Registration for the trade fair closes ___ the fifteenth of June.
答えを見る
正解: B) on
'The fifteenth of June' is a specific date, so 'on' is correct. 'In' is used for broader periods like months, years, or seasons (in June). 'At' is for clock times (at 5 p.m.). 'By' means 'no later than' and marks a deadline, but here 'closes' is a single point-in-time action, so the date-marking 'on' is the right fit.
