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 do livestock fed on grain and more of a kind of fat they think is good for cardiac health.
A. wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is
B. wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be
C. wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be
D. total fat of wild animals is less than livestock fed on grain and they have more fat of a kind thought to be
E. total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is

答案是B. 但B选项也可以理解为 Wild animals have less total fat than (wild animals have) livestock, 这样不就说不通,会产生ambiguity么?
另外C选项为什么不能理解为wild animals have less total fat than (wild animals have) fat of livestock呢?这样不能算平行吗?

求助啊~~~想不通T_T

OG Explanation
Logical predication; Rhetoricalconstruction
The sentence reports research findings on the comparisonbetween the fat content of wild animals and that of domestic livestock. The mostsignificant error in the sentence is in the phrase they think: the pronoun theyeither lacks a referent or is meant to refer back to wild animals, which would benonsensical.
A,The pronoun they fails to refer correctly.
B,Correct. The phrase thought to be eliminates the most significant error in the originalsentence. Note that while the phrase less total fat than livestock differs from the phrase less total fat than do livestock in the original, either would be correcthere.
C,The resulting sentence is unnecessarily wordy and confusing. The pronoun that is not only superfluous, but it fails to refer back to anything.
D,The resulting sentence makes a nonsensical comparison between total fat and livestock.
E,The resulting sentence is wordy and confusing. It lacks the required parallelismin wild animals . . . in livestock. The referent of the possessive pronoun theiris ambiguous, as is the referent of the pronoun they.

RON: manhanttanprep.com
"that of livestock fed on grain" is  'the ____ of their parents and grandparents'.
for this to work in a comparison, it should be compared with 'young people's ____'.

e.g.,
Because of the tech boom, many young people's net worth is already greater than that of their parents or grandparents.

we don't have that here.

1)我来解释一下OG为什么说B项有没有do都正确;

其实一般GMAT句子中,补出动词的都是可能产生歧义的句子,就是这个动词不补出,这个句子不仅仅形式上会有歧义,更重要的是逻辑意义也会歧义,在这里其实是没有这个语义歧义的问题

wild animals have less total fat than (wild animal have) livestock fed on grain
传统上,我们认为如果不补出动词,就可能产生上面那句这样的歧义,
但是,这个所谓的歧义,逻辑语义根本不同(wild animal have livestock-野生动物拥有家养牲畜??),语义不make sense,所以不能认为歧义;
这就是所谓的比较事物不在一个level(同一个层级)

2)更重要的在于比较comparison的对象上,that在OG认为是没有先行词的,要补出that需要向上面第二个引用框那样的句子才行

赞!答案很清楚~但是我对后半句还有疑问可以讨论一下吗
wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be

这里fed on是修饰livestock的吗?如果如此,应该是需要一个which先行词才说得通啊。
还有and作为连词,后面应该是一个完整的句子才对,然而没有动词不能构成一个句子。要怎么解释呢?谢谢!!

wild animals have less total fat than livestock (fed on grain)  and wild animal have (more of )a kind of fat (thought to be good for cardiac health)

=>缩句到只剩主要成分
wild animals have less total fat than livestock and a kind of fat
以上(……)里面的全部都是不同的修饰成分,

我是这么理解的
野生动物比起家畜有更少的脂肪,并且野生动物拥有的脂肪大多是被认为有利于心脏健康的那种(脂肪)。
