A Difficult Question Four girls went to school every day by taxi. One day one of the girls said , “ There’s a test this morning . Let’s get to school late . Then we won’t have to take the test . ” “ What can we tell the teacher ? ” one of the girls said . “ He’ll be angry , We’ll need a good excuse . ” The girls thought for several moments , then one of them said , “ Let’s tell him that our taxi had a flat tire . ” “ That’s a good idea , ” the other girls said . “ We’ll tell him that . ” They arrived at school an hour later . The test was finished . “ Why are you late ? ” the teacher asked . “ You missed the test . ” “ Our taxi had a flat tire , ” one of the girls said . The teacher thought for a moment , then he said , “ Sit down , one of you in each corner of the room .” The four girls did this . Then the teacher said , “ Write on a piece of paper the answer to this question : Which tire was flat ? ” 四个女同学天天一起坐出租车去学校。 一天，他们其中一位说，“今天早晨有场考试，我们一起迟到。到时候我们就不用考了。” “我们怎样对老师解释？”另一位说，“他会非常生气。我们需要一个好的理由。” 她们想了一会，其中一位说，“我们告诉他，我们的出租车有一个轮胎漏气了。” “那真是个好主意，”其他几位说。“我们就告诉他这个。”她们迟到了一小时。考试已经结束。 “为什么你们迟到？”老师问“你们错过了考试！” “我们的出租车有一个轮胎漏气了！”一位女同学说。 老师想了一会，说，“坐下，每人到各自的一个角落” 四个女同学按要求坐好。 老师说，“把这个问题的答案写在一张纸上：四个轮子中，哪个漏气了？”
