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 decoy 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
我個人選2 但答案是3 為什麼不能選2呢? 感謝大家
ps. 黃金29篇的答案都是對的嗎?
