"One of the big reasons behind workers' lack of sleep is the work itself"
What, if any changes should be made to this sentence in the article? (All changes are replacements for "big reasons behind".)
A: NO CHANGE
B: main things leading up to
C: huge things about
D: primary causes of
I answered A because it seemed to make sense and the rest of the article didn't seem that formal.
The real answer is D with the reasoning being that "choices A and C are incorrect because both rely on colloquial language, specifically "big" and "huge," which strays from the formal tone of the article."
Are the words "big and "huge" colloquial?
