Quote:
A. Over a range of frequencies from 100 to 5,000 hertz, monkeys and marmosets have a hearing sensitivity remarkably similar to humans

(A) sounds pretty good! But it’s wrong, anyway.

For starters, the comparison is off: the phrase “monkeys and marmosets have a hearing sensitivity remarkably similar to humans…” literally compares “hearing sensitivity” to humans themselves. And that doesn’t make sense: we’d need to compare the hearing sensitivities of the various creatures.

Plus, the non-underlined portion, “above which the sensitivity begins to differ” should modify the “range of frequencies from 100 to 5,000 hertz.” Ideally, those two phrases should be next to each other, and they aren’t in (A).

So (A) is gone.

Quote:
B. Compared to humans, the hearing sensitivity of monkeys and marmosets are remarkably similar over a range of frequencies from 100 to 5,000 hertz

(B) has lots of tasty problems. The comparison is still wrong: “humans” themselves are being compared to “the hearing sensitivity” of monkeys and marmosets.

There’s also a nice subject-verb error: “the hearing sensitivity… ARE remarkably similar…” Nope, that’s bad.

We can eliminate (B), too.

Quote:
C. Compared to humans over a range of frequencies from 100 to 5,000 hertz, the hearing sensitivity of monkeys and marmosets is remarkably similar

We still have a clean comparison error here: “compared to humans… the hearing sensitivity of monkeys and marmosets…” Nope, that still compares humans themselves to the hearing sensitivity of these other creatures. Not cool.

(C) is out.

Quote:
D. The hearing sensitivity of monkeys and marmosets, when compared to humans over a range of frequencies from 100 to 5,000 hertz, is remarkably similar

Once again, it doesn’t really make sense to compare “the hearing sensitivity” to humans themselves. Basically, (D) repeats the same mistake as the previous three answer choices.

Plus, I don’t really like the use of “when” in this situation: “when compared to” suggests that the hearing sensitivities are similar only in the exact moment when they’re being compared to each other – and that really doesn’t make sense. That’s subtle, but there are a few other official GMAT questions that misuse the word “when,” so I figure that the issue deserves a quick mention.

Finally, the modifier in the non-underlined portion (“above which the sensitivity begins to differ”) should ideally be placed right next to “the range of frequencies from 100 to 5,000 hertz”. And that’s not happening in (D).

So we have lots of reasons to eliminate (D).

Quote:
E. The hearing sensitivity of monkeys, marmosets, and humans is remarkably similar over a range of frequencies from 100 to 5,000 hertz

This looks fine. The comparison is now clear at the beginning of the sentence: humans, monkeys, and marmosets all have similar hearing sensitivities. The non-underlined modifier (“above which the sensitivity begins to differ”) is right next to the thing it modifies (“a range of frequencies from 100 to 5,000 hertz”).

So (E) is our answer.

Over a range of frequencies from 100 to 5,000 hertz, monkeys and marmosets have a hearing sensitivity remarkably similar to humans, above which the sensitivity begins to differ.

A. Over a range of frequencies from 100 to 5,000 hertz, monkeys and marmosets have a hearing sensitivity remarkably similar to humans
non underlined portion talks about frequencies- so noun modifier issue and comparing hearing sensitivity of monkeys to humans. Illogical.
B. Compared to humans, the hearing sensitivity of monkeys and marmosets are remarkably similar over a range of frequencies from 100 to 5,000 hertz
Comparing humans to hearing sensitivity of monkeys and marmosets, non sensical.
C. Compared to humans over a range of frequencies from 100 to 5,000 hertz, the hearing sensitivity of monkeys and marmosets is remarkably similar
Comparing humans to hearing sensitivity of monkeys and marmosets, non sensical.
D. The hearing sensitivity of monkeys and marmosets, when compared to humans over a range of frequencies from 100 to 5,000 hertz, is remarkably similar
When Compared to is not idiomatic.
E. The hearing sensitivity of monkeys, marmosets, and humans is remarkably similar over a range of frequencies from 100 to 5,000 hertz

My answer is E.
I chose E because the other options (options A-D) inappropriately draws a comparison between ‘the hearing sensitivity of monkeys and marmosets’ and ‘humans’.
Option E draws a comparison between ‘the hearing sensitivity of monkeys and mamosets’ and ‘the hearing sensitivity of humans’

A - hearing sensitivity of monkeys and marmosets is compared to humans instead of humans'.
B, C, D- same issue as A
E - incorrect comparison eliminated.
Uses the correct form: hearing sensitivity of X, Y and Z.
The non underlined part starting from above which correctly modifies 5000 Hz.

Over a range of frequencies from 100 to 5,000 hertz, monkeys and marmosets have a hearing sensitivity remarkably similar to humans, above which the sensitivity begins to differ.[/quote]

We need a numerical value before " comma + above. So A, C, and D are out. In B, S-V error.

Hence (E)

A. Over a range of frequencies from 100 to 5,000 hertz, monkeys and marmosets have a hearing sensitivity remarkably similar to humans

B. Compared to humans, the hearing sensitivity of monkeys and marmosets are remarkably similar over a range of frequencies from 100 to 5,000 hertz

C. Compared to humans over a range of frequencies from 100 to 5,000 hertz, the hearing sensitivity of monkeys and marmosets is remarkably similar

D. The hearing sensitivity of monkeys and marmosets, when compared to humans over a range of frequencies from 100 to 5,000 hertz, is remarkably similar

E. The hearing sensitivity of monkeys, marmosets, and humans is remarkably similar over a range of frequencies from 100 to 5,000 hertz

(E)

+1 for option E.

The question hinges on comparison. Logically the only comparison possible is - hearing sensitivities of humans , monkeys , and marmosets. Only option E fits the bill.

A,B,C,D ... all the options have comparision error. Hearing sensitivity of monkeys is compared to humans.. This is wrong.

Hence E is our option

GMATNinja, I don't understand this. It seems that 'when' is being used to mean 'in what circumstances'; that circumstance being compared to human hearing sensitivity within that defined range. Using different ranges, say 6000-7000, may not be comparable. Do you have other examples handy to explain misuse?

Hi, Isn't there a subtle meaning change in option E? It seems that the comparison is between the hearing sensitivity of monkeys and marmosets with that of humans. But as E is worded, it seems to compare the hearing sensitivity of the 3 -> monkeys vs. marmosets vs. humans. For example, we could infer the meaning that above 5kHz, the hearing sensitivity of monkeys and marmosets starts to differ, whereas it seems to me thats not what the original intent (Monkeys/Marmosets hearing vs. Hearing of humans) was.

I concur with what you said, option E indeed implies that above 5,000 Hz the hearing sensitivity of monkeys, marmosets and humans starts to differ. GMAT doesn't ask you to preserve the original meaning, so you can play around with the original meaning as long as it conveys a logical and grammatically correct idea.
There are some glaring errors in other options:
1) "above which the sensitivity begins to differ" - seems to modify humans - INCORRECT
2) Humans compared to hearing sensitivity of monkeys and marmosets - INCORRECT
3) Humans compared to hearing sensitivity of monkeys and marmosets - INCORRECT
4) Humans compared to hearing sensitivity of monkeys and marmosets - INCORRECT
5) This correctly compares the hearing sensitivities of monkeys, marmosets and humans and as you pointed out this sentence conveys the idea that above 5,000 hz the hearing sensitivities of all the 3 starts to differ - CORRECT

The hearing sensitivity
of
monkeys,
marmosets,
and humans
is remarkably similar over a range of frequencies from 100 to 5,000 hertz

Non underline part contains text "above which ... Differ"

Means just before that we need something so that it makes perfect sense with it

B and E does exactly that

B is incorrect as humans are compared with hearing capacity of monkeys so E is correct

The hearing sensitivity of monkeys, marmosets, and humans is remarkably similar over a range of frequencies from 100 to 5,000 hertz....

Could anyone please explain the use of singular verb 'is',in this correct answer choice, for referring to sensitivity of three animals?

The subject here is "hearing sensitivity" - singular, hence singular verb "is".

Why 'hearing sensitivity' of three animals is singular? Why isn't it used in plural form i.e. sensitivities??

words in prepositional phrases do not serve as subjects, except when quantity is expressed.
ex. The box of nails is on the table. The pack of cards is on the floor... subjects are box and pack.

Exception : When expressing quantity,
ex. Some of the stones, which were thrown by Sam in Thames, were round in shape.
