题目分析：
略
选项分析：
A选项：代词they没有指代对象。
B选项：Correct. 本选项在逻辑和语法上均是正确的。
C选项：fat of a kind需改为a kind of fat。a kind of是一个固定搭配，表示某一种，不能拆分。of a kind表示“同一类，相似的”，显然不符合本题的含义。另外，这里的that of略有赘余的嫌疑，虽然可以比较两种动物的脂肪，但比较两种动物已经足够清楚，所以这个that of可以不必要添加。
D选项：比较对象不对等，应该比较的是野生动物和家养动物。fat of a kind需改为a kind of fat错误同选项(C)。
E选项：代词they的指代错误同(A)。fat is of a kind错误原理同选项(C)。
比较看来也是个原则变化不定的考点呀，没办法，只能硬着头皮去理解去掌握了。
A选项不关比较，they的指代是一个严重问题
B选项：在本题中GMAC认为省略的后半部分是可以在不造成歧义的情况下省略谓语的咯，这跟I eat apple more than you冲突咯，那里GMAC可以认为不行的，但如果从合理角度看，显然人也不会去吃人，这个点暂时mark一下。毕出老师的意思就是对于这种类型的比较没有一贯的原则，只需要按照最合理的比较对象去比较就好了。
C选项比较对象其实不对等了，要对等要把前面改成wild animal's total fat is less than that of livestock
D选项比较对象不对等
E选项中的they指代错误同A
注：of a kind表示同一类，即德州扑克里，three of a kind，就是三张一样的牌； They are two of a kind, and totally unreliable. 意思是他们两个是两类人
a kind of 就是一种，在这里语意应该是一种
