A middleweight black hole weighs in at roughly 500 solar masses, hundreds of times more massive than the lightweight black holes produced by the collapse of individual stars, but thousands or even millions of times less in its mass as the heavyweight giants that lurk in the centers of galaxies.
(A) thousands or even millions of times less in its mass as
(B) it is thousands or even millions of times less massive as
(C) thousands or even millions of times less massive than
(D) yet it is thousands or even millions times less massive than
(E) yet it is thousands or even millions of times less in its mass than
This question is based on Comparison.
The sentence draws a comparison between a middleweight black hole and lightweight and heavyweight black holes on the basis of their weight.
In Option A, the comparison is not parallel as the comparative word ‘as’ cannot follow the adverb ‘more’. Furthermore, the phrase ‘less in its mass’ is wordy and awkward. So, Option A can be eliminated.
Option B also contains the same error as Option A. The adverb ‘more’ cannot be followed by the conjunction ‘as’. So, Option B can be eliminated.
Option D contains the redundant conjunction ‘yet’. Since the conjunction ‘but’ is already present, the conjunction ‘yet’, which conveys the same meaning, is unnecessary. The phrase “it is” is also unnecessary as the subject “a middleweight black hole applies to this phrase also. So, Option D can be eliminated.
Option E repeats the errors in Option D and Option A. So, Option E can also be eliminated.
Option C contains the appropriate conjunction ‘than’ and is concise. Therefore, C is the most appropriate option.
