TPO4 鹿的那題 - 英檢

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


怎麼想都覺得是2啊
不然鹿何必遷徙

動物冬眠就是因為沒食物才冬眠啊

鹿不冬眠所以要找食物 所以遷徙到低地

這個邏輯是對的吧?

正解三說winter讓鹿更所以容易找到食物這更牽強吧

題目又沒有指名low land的winter

就算食物都被風掃下來

比起其他季節 winter怎麼可能"更容易"找到食物

@@好奇怪...
