题目选项分析

The prairie vole, a small North American grassland rodent, breeds year-round, and a group of voles living together consists primarily of an extended family, often including two or more litters. Voles commonly live in large groups from late autumn through winter; from spring through early autumn, however, most voles live in far smaller groups. The seasonal variation in group size can probably be explained by a seasonal variation in mortality among young voles.

Which of the following, if true, provides the strongest support for the explanation offered?

【选项】Snakes, a major predator of young prairie voles, are active only from spring through early autumn.

选项是否正确?

vole主要的捕食者蛇只在春夏活躍,所以春夏vole少,因為被吃了,合理
