答案应该为E吧，A、D中it指代有问题；B中rather than 前后比较不对等啊。只有E没有错误啊！

e,A意思不对，rather than 结构不平行

支持A，A里面的it不可能在逻辑上指代Sun,所以只会指代body heat.

A looks better than E which put two different things into comparison

逻辑平行，比语法结构平行更重要。如果结构平行，但是逻辑不通，也不可以。

这道题的逻辑结构是 体温的获得是 从太阳那里获得，而不是从燃烧卡路里获得。

虽然结构上没有严格对称，也只有C是逻辑上平行的。通过 from....and not from .....避免了歧义，清楚了说出了本题的逻辑意思。。

其他选项 平行部分都在逻辑上说不通，都产生了歧义。 仿佛在说，获得体温可以通过太阳， 燃烧卡路里也可以通过太阳， 等等。

大家可以体会一下。

Rather than shows preference not alternative. so i think rather than will not be used here. instead of hints at parallelism before and after it. E options is parallel to the earlier portion. "drawing their body heat = body heat generated" & "directly from the Sun = by burning calories"
I hope this clarifies.
