Comment on Comparisons - Part II

Hi guys, I don't understand how "Sanjay is smarter than any student in his class" implies that he is smarter than himself? Because of "ANY" means that he is smarter than everyone including himself?

If we write "any student," then we are including Sanjay.

For example, let's say that a class consists of Ann, Bea, Cal and Sanjay. If I direct you to choose ANY student in the class, then you could select any student from the set {Ann, Bea, Cal, Sanjay}.

So, if we say that Sanjay is smarter than ANY student in his class, then we are saying that Sanjay is smarter than each member in the set {Ann, Bea, Cal, Sanjay}.

This means that Sanjay is smarter than Ann, Sanjay is smarter than Bea, Sanjay is smarter than Cal, and Sanjay is smarter than Sanjay.

great videos
when to use that and those? referring to 00;50 and 1:12 examples

Use "that" when replacing a singular noun, and use "those" when replacing a plural noun.

At 1:00, can the corrected sentence be "the chemical engineer certification process in Peru is more time- consuming than the process in Brazil"?

That seems reasonable to me. You've included the word "process," so it's clear what we're comparing here.


Please see this question:

Faced with an estimated $2 billion budget gap, the city’s mayor proposed a nearly 17 percent reduction in the amount allocated the previous year to maintain the city’s major cultural institutions and to subsidize hundreds of local arts groups.

Is this sentence correct

I am getting confused between the kind of omitting of words done in parallelism part-III 4:48 where you said that if we encounter any of the answer choices with certain omitted words in a question of parallelism then it is most likely a wrong answer,and the kind of omitting of words with placeholders discussed in this video.

As long as there is no ambiguity, then omitting words is fine (since it results in a sentence that's more concise). That's the most important concept to keep in mind.

Hi Brent,

Can you share link to quiz to practice placeholders, replacement of noun and verb. Also for use of few, less, more, high, etc. Your earlier link for adverb helped me lot, I tried comparison on same link but its simple and placeholders are not tested.

Thanks for your continued support

Here's a quiz for less/fewer (bottom of page): http://www.grammar-quizzes.com/fewerless.html

Much/more (bottom of page): http://www.grammar-quizzes.com/muchmore.html

Still looking for a placeholder quiz!!

Hi Brent,

Love this video! Just one question: Could you give me an example of using "it" as a placeholder in comparison?

Thank you!

Hi Kate,

Here's one: The sky is bluer in Vancouver than IT is in Winnipeg.


Hi Brent,

Please explain why A,B and D are wrong

Question link: https://gmatclub.com/forum/the-number-of-undergraduate-degrees-in-engine...

We can say that X is twice Y, which means X = 2Y
So, if we say that Vancouver's annual rainfall is twice that of Seattle, then we're saying:
Vancouver's rainfall = 2(Seattle's rainfall)

The same goes for "double"
So, if we say that Vancouver's annual rainfall is double that of Seattle, then we're saying:
Vancouver's rainfall = 2(Seattle's rainfall)

When it comes to the word "increase," we typically note the increase with an actual value (e.g., "The temperature increased 5 degrees." OR we note the proportional change (e.g., "The population increased 5 percent"0

Answer choices A and B combine "increase" with "twice" and "two times." This is both redundant and somewhat nonsensical.

Answer choice D says "WAS more than doubled." This suggests that some entity acted to do the doubling. Here's an analogous sentence:

"Joe WAS hit" - this suggests that something or someone hit Joe.

Alternatively, "Joe hit" suggests that it was Joe who performed the action of hitting.

Since there was no THING or PERSON doubled the number of undergraduate degrees, answer choice D is incorrect.


Hi Brent,

I did select right ans choice i.e. A but want to know is there any difference between "they were" and "they did" in ans choice A and C respectively

WERE and DID are both fine here.

A) ...refiners are paying ... more for crude oil than they were (were PAYING) last year.
Here, the word PAYING is implied.

C) ...refiners are paying ... more than they did (PAID).
Here, the word DID serves as a placeholder for PAID.


Hi Brent,

Which of the following reads better,

"Maple trees shed their autumn leaves earlier than Oak trees do."

"Maple trees shed their autumn leaves earlier than Oak trees shed theirs."

"Maple trees shed autumn leaves earlier than Oak trees do"

To me, the latter two sound better than the first. Please help!
gmat-admin's picture

I think the first two are fine, but the third sentence has an ambiguity problem. The ambiguity lies in whether the maple trees shed their own leaves or some other trees' leaves.

Analogous sentence: Abbie brushes hair.
This could be interpreted as Abbie brushing hair other than her own.
