{A} - INCORRECT; "and he earned them" - "and" symbolizes that these two are different events. -> Meaning issue.
{B} - INCORRECT; we don't need adverbial modifier; "time that aviation" is wrong - "time when aviation" is correct
{C} - INCORRECT; "these" is wrong usage; "time where" is wrong
{D} - INCORRECT; "such" is changing the meaning; "time when" is better construct.
{E} - CORRECT;

Hello!

The following is what Ron said regarding your doubt:

"i'm with you on this one; i'd likewise prefer a wording such as 'in less than 35 years after...', because, in my opinion, it better conveys the idea that the migrations took place continuously over the 35-year period. just plain 'less than' seemed to me, and possibly to you as well, to suggest that the migrations might have occurred all at once.

in any case, though, you've got to remember that correctness trumps clarity (and definitely trumps concision as well). therefore, differences in wording, such as this one, are trifling in comparison to actual errors in usage, grammar, diction, or idiom. i think both of us will agree that there is no idiom error in the wording chosen here; it's just a somewhat awkward wording (a situation by no means uncommon on the real test)."
