Answer:
start
Step-by-step explanation:
With the "start" of winter, when part-time residents often move away, many shops in resort towns curtail their hours of opening to three or four days a week.
Winter is the coldest season of the year with the experiencing of snow and frost. During this season, there is shorter days and longer nights. The sun hardly shines warmer in those seasons.
So as a result of this season, part-time residents often move away. This makes curtail shops to open three to four hours in resort towns.
