The army cutworm moth is a critical source of fat for as many as a third of Yellowstone National Park's grizzly bears; they overturn rocks to find them, as many as 40,000 per bear in a single day.

bears, overturning rocks to find them, as many as

bears, which overturn rocks to find the insects, as many as
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
as many as 和up to不是考点吗……这题应该用排除法
A they和them指代不同名词
B 分号后要加完整句子
C overturning逻辑主语变成moth而不是bear
D 同样指代错误
E 觉得which有点怪，但"who" is used for humans，sometimes "who" is used for animals that are personified (such as people's pets), but the standard is "which".
ron：the gmat will only do the second of these,so you can rest assured that the personal pronouns (who, whom, he, she, him, her) will be used only for human beings.GMAT里只会考察who指代人，不会考察动物拟人化，所以指代动物时统统用which
them指代错误，分好后加句子
"who" is used for humans.
sometimes "who" is used for animals that are personified (such as people's pets), but the standard is "which".
这道题我错误地选了B.
分析B选项，“up to”应该本身没有问题吧？错误在于，bears后面应当跟定语从句而不是伴随状语？因为修饰的是bears而不是一种状态。
B选项，我是通过Sentence Structure有问题排除的。semi colon后面应该是一个完整的句子，错在无Subject的 Fragment
A选项是不是因为they指代不同，所以错了？
B选项分号后面缺少主语，你说得对！A选项出现they和them，指代不明，我是这么排除掉的。“它们找它们”，这种表达方式是有问题的。
我的理解是，如果按照intended meaning，翻译过来是“灰熊翻开石头找蛾”，但是，一个句子中出现了同一个代词，they，不同指代对象。这个就Ambitious了。印象里，貌似没有出现过一个句子有两个以上的代词的，是不是就是因为会指代不清？？你有没有遇到过一个句子出现两个以上代词的情况？
听完RON的视频，我懂了。
当选项中出现代词保留了原有指代名词，代词是考点。
IF you see a pronoun taken out and replaced by a specific noun, you should strongly suspect that the pronoun is incorrect. (although you should still check the pronoun rules)This is intended to mean “moths”, but it can’t (because “moth” appears as the singular form)
代词的指代肯定是考点，通常出现代词的，需要在句中找到对应的清晰的指代对象。你问我有没有遇到过句子出现两个以上代词，一下子想不起来例子耶...出现形式主语的算不算？形式主语当中的"It"不存在指代问题。
针对这个句子，我的理解是：同一个代词肯定不能指代两种事物哇。Otherwise it'd be ambiguous, as you said.
突然想到，代词的指代不清甚至不是绝对错误，不能上来直接排除，得先看句子结构和成分。代词和其指代对象的单复数不一致属于重大语法错误。
Got it！ 等我看看以后会不会再碰到一个句子，出现两个一样的代词的题目。嗯。分享一下SC做题心得，顺序可以是：1）Intended Meaning What is What？ What is modified？ 2）Is it a Sentence（Runon or Fragment）3）What are the Splits（Find the basic ones such as Agreement，Parallelism，Modifier，Pronoun， and verb tense）4）Reread to check if there is redundancy or Ambiguity
Thanks for sharing! I always put grammatical construction(i.e. sentence structure) and logical prediction in the first place, and then to look at agreement, parallelism, verb forms etc, and the last is to pay attention to diction, idiom and rhetorical construction.
同一个代词不能指代两种事物，就像同一个句子不能出现两个主语，否则破坏Parallelism了。
比如这道：To Josephine Baker, Paris was her home long before it was fashionable to be an expatriate, and she remained in France during the Second World War as a performer and an intelligence agent for the Resistance.
不知道这么类比恰不恰当，感觉其实所谓的RULE最终都化为了Whether this sentence‘ s meaning make sense or not？
你是不是二刷这道题了哈哈～同意你说哒，在句子改错里，所谓语法规则应该都是为了表意精确服务的。
不是哈哈！是做那道题时想到这里来了。话说同学你是在美国考G嘛
不是哎，我在国内考呢～原来你是时差党;)
并不哈哈 我也是在国内考
加油加油，祝早日杀G成功！刚发现这题被我俩的讨论霸屏了，也是棒啊哈哈～
哈哈！同祝杀G成功！BTW，安利一个帖子：https://forum.chasedream.com/thread-739174-1-1.html
