请教一道逻辑题

cx89916

Which of the following most logically completes the passage?
Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators.  In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.

A.    large moths are generally able to maneuver better in flight than smaller moths
B.    large moths are proportionally much more common in warm climates than in cool climates
C.    small moths are more likely than large moths to be effectively camouflaged while on vegetation
D.    large moths typically have wings that are larger in proportion to their body size than smaller moths do
E.    most predators of moths prey not only on several different species of moth but also on various species of other insects
还请大牛们分析一下为什么选D，谢谢

选B 吧  很显然嘛

我选的也是B啊，但答案是D，难道答案错了

这个题确实答案是B，文章提到的是温度低--被吃掉，那么只能是热的地方比冷的地方的这个物种多了，GWD给的答案好像有问题

Please read the last sentence...

Large moths can fly faster than small ones-> which explained why...

Only possible explanation is its Wing

CX同志不要搞混了 1. which指代的是： they have higher temperature.
                             2. logically speaking,  逻辑关系怎么会是 fly fast---> big wings呢？  推理关系反了，就好比我长的高，所以推出我天天喝牛奶，可笑吧

                             3.更何况，big wings 和 fly fast真的是 necessarily correlated吗？ 谁说翅膀大就是快。
GWD的答案其实有待商榷的~~
