and hence "are" is used.
Majority of the class is absent today - Here "class" is a singular noun and hence "is" is used.

Very well said sabby87...

Just adding to what sabby87 has already stated:

The majority of people have cast their votes. - PLURAL
Here we are emphasize on individual items of the group = so plural.

In the jury, majority has voted against the defendant. - SINGULAR
Here we emphasize on the total nature of the group = so singular.

That being said, I do not believe this is a frequently tested topic. In OG12, only question 82 uses the word majority and that too in the non-underlined portion of the sentence and that too not as a subject. If we consider CR sentences as any indication of what GMAT considers correct and incorrect, then there are two questions in which majority is used and in both occurrences it is used as plural - Q 109 and 117.

In summary, majority can be either be singular or plural, depending on the context. And these terms are not tested frequently on GMAT.

"appear to be equipped" is correct English usage. Check out the headline of this article at wsj.com Science Journal - WSJ.com

Infact this usage is simply "appear to be X", where X is really an adjective. In this case, equipped is a verb-ed word that acts as an adjective.

It is similar in usage to the "appear to be" in the following sentence:

Tom appears to be calm when he is around his co-workers.

Note - calm here is an adjective. On similar lines "equipped" is an adjective.

Hope this helps...:)

Yes, you are correct. This is the reason why appear to be equipped is incorrect.

I am not sure exactly sure about what you mean by "rate this problem for a 700+". If you would like to get an idea of where you stand in SC, I recommend that you a diagnostic test for SC. We offer one free on our website or you could take one on grockit. Having said that, I would call this problem a 650 level - medium-hard difficulty level.

And as far your comment about "expert" goes, I am the curriculum designer for e-GMAT SC course. :)

In 'majority wins', majority is taken as single entity. So it is singular. Source- Manhattan SC

1. As a result of medical advances, many people that might at one time have died as children of such infections as diphtheria, pneumonia, or rheumatic fever now live well into old age.

This sentence states a comparison. It states that as a result of medical advances many people now live well into old age. These people in the past would have died in their childhood.

Choice D has parallelism error since it does not maintain the order of words to maintain parallelism.

The correct order in this sentence is established using the non-underlined portion of the sentence -
People - timing of verb - verb - age group of people. Per this choice, the order of words of element 1 is People - age group of people timing of verb - verb.

Boss can you plx throw some more light on parallesim concept...i always get confused..with example please.

I believe you are having trouble identifying parallelism in this sentence because there are no evident markers such as like, either..or, and, but, etc. In this sentence, on the other hand, you need to understand the meaning of the sentence to establish that there is parallelism.

Lets take a simpler sentence:

Many people who once purchased laptops now purchase tablets.

What does this sentence mean?
It talks about the change in buying behaviour of people over the course of time. In past people bought laptops. In present they purchase tablets. So the sentence is comparing the buying behavior of people in the past with the buying behavior of people in the present. And hence this comparison should be expressed using a parallel list.

Understanding what the sentence intends to communicate is the single most important step that many people skip. So before you even start to worry about the errors in a sentence, try to get the sense of what the sentence is trying to state. As you understand that, the picture of modifiers, parallelism etc. will become more clear in your mind and will ultimately come to your aid in your error analysis.

Let me know if you have any other questions pertaining to this.
