A Dartmouth-led research team has discovered that unlike the males of most species of crickets, a certain group of male crickets call female crickets to them by the use of high frequency sounds, but not low frequency ones, and they use high frequency sounds similar to that of a predator such as a bat.

Official Solution:

A Dartmouth-led research team has discovered that unlike the males of most species of crickets, a certain group of male crickets call female crickets to them by the use of high frequency sounds, but not low frequency ones, and they use high frequency sounds similar to that of a predator such as a bat.

A. a certain group of male crickets call female crickets to them by the use of high frequency sounds, but not low frequency ones, and they use high
B. a certain group of male crickets call female crickets to them by the use of high frequency sounds, rather than using low frequency ones, and use high
C. the males of a certain group of crickets call female crickets to them using high frequency sounds, rather than low frequency ones, high
D. the males of a certain group of crickets call female crickets to them by using high frequency sounds, but not low frequency ones, they use high
E. the males of a certain group of crickets call female crickets to them using high frequency sounds, rather than low frequency ones, and using high


A. the males of most species of crickets is wrongly compared with certain groups of male crickets. males is not parallel to groups. by the use of is unnecessarily wordy. The use of but not does not clearly convey that most other male crickets use low frequency sounds. Insertion of they is not required.

B. the males of most species of crickets is wrongly compared with certain groups of male crickets. males is not parallel to groups. Violates parallelism with by the use of... instead of using.

C. Correct. Eliminates the above errors. Introduces an absolute phrase correctly to describe high frequency sounds further.

D. The use of but not does not clearly convey that most other male crickets use low frequency sounds. They use high frequency…. is a run-on sentence.

E. Using high frequency sounds…as a bat is a sentence fragment.


Answer: C

This is a very weird question. Anyway aren't we supposed to have :
A Dartmouth-led research team has discovered that unlike the males of most species of crickets, a certain groups of male crickets call female crickets to them by the use of high frequency sounds, but not low frequency ones, and they use high frequency sounds similar to (THOSE OF predators such as) or (TO THE HIGH FREQUENCY SOUND OF) a predator such as a bat.

Another issue with question: In the correct answer
"... the males of a certain groups of crickets ...." how is 'a certain groups' correct?
Shouldn't it be 'males of certain groups of crickets'?

There are actually number agreement issues in every single choice. It made my head spin. I ended up guessing out of frustration and the desire to move on.

I'm starting to doubt the verbal questions in this database. In the OG and other sources I nail SC but a lot of these questions seem odd. My scores are also 42-44 in official practice tests but nothing over 40 on these CATs :(

Your first point is valid - there is a number disagreement (a certain groups). We are correcting the question - thank you for pointing out.

sayantanc2k : Please clarify my doubts. The last part of the sentence "high frequency sounds similar to that of a predator such as a bat" sounds very odd and confusing.
What does it modify? I think a preposition is required for it to make sense. Some conjunction to specify how the phrase is connected to the sentence. I think "as" would make sense.

The last part of the sentence is an absolute phrase modifier. An absolute phrase modifier modifies (provides some more information about) the entire main clause in some way. The structure of an absolute phrase is as follows:
Noun / Noun phrase + Noun modifier

Here,
Noun phrase = high frequency sounds
Noun modifier = similar to that of a predator such as a bat

Following is another example of absolute phrase modifier (from Manhattan SC guide):
Scientists have found high levels of iridium in certain geological formations around the world, results that suggest the cataclysmic impact of a meteor millions of years ago.

sayantanc2k I dont think 'high frequency ...' is an absolute modifier. Absolute modifier modifies the entire clause. This one, however, modifies only high frequency sounds. The example which you provided is the perfect example of an absolute modifier which modifies results. The main clause in the question stem states that "male crickets call the female crickets". An absolute modifier should modify the 'how they call' part, isn't it?

A modifier cannot modify itself - the part "high frequency sounds similar to that of a predator such as a bat" cannot modify "high frequency sounds". You have erroneously considered only "similar to that of a predator such as a bat" the absolute modifier, but the complete "high frequency sounds similar to that of a predator such as a bat" is the absolute modifier.

The absolute modifier modifies the clause in some way. (what kind of sound is used to call the female crickets?)

I think this is a high-quality question and the explanation isn't clear enough, please elaborate. Can you please explain how D is a sentence fragment and E is run on sentence.

You seem to have reversed the errors.

D is a run-on: Two clauses are joined by a comma (without a conjunction):
Clause 1: The males call
Clause 2: they use

E has a fragment at the end: The modifier "using high frequency sounds similar to that of a predator such as a bat" does not have an antecedent or a clause to refer to.
