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.
------------------------------------------
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.

Then I am fine, thanks for sharing this important sematic point.
Let's end this thread, though a good one.

我的疑问和rx_11一样，而我觉得tim没有解释清楚：

Hi, instructors

Thanks very much for your reply. But maybe I did not make my question clear.

My question is why the comparison is incorrect in this sentense.

"Wild animals have less total fat than the total fat of livestock"

Ron has explained that this comparison is wrong because we cannot compare "Wild animals" & " livestock" when "livestock" are in a prepostion in the second part. But I think we can compare "the total fat" of the two animals as the underlined part shows.

According to this example, I find that if a sentense is following the Subject+Verb+Object structure, then the sentense is always used to compare the subject, not the object. Is that true??

Moreover, I find this rule seems to be able to apply to all comparisons and I could not find out any exceptions. Experts please confirm it. Thanks very much!

Best regards.

rx.

tim replys:

rx, answer choice C says that wild animals have less of one thing than they do of another. It also makes clear that these things are “total fat” and “total fat of livestock”. Let’s say you could measure how much “total fat” wild animals have. You’d still find it rather difficult to measure how much “total fat of livestock” wild animals have – although I’d guess it’s zero..

As to your other question, there is no such general rule..

看到这个贴子的最下面Ron说：
this problem is most likely not from GMAT PREP (the sole subject of this folder), so the thread is now locked.

感谢指正；
另外我发现了更加权威的例句证明确实可以不用补充动词，一直以来认为的主语比较需要补动词是错误的。

我想先问你，你为什么排除第一题的E选项？为什么排除第二题的C选项？

因为e选项比较的是protein和wheat ，但是第二题我选的就是c选项 而正确答案为B呀

能否分享一下你发现的例句及其来源呢？

这题我和chineuro 讨论了很多，你可以看看，其中也有manhattan的解释。

我在牛津词典中发现在了这么一句话；
Nobody understands the situation better than you。谁也不如你了解情况 。它并没有说than you understand.
其实更为重要的是这里根本就不能补全

以前的论述看起来还是有待进一步完善，再一次劝大家不要去怀疑Gmat的答案，它的答案不但正确而且正确绝对正确。

I have more green apples than red apples ,不知道这样说对不对？ 如果对为什么不是than red apple have green apple? 如果不对？那我有的绿苹果比红苹果多应该怎么说呢？

谢谢分享！
我觉得
I have more green apples than red apples. 这句话是正确的，
实际上是：
I have more green apples than（I have）red apples. 同时省略主谓，是可以的

如果是这样的话他有两种省略方式，就又回到了只能通过逻辑来判断有无歧义了

我建议还是在具体的题目中采用排除法来做题，因为这种问题的分类并不是十分明确
