RON: you've learned a lesson here: the gmat's preference for that 'do' is not absolute. from a 100% strict semantic viewpoint, i agree with you here: there's technically an ambiguity. however, we now have evidence, in the form of this problem, that the gmat doesn't consider ALL of these 'ambiguities' as truly ambiguous. rather, provided that the 'second meaning' is sufficiently absurd AND nonparallel (note the obvious logical nonparallelism of compairing total fat to livestock), it's ok to eliminate the 'do'. sigh. remember, we don't make the rules; they do. but with each problem like this one that you study, you'll have a better idea of exactly what their rules are.
wild animals have less total fat than livestock fed on grain (do) .....
还原:wild animals have less total fat than livestock (do) fed on grain 后面有定语fed on grain, do 前移 ie. than do livestock fed on grain 省略的do 就是have,语义正确
比较do也可倒装,也可省略 后半部分没有比较,a kind of fat 和 total fat 平行
Isn't B incorretly saying wild animals have less fat than wild animals have livestock I thought for proper comaprision we need verb in the second part of comparision something like - wild animals have less total fat than do livestock.

比較用法 比主詞 wild animals vs livestock
wild animals 和livestock比较,more of a kind of fat 前面省略了 have
wild animals 和livestock比较,more of a kind of fat 前面省略了 have
真心sign, 按照平时的语法逻辑,这里的livestock是与total fat对称的,应该是错的。看来还是不能只依赖这一点就判断答案。
