Ticks attach themselves to host animals to feed. Having fed to capacity, and not before then, the ticks drop off their host. Deer ticks feeding off whitefooted mice invariably drop off their hosts between noon and sunset, regardless of time of attachment. White-footed mice are strictly nocturnal animals that spend all daytime hours in their underground nests.

Which one of the following conclusions can be properly drawn from the statements above?

(A) Deer ticks all attach themselves to whitefooted mice during the same part of the day, regardless of day of attachment.
(B) Deer ticks sometimes drop off their hosts without having fed at all.
(C) Deer ticks that feed off white-footed mice drop off their hosts in the hosts’ nests.
(D) White-footed mice to which deer ticks have attached themselves are not aware of the ticks.
(E) White-footed mice are hosts to stable numbers of deer ticks, regardless of season of the year.

Question to experts and to people who cracked GMAT.

How do you decide - to use pretinking or to check options?
Depending on question?
Or maybe you have worked some rules for you, when to use it? Maybe in particular types of questions?

The question above is the bright illustration when it is possible to prethink. I knew exactly, what kind of answer I would be look for. Before staring into the options.

But this skill is weak. I would like to improve it very much.

How do we choose between B and C?

For B, if "deer ticks feeding off whitefooted mice invariably drop off their hosts between noon and sunset, regardless of time of attachment", this means that they might attach to the host 1 second before sunset and then drop off at sunset, consequently not feeding at all. So B makes sense.

Could you please shed some light? Thanks

Since we have to draw a conclusion here, this question is of must be true category.

A. Extreme answer choice with new info.
B. The use of sometimes gives us a 50-50 answer. Sometimes they can feed for longer hours sometimes they only feed for a minute or lesser before sunset. Dropping off their host is a definite action that will take place during sunset. Hence, this answer choice is a strong contender.
C. The ticks start feeding from afternoon till sunset, the time when mice are in their nest (since they are strictly nocturnal). Hence there is a strong probability that the ticks drop off their hosts' in their nests.
D. Could be true & out of scope. It doesn't matter if the mice know or they don't.
E. New information not required for us to answer the question raised in the stem.

Now we have to choose between B & C. We should go for C as it is a sure shot answer.
