这题正确答案应该是: jay 春天时跟另一种鸟飞回北方。
我今天在PREP上刚好做到这题,答案confirmed.
考试加油~
明天考,问下一道逻辑gg:
Every fall Croton's jays migrate south. The jays always join flocks of migrating crookbeaks with which they share the same summer and winter territories. If a jay becomes separated from the crookbeaks it is accompanying, it wanders until it comes across another flock of crookbeaks. Clearly, therefore, Croton's jays lack the navigational ability to find their way south on their own.
Which of the following, if true, most weaken the argument above?
Ans. Croton's jays lay their eggs in the nests of crookbeaks, which breed upon completing their southern migration.
