对于OG对C选项的解释:
creating seems to refer back to lying; if used as a participial, creating would have to be preceded by a comma.我想是这样的:首先可以肯定的是:不管是that creates/create, who creates还是creating逻辑上都没有修饰到individual的歧义,就如OG对E的解释:"
reactions is not a person,
who is the wrong relative pronoun to use",即便用了who,也不是指代individual,而是指代reactions,因为指代individual逻辑上不合理,测谎仪不是对某类特定的人才有用。虽然GMAT不要求专门的知识,但是常识性的逻辑推理还是需要的。
续观C选项:
The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual creating, in turn, unconscious physiological responses.
C选项里creating与emotional reactions被in an individual隔开,造成creating语法上与reactions脱节,那么就只有做状语修饰最临近的分句了,如果没有in an individual隔开就可以了(*见下面类似题),;但问题是creating前面少了逗号,所以语法上依然通不过。而且即便creating前面加上逗号用作分词表示伴随结果,比起A选项还是差了一点,它只表明了产生physiological responses是前面"lying造成emotional reactions的结果",而漏了一层含义:该physiological respones是emotional reactions产生的;A表明该逻辑链更为清晰:lying先造成了emotional reactions,emotional reactions再接着产生了physiological responses。不过即便有这样的不清晰(less successful at clarifying the chain of events),如果C选项creating前加上逗号也是没有语法、逻辑上的错误的。
对于"如果没有in an individual隔开就可以了",见下例:
By a vote of 9 to 0, the Supreme Court awarded the Central Intelligence Agency broad discretionary powers
enabling it to withhold from the public the identities of its sources of intelligence information.
(A) enabling it to withhold from the public
(B) for it to withhold from the public
(C) for withholding disclosure to the public of
(D) that enable them to withhold from public disclosure
(E) that they can withhold public disclosure of
key: A
OG解释:In this correct sentence, the underlined phrase clearly modifies powers; it refers to the Central Intelligence Agency. To withhold from the public is concise, idiomatic, and clear.
本体enabling紧接所修饰成分,所以没有问题。
