Hey GMATNinja,

I was stuck with options D&E. But chose D since E was nonsensical.
But I found it really hard to eliminate D because "it" was not referring back to a noun but to a phrase " the number of chirps per minute ".
Is this usage grammatically correct ??

Interesting question, right? All sorts of funky stuff going on here with meaning and pronouns.

For those of you who missed it, we went through this question in our live YouTube session this past Monday. The video is available here.

Quote:
A. for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve.

The nice thing about (A) is that the subject-verb agreement is clearly wrong. "The number of chirps per minute... rise and fall." No reason to overthink this one. (A) is gone.

Quote:
B. for attracting females rises and falls in accordance with the surrounding temperature, which can in fact serve

Subject-verb agreement looks fine here, but "which" seems to modify temperature, and that doesn't make sense. The temperature can serve as a thermometer? That's messed up. Eliminate (B).

Quote:
C. in attracting females rise and fall in accordance with the surrounding temperature, in fact possibly serving.

Same subject-verb error as in (A), so (C) is gone, too.

Quote:
D. to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve.

Heh heh, here's where it gets interesting.

Let's talk about the pronoun "it". On the face of things, it looks like "it" could refer back to temperature (the nearest singular noun), and that's illogical. If we reach further back, "it" could refer to "male", "minute", "number", or "cricket." So it's ambiguous, right?

Nope! Notice that "it" is the subject of a dependent clause -- the second clause in the sentence. What's the subject of the first (independent) clause? "The number", or "the number of chirps per minute." And the GMAT is weirdly consistent about this: if a sentence contains two clauses (either one dependent and one independent, or two independent clauses) and the second clause starts with a pronoun, then the pronoun can refer unambiguously to the subject of the first clause.

So "it" refers to "the number of chirps per minute", without any trouble at all. Let's keep (D).

Quote:
E. to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving.

Hm, nothing looks wrong here grammatically. If I'm being honest, I'd keep (E), too.

Now let's compare those last two:

D. to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve.
E. to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving.

These two are identical, other than the last little bit of the underlined portion. And there's a subtle little meaning difference between these two. (D) is saying that the "number of chirps per minute" CAN serve as a thermometer if you wanted it to. (E) is saying that the number of chirps "in fact" (="definitely") "possibly" (≠"definitely) serves as a thermometer. And that's nonsense: how can something "in fact" and "possibly" serve as a thermometer?

That's subtle, but enough to make (D) the right answer.

The grammar in an OA is always correct! And this usage is quite common. Consider a silly example: "The number of dogs my toddler has frightened with her aggressive displays of affection is high, and if it continues to increase, we will likely receive a reprimand from the neighborhood association." Here "it" refers to "the number of dogs" or "the number." If that number "continues to increase" there will be consequences. Perfectly logical.

I hope that helps!

Hey GMATNinja

Isn't the conjunction "and" used only in case of joining two independent clauses? Is the 2nd clause dependent or independent?

Hi Gmatninja ,

Option D also has "and it can in fact serve....."

"Can" denotes possibility...
"in fact" denotes certainty...

So with that subtle logic , option D also does not look correct...

for doing/ to do is not simple.
for doing can be used to show a purpose. consider

the millionaire contribute his money to the state for learning of English.
inhere, learning dose not refer to millionaire . this means the millionaire dose not perform future action of "learning".

our pattern is more simple.
the male used the chips to attract the female
the chips is used by the male to attract the female

so, in the pattern " is do-ed by someone to do", someone will perform action of to do". in our example, "the male" perform the action of "attract".

so, remember " do-ed by someone to do" is not simple.

above text is the reason for which "to attact", not "for attracting" is used.

"My cat definitely CAN jump over the fence." - It is a fact that my cat has the ability to jump over the fence. Does that mean that my cat WILL jump over the fence? Who know? He's pretty lazy, and developed that trait by following my example. (I don't actually have a cat, but if I did, this would be a true story.)

So you can be certain that something is a possibility without being certain that it will actually happen.

I hope that helps a bit!

Cricket Thermometers

Q. Do crickets chirp more slowly as the temperature drops in the fall?

A. In some species of cricket, the number of chirps per minute used by the male to attract females rises and falls along with the outside temperature, and can in fact be used as a rough thermometer.

Easily identified errors:

1- Subject: Number of minutes.. so verb needs to be rises and falls
2- to attract is far better than for attracting

1 eliminates A and C
2 eliminates B

This leaves us with D&E

Between D & E, E is using -ing modifier in wrong sense. temperature measurement is a side benefit not the main point of the preceding clause. Furthermore, It correctly refers to the subject of the sentence in choice D.

IMO D is the correct answer

Isn't ''used for'' wrong in A,B,C? I found that this is wrong in a file, perhaps compiled by carcass , containing 100 hard SC ques from OG and Manhattan.

Hello rma26,

As such the phrase used for is not incorrect.

However, in this official sentence, we need the phrase to attract to show why male crickets use their chirps in a certain manner. Hence use of for attracting is not correct.

Hope this helps.
Thanks.

Hi egmat

Can you pls elaborate a bit more on how the phrase "for attracting" and "to attract" alter the meaning of sentence

I've read a post by egmat on GMAT club in which it is explained that when reason/ intent for something is explicit use "to +verb" and when the context of the sentence requires the "what for aspect" then use "For +verb-ing"
And on reading this question I felt that for + verb-ing would be revealing the reason which is not explicit, but selected D as it was better in its pronoun usage

It boils down to D and E.

In E ,the meaning comes out as the number of chirps is already serving as an approximate thermometer.

However the actual meaning is that the number of chirps can be served as an approximate thermometer.

Therefore E is wrong.

Hi,
I have one doubt regarding the cricket question. Is there a parallelism problem in option E between 'attract' a verb and 'serving' a gerund?
