单选题
The getaway driver"s garage is protected by an electronic alarm. Four wires lead from the POWER source, but only three of them are connected to the BELL in the middle. To enter the garage without setting off the alarm, Inspector Corner must cut three wires that connect the POWER to the BELL. Which is the wire he needn"t cut?
【正确答案】
D
【答案解析】此题有点类似于走迷宫，沿A线路往下看就会发现它并不通往中间的任何一个BELL，所以A线可以不用切。
