The supervisor will review your proposal and respond ___ two business days.
答えを見る
正解: C) within
The meaning is 'within two business days' — inside a span of time, so 'within' is correct. 'By' marks a single deadline point and doesn't combine well with a length like 'two business days'. 'Until' marks the endpoint of continuation, and 'during' means 'at some point within a specific period' (during the meeting).
