the most favorable lactions for the growth of glaciers,rather than being the cold.dry polar regions, would be instead the cool,moist middle latitudes,where there is abundant precipitation and where it is cold enough to allow some snow to accumulate year by year.

a)

b)glacier are not the cold,dry polar regions but the cool,moist middle latitudes,

c)glaciers are the cool,moist middle latitudes rather than the cold,dry polar regions,

d)obv. error

e)obv. error

答案说是b，说c改变原句意思，但是where从句根据常理应该是修饰polar regions的吧。。。。。。snow就是在polar regions accumulates的吧（虽说glaciers的适宜环境是cool and moist latitudes也不怎么合理）

大家给点思路。thx

看看后面说的是什么：where there is abundant precipitation足够的雨水怎么会是修饰the could,dry polar regions的呢~ 而修饰the cool, moist middle latitudes就非常合适了。

这里考的是就近修饰的问题。lz可能是没有看懂句子的意思，现在gmac越来越倾向于根据句意选择合适的句子结构了。
