问题 When is the flushing scheduled to be completed?
  
The Lester Water Department is flushing the municipal water system this week, starting Monday, between the hours of midnight and five A.M., and lasting through Friday morning. Flushing is performed every spring as regular maintenance to remove mineral deposits and sedimentation that has collected over the winter months. Residents are asked to let the cold water run from the tap for a full minute to ensure that it is clear. The water may be temporarily discolored but it is safe to drink and to use for cooking. For more information, call three-five-seven, five-four, three-nine.

选项 A、Let the water flow from the tap before using it
B、Fill containers with fresh water prior to the flushing
C、Report any discoloration or other problems immediately
D、Boil the tape water for at least one minute before drinking it

答案A

解析 短文中间部分提到“tap for a full minute to ensure that it is clear”,为确保水质干净,市民需要把水龙头打开一定时间,表达“使用前请放一段时间的水”含义的(A)为正确答案。
