In some species of cricket, the number of chirps per minute used by the male for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve as an approximate thermometer.

A. for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve.
B. for attracting females rises and falls in accordance with the surrounding temperature, which can in fact serve
C. in attracting females rise and fall in accordance with the surrounding temperature, in fact possibly serving.
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.

I will go with D.

C and E are out as they use "serving" instead of "serve" - Don't need continous tense
A is out as it refers to "number of chirps" as "they" - should be singular
Between B and D - I will go with "to attract" instead of "for attracting"

Please advice on OA.

I have a problem with 'D', what does the 'it' in 'D' refer to? Cricket? Chirpts, Number of chirps, temperature? it doesn't have a clear reference.

IMO E

'It' denotes 'the number' of chirps and hence D.

Hi,
'it' refers to the subject 'the number'. 'in fact' in E means 'in actuality' or 'as a matter of fact' something certainty. The usage of 'possibly' after 'in fact' doesn't make sense.

Hence, D

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.
Since the subject in this question 'the number' is singular, the verbs 'to rise' and 'to fall' need to be singular as well. Using this, we can eliminate options A & C.
B can be eliminated due to incorrect placement of a modifier. 'Which....' is incorrectly modifying the temperature instead of the number of chirps.
E can be eliminated due to contradictory contextual meaning through the use of both 'in fact' and 'possibly'.
IMO, Answer is D.

Whats the source???

Op A and Op C has sub-verb agreement error.

used to is correct not used for hence Op B is wrong.

b/w Op E and Op D, i believe both of them make no meaningful sense...as the last part in both of them...in Op D an independent clause and in Op E a modifier....both seems nonsensical...

Still, in worst case i pick, Op D.

Please reveal the source??

IMO D
the number of is singular
Thus singular form of verb.
thus a and c eliminated.

Hi bro,
What is wrong in D??
Independent clauses can be connected by using comma+coordinating conjunction('and'). Is this what you are looking for or did I miss something?

Hi bro,

I have no problem with the structure of the Op D...the structure is okay..the only issue is the meaning of the sentence...may be the meaning is correct but i'm struggling in what actually Op D means in this part only: "it can in fact serve."

Here, i don't understand, if IT is referring to male then "male can in fact serve"...what does this mean here???...i mean this part doesn't seems to me connected LOGICALLY to the previous clause...may be m not able to understand the proper meaning here so please help!!!

Hi,
I believe 'it' refers to the subject 'the number'. You can check Ron's post on MGMAT forums for further clarifications.
