问题 What is the most expensive type of call?
What can you do if the international line is engaged?

选项 A、Ask the operator to call you back later.
B、Make a "person-to-person" call.
C、Call back outside office hours.
D、Wait and call again when the line is free.

答案A

解析 从文章第二段最后一句话可知,If the inter-national line is busy,you can reserve(留下)a call,explain the number you want and the operator will call you back when the line isfree.要是占线的话,你可以留下电话,等空闲时接线员会通知你的。所以正确的答案为A。
