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.

Yes!

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
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

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

A--> which is modifying humans.
error not only because which cannot modify humans but also because meaning is nonsensical.
above humans the sensitivity begins to differ.

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

SVA issue

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

which humans what kind of humans?
the ones over a range of frequencies from 100 to 5,000 hertz

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

same as C
Further, the statement is true only when the comparison is made.

Do let me know if you want further explanation.

Purpose of prep phrase in a sentence

prepositional phrases can serve the purpose of adverb or of adjective.
over a range of frequencies is a prepositional phrase.
infact it is a prep phrase and within that prep phrase we have another prep phrase
over a range--> prep phrase modifying humans (noun )
of frquencies--> prep phrase modifying range( noun )

Construction of prep phrases
first word is preposition
ends with noun/ noun equivalent. Noun can have further modifiers attached to it.
( no verb though, therefore it is a phrase. phrases lack verb. Clauses have verb. )

Now have a look at SC under discussion
humans over a range of frequencies

humans--> noun
over a range--> prep phrase

as over a range is prep phrase
and as prep phrase can serve the purpose of adj or adv, its position/ placement in a sentence determines whether it is serving the funtion of adj or adv.

humans over a range of frequencies
what is the position of over a range of frequencies?
it is placed adjacent to noun (humans)

Therefore it serves the function of adjective ( adjectives modify noun and are placed next to nouns that they modify)

The question is can over a range of frequencies, a prep phrase, modify noun (humans)?
SURE! because it is a prep phrase.
prep phrase can modify noun.
But the problem is, in doing so, the meaning becomes nonsensical.
In GMAT SC, not only grammar but also meaning is a thing.
Grammar should be correct.
Meaning should also be sensical.

Here Grammar is correct.
Meaning is nonsensical.

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

sensitivity is similar
subject verb adjective ( is is a linking verb )

linking verb (is ) connects subject( sensitivity ) with adjective (similar)

How can you modify adjectives?
with adverbs.

sensitivity is remarkably similar.
How similar?
remarkably similar.

Can you modify adjectives only with adverbs?
No. We can also modify adjectives with constuctions that can function as adverbs(i.e in the same way adverbs function in a sentence)

sensitivity is remarkably similar over a range of frequencies from 100 to 5,000 hertz
How similar?
remarkably.

when?/ where is sensitivity similar?
over a range of frequencies from 100 to 5,000 hertz

which frequencies?
ones from 100 to 5,000 hertz .
As it has answered which, it is adjectivial modifying frequencies (noun)

adjectives answer
which?
what kind of (qualitatively)
and
how much?
how many? (quantitatively)
( there are quantitative adj and qualitative adjectives )

adverbs answer
where?
when? ( therefore time modifiers are adverbial. However, time/date/day when clause or time/day/date, when clause is a different case. In that case what follows time is actualy describing time/ giving more info about time)
how?
how often?
how long?
how likely?
why?
to what extent?
to what degree?

Direct Objects answer
whom?
What? ( irrelevent to this SC but relevent to GMAT )

If want further explanation, dont hesitate at all. Never!

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
