原文：Student 1: What’s wrong with Asian honey bees? Are they so different from Australian bees? GRANT: Well, in fact, they look almost the same, but they are infested with mites – microscopic creatures which live on them, and which can seriously damage our own home-grown bees, or could even wipe them out.
本题讨论的对象是 Asian honey bee，在句子开头就用了代词 they 来替代 Asian honey bee，来引出后面的答案句 they are infested with mites。
而陷阱就容易出现在代词所指代的对象到底是不是题目所讨论的对象。看后面的那两个which 指代的是不是本题的 Asian honey bee 呢?事实上，不是。
