Ms. Tanaka has worked at the Osaka branch ___ more than ten years.
答えを見る
正解: C) for
What follows the blank, 'more than ten years', is a span of time, and length of time takes 'for'. 'Since' marks a starting point (since 2015) and doesn't combine with a length-of-time phrase. 'During' means 'at some point within a specific period' (during the meeting) and doesn't pair with a quantity expression. 'While' is a conjunction and needs a clause (subject + verb) after it, not a noun phrase.
