I fail to understand that why so many replies are discarding the option A for the reason that it is not parallel. There seems to be a correct parallelism in both A and B, but not at the place where the option A is being faulted at, for missing parallelism :
In both A and B, the correct parallelism lies at the highlighted place :
A:
The defective thermometers will sometimes fail to register
a fever when it is present and indicate that there is one when it is not.
B:
The defective thermometers will sometimes fail to register
a fever when it is present and indicate that one is present when it is not.
Experts, could you help as to why B is preferred to A ?
VeritasKarishmaMentorTutoringAjiteshArunHello,
abhishekmayank. I agree that parallelism is not the offense in (A). We can just replace
one with
a fever, though, and see why (B) would be preferred:
A. The defective thermometers will sometimes fail
to register a fever when it is present and indicate that there is a fever when it is not.
B. The defective thermometers will sometimes fail
to register a fever when it is present and indicate that a fever is present when it is not.
You want to look for a direct answer to the question,
What does the thermometer indicate? The answer is
a fever, not
there is. Moreover, the end of choice (A) forces us to do a little backtracking to qualify the meaning of
there is a fever when it is not [present]. Compare this to the straightforward expression of vital meaning at the tail-end of (B):
a fever is present when it is not. (B) wins, hands down.
I hope that helps. Thank you for bringing my attention to the question.
