    "the set of airline flights from New York to New Delhi, the set of nonstop airline flights from New York to New Delhi"
    这里自己怎么想都是第二个集合是第一个的真子集。但是事实上是
    "The first is a subset of the second, but the second is not a subset of the first"

    到底是英语方面出错还是关于航班的理解上出错还是其他的,有没有人愿意告诉我?
    因为问题很蠢就没发问与答节点

    @archbishop 原文是从《离散数学及其应用》第七版“影印版”里摘出来的,书附带的答案也确认了很多遍就是这样。实在不敢相信一本数学书会有这种错误
