B有歧义，我可以理解为 wild animals have less total fat than livestock fed on （grain and more of a kind of fat thought to be）
也就是，野生动物比家畜的总脂肪少，那种家畜吃谷物和某种脂肪

comparion 比较对象不一致 拿fat和livestock 比较
 LZ要分清楚逻辑上与形式上他要比较什么
    你看C项，就很清楚的把wild animal的fat 和 livestock的fat 进行比较

michellefyj

同意B选项确实有歧义，但是我觉得C选项中，把wild animal 和 that of livestock并列起来，更错。所以我倾向于选C了。

michellefyj

倾向于选B，不好意思打错了。

sorry I can't type Chinese now...

Choice C is perfectly right. The right way of putting the first part of the sentence could be:
1. wild animals have less total fat than livestock DO
2. wild animals have less total fat than that of livestock.....

in the first case, the compared objects are 'wild animals have total fat' and 'livestock do (have total fat)'
the second case compares 'fat'

Hope I made this clear...

不是，正确答案是B

选项分析：

A. they没有指代对象；

B Correct. 是主语部分wild animals 和 livestock fed on grain在比较。在此省略了相同的谓语和宾语（因为不会有wild animals have livestock的歧义，只要逻辑上基本成立，GMAT并不认为所有没有补出谓语动词的形式都是”ambiguities”；"less X and more Y"是 idiom correctly.

C. 在livestock前加上that of…比较的对象是animals has less fat和that，that指代fat，而事实上比较的应该是wild animals和livestock的属性，即拥有fat的多少，所以than后面也应该用平行的句式，即主谓宾形式；
