例3. According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than [that of] livestock fed on grain and more of a kind of fat thought to be good for cardiac health.
That of不能省略,因为比较的是fat。
--------------------
想问下这句话不太对吧,不能用wild animal和 fat比较吧,OG的答案选的也不是这个
