单选题 To deal with the problem in recent years, Straub and her workmates have to ______.

A、 ask different kinds of families for help
B、 limit the number of the exchange students
C、 borrow much money to pay for the costs
D、 force some families to accept students

【正确答案】 A

【答案解析】推理题。我们从上一题的分析中得知近些年学生的交流工作的实施变得困难了。根据文中“．．．exchange programs are increasingly broadening their appeals to include everyone from young couples to retires。”交流项目正在拓宽它的范围，从年轻夫妇到退休老人。所以我们可以推断出，Straub和她的同事们要寻找不同类型的家庭来接受这些孩子。[A]项正确。
