A.    wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is
B.    wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be
C.    wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be

E.    total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is
  Answer:
comparing value of meat，为什么后面不要用fat 和他对称，而是用animal做主语啊。。。答案是B，我选的E

comparing xxx 修饰的是study吧。说明这个研究是干嘛的。
E 中they错了貌似。

E错误太多了
1比较对象成total fat了
2比较从句怎么看怎么别扭，前面是主系表+状语，后面照理来说应该是介宾比较，这个句子即使改成了than in livestock fed .. 意思上也有问题。
3 代词指代
4 more of是修饰have的，后面应该接个类似名词的成分，E后面又出现了一个their fat is 的主谓结构，有点莫名其妙。

答案应该是C吧~
虽然我也选的B

A than前后不平衡，they指代不清
B 是想用主语做比较，但是不平衡。如果变成主语比较应该是：wild animals have less total fat than livestock fed on grain 【do】 and 【have】 more of 。。。。
C 正确。是个宾语比较：fat 与 fat 比
DE 错同A

我也觉得是c  b里会有歧义，即fat和livestock比，应该加个do
