Birds need so much food energy to maintain their body temperatures that some of them spend most of their time eating. But a comparison of a bird of a seed-eating species to a bird of a nectar-eating species that has the same overall energy requirement would surely show that the seed-eating bird spends more time eating than does the nectar-eating bird, since a given amount of nectar provides more energy than does the same amount of seeds
The argument relies on which one of the following questionable assumptions
(A) Birds of different species do not generally have the same overall energy requirements as each other
(B) The nectar-eating bird does not sometimes also eat seeds
(C) The time it takes for the nectar-eating bird to eat a given amount of nectar is not longer than the time it takes the seed-eating bird to eat the same amount of seeds
(D) The seed-eating bird does not have a lower body temperature than that of the nectar-eating bird
(E) The overall energy requirements of a given bird do not depend on factors such as the size of the bird, its nest-building habits; and the climate of the region in which it lives

此题呢，答案是C。我选的E。我是觉得这个题是个果因结构的假设题。所以就采用not+他因削弱的方法。
结果我觉得E挺好啊.... not后面加了一串他因，狂喜！一对答案，哭~~~~

我是觉得C呢和题目中的条件相悖。既然体重都说了吃seed的鸟比吃nectar的鸟花的时间长。C项重复这个意思：吃nectar的鸟鸟的时间并不比吃seed的鸟鸟长...，完全就是一个重复的premise嘛...咋就成了assumption呢。
