154. Aviation officials have not only failed to determine the cause of the crash, but they have also ignored demands by the pilots union that the investigation should be expedited.
(A) crash, but they have also ignored demands by the pilots union that the investigation should be expedited
(B) crash but also ignored demands by the pilots union that the investigation be expedited
(C) crash but have ignored demands for expediting the investigation by the pilots’ union
(D) crash, but they are also ignoring the pilots’ union’s demands to expedite the investigation
(E) crash: the demands by the pilots’ union that the investigation should be expedited have also been ignored
选b毫无疑问，我的问题是 b …..demands by the pilots union that the…..这里的that 从句应该是修饰demands 而不是pilots 但是它没有紧跟修饰词，请问在语法角度上说到底是不是考虑错误选项的一个标准，因为可以说造成修饰模糊，容易产生歧义

现在很糊涂，很多正确选项横看竖看不顺眼

还有一个例子

174． Believed to originate from a small area on their foreheads, elephants emit low-frequency sounds that may be used as a secret language to communicate with other members of the herd.
(A) Believed to originate from a small area on their foreheads, elephants emit low-frequency sounds that may be used
(B) Elephants emit low-frequency sounds that are believed to originate from a small area on their foreheads, and they may use this
(C) Elephants emit low-frequency sounds, believed to originate from a small area on their foreheads, that they may use
(D) Originating, it is believed, from a small area on their foreheads; elephants emit low-frequency sounds they may use
(E) Originating, it is believed, from a small area on their foreheads, low-frequency sounds are emitted by elephants that may be used
正确答案c, that 从句是修饰 low-frequency sounds 的，但是却没有紧跟它，当中插入了一个过去分词做定语，因为that前有逗号隔开，这种情况下是不是可以说就不会产生歧义，误以为是修饰逗号前的foreheads了呢？

你这个问题是个硬骨头，如果拿GMAT改错作一篇论文的话，应该是个好题目，够研究一阵的了。

不过，很感谢你的问题，我也是在逐题推敲，颇有同感。

154，(B) crash but also ignored demands by the pilots union that the investigation be expedited
我也考虑过这点，但后来发现如果如你所说，把句子改为“更合理”的顺序是：crash but also ignored demands that the investigation be expedited by the pilots union，问题更大了，成了expedited by the pilots union，所以，我以为ETS是为了避免更大的歧义而不得不“退而求其次”的。

174，这题我到觉得believed .....仅仅是插入语，歧义的可能存在，但不致命，而且该选项是5个里面最好的。其实，在推敲的过程中，会遇到不止一个二个这样的例子，尤其在GEMJ和SBBI以前的讨论帖里，这类问题是常客。所以，我觉得还是那个原则：平时严格要求，按优先次序来做改错题，形成对题目错误选项的敏感性；考场上利用优先级，排除明显歧义，同时用各种合理的方法比较出最好的答案----不是最正确的，但是是该5个选项里最好的。

不知我的回答你满意了没。

b错在哪里呢？
只是因为不够简洁吗？
