In order to conserve the energy and heat they need to spend the entire winter sitting motionless over incubating eggs, male emperor penguins huddle over the nests in groups, thereby reducing the rate at which they burn energy so that it is 25 percent lower than it would be for isolated birds.

(A) thereby reducing the rate at which they burn energy so that it is 25 percent lower than it would be for
(B) thereby reducing their rate of burning energy until it is 25 percent lower when compared with
(C) and they thereby reduce by 25 percent the rate they burn energy, as compared to what it would be with
(D) which thereby reduces by 25 percent their rate of burning energy, when comparing them to
(E) which thereby reduces the rate they burn energy so that it is 25 percent lower than

In order to conserve the energy and heat they need to spend the entire winter sitting motionless over incubating eggs, male emperor penguins huddle over the nests in groups, thereby reducing the rate at which they burn energy so that it is 25 percent lower than it would be for isolated birds.

A)thereby reducing the rate at which they burn energy so that it is 25 percent lower than it would be for
B)thereby reducing their rate of burning energy until it is 25 percent lower when compared with
C)and they thereby reduce by 25 percent the rate they burn energy, as compared to what it would be with
D)which thereby reduces by 25 percent their rate of burning energy, when comparing them to
E)which thereby reduces the rate they burn energy so that it is 25 percent lower than

Lets eliminate to get closer to the correct answer. My thought process would be something like -

To conserve something and something.. penguins huddle in groups....(incomplete) -->

I see these patterns -
reduce, reducing, than, compare

Now to minimize time its better to look at those options first which have a higher probability of being correct. Once we feel that its right, we'll try to find errors in other options to support our choice.
A B C D E
than is better than using compare. A and E have it. In E which points to groups. Strike off E. A looks fine. Keep A.
A B C D E
We are left with B, C and D. Compared to is wrong idiom here. Compared with is correct.
Remember, we use compare with for similar things and compare to for unlike things.
C and D are off the ring. C is a disaster if spend some more reading it.
A B C D E
Best choices A and B so far. Usage of than is better than compare. Its more concise. Probability of A being correct answer looks higher. Select the option A, and read B again before confirming.
Wait a min, B is comparing apples to oranges. burnt energy 25% lower than isolated birds? A is the winner!
A B C D E

Mun,
Always ask yourself one question . Whether the result is caused by the subject or the action did by the subject. Here emperor penguins did not reduce the rate . It is the huddling act that did the rate reduction.

With this options C, D, & E are ruled out.

In option B it is given as their rate which is wrong.

Option A) is right.

A)thereby reducing the rate at which they burn energy so that it is 25 percent lower than it would be for -- Correct, but I do not like use of so that in this context I would prefer such that instead. I feel Penguins dont know how much percentage energy they will save they just do so because they feel good.
B)thereby reducing their rate of burning energy until it is 25 percent lower when compared with -- when compared is not right.
C)and they thereby reduce by 25 percent the rate they burn energy, as compared to what it would be with -- winner of most awkward gmat prep options.
D)which thereby reduces by 25 percent their rate of burning energy, when comparing them to -- nearest nouns are nests or groups plural -- but verb reduces is singular
E)which thereby reduces the rate they burn energy so that it is 25 percent lower than -- same as D.

CORRECT
B)thereby reducing their rate of burning energy until it is 25 percent lower when compared with
"until" is not properly used, "when compared with" is unidiomatic (it should be "compared to")
C)and they thereby reduce by 25 percent the rate they burn energy, as compared to what it would be with
"thereby " is misplaced, the comparison is not logic: "they burn" and "it would be"
D)which thereby reduces by 25 percent their rate of burning energy, when comparing them to
E)which thereby reduces the rate they burn energy so that it is 25 percent lower than
which refers to "groups", wrong

whats the difference between thereby reducing and they thereby reduce?

In option D and E , which is modifes groups . it is incorrect.

In option C" and "coordinate conjunction used.
it must be used two combine two independent clauses but not for modifier before.
would be for is idiomatic , would be with is unidiomatic.

In option B lower used but not followed by than.

It is one of the key marker if we want take away in sentence correction such as lower, greater,more, taller and higher must
followed by than most no of times.

If we see some other compartives , for instance, superior, inferior , exterior and interior should follow with preposition "to."

Apart form this , we use compared to for similar items. compared with for two different items.
so it is also wrong in B.

So option A is correct.

This is incorrect. Its the other way around.
compare with - similar things
compare to - unlike things

Your Explanation for B is wrong.lower and compared are not redundant at all.The problematic thing is the referrant for "their" which could be nests too.plus "compared with isolated birds"is problematic.The rates should be compared.We cant compare rate of burning energy with isolated birds.
