North American cicadas always garner attention when they come above ground at the end of their 17-year life cycle, but in no case were they as well studied as
was their emergence during the 1920s, when the naturalist William T. Davis studied them in detail.
(A) was their emergence during the 1920s
(B) had their 1920s emergence
(C) in their emergence during the 1920s
(D) their emergence during the 1920s was
(E) their emergence during the 1920s
Hello!
Option A uses
'was their emergence' which is not correct.
Option B uses the word 'had', it does not go well with the sentence in terms of the usage.
Option D uses
'was' at the end; there is no need of using that word.
Option E is fine to an extent, but fails to use the right preposition
'in', so eliminate that as well.
Option C correctly uses the preposition and has no errors.
