Paragraph 2: Nearly any kind of plant of the forest understory can be part of a deer's diet. Where the forest inhibits the growth of grass and other meadow plants, the black-tailed deer browses on huckleberry, salad, dogwood, and almost any other shrub or herb. But this is fair-weather feeding. What keeps the black-tailed deer alive in the harsher seasons of plant decay and dormancy? One compensation for not hibernating is the built-in urge to migrate. Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. Even with snow on the ground, the high bushy understory is exposed; also snow and wind bring down leafy branches of cedar, hemlock, red alder, and other arboreal fodder.

2. It can be inferred from the discussion in paragraph 2 that winter conditions
􀂅 Cause some deer to hibernate
􀂅 Make food unavailable in the highlands for deer
􀂅 Make it easier for deer to locate understory plants
􀂅 Prevent deer from migrating during the winter

我选的a 一个答案说是b一个说是c 到底怎么回事？？我觉得b好像靠谱 说是要infer嘛 又觉得a好 Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. 这句应该是从高迁到低的意思吧 看了一个解释说是从低到高 郁闷这个阅读超时了 还错了3个。。。

a应该不对吧，这种鹿不冬眠+compensate不能infer其他鹿冬眠吧，可能是其他动物冬眠，author用deer和其他动物比较吧，我选的B，没觉得C对

看了一些老帖子的解释为何选C，觉得挺搞笑的。。。。ets答案出错也不是一次两次的事，不能答案是什么就怎么讲解吧。。。求真正大牛来解释下

“Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall.”
感觉这句话说的迁徙的方向并不一定是从高地向低地，只是从植株高的地方迁到低地而已，查了一下webster，其中对于browse名词项的第一个解释是tender shoots, twigs, and leaves of trees and shrubs used by animals for food
我一开始也选B,后来看这句话时觉得不对。
不知道这样理解正确与否（只看了这段，没联系上下文）
