Why not option “e”?
In no other historical sighting did Halley’s comet cause such a worldwide sensation as did its return in 1910-1911.
A. did its return in 1910-1911
B. had its 1910-1911 return
C. in its return of 1910-1911
D. its return of 1910-1911 did
E. its return in 1910-1911
Options A,B,D and E are wrong because the comparison is between the comet and its return.
Only option C makes the right comparison. Read it as “In no other historical sighting did Halley’s comet cause such a worldwide sensation as (it did) in its return of 1910-1911 . The “it did” here is implied.
Hope this helps!
