106. Marconi’s conception of the radio was as a substitute
for the telephone, a tool for private conversation;
instead, it is precisely the opposite, a tool for
communicating with a large, public audience.
(A) Marconi’s conception of the radio was as a
substitute for the telephone, a tool for private
conversation; instead, it is
(B) Marconi conceived of the radio as a substitute
for the telephone, a tool for private
conversation, but which is
(C) Marconi conceived of the radio as a tool for
private conversation that could substitute for the
telephone; instead, it has become
(D) Marconi conceived of the radio to be a tool for
private conversation, a substitute for the
telephone, which has become
(E) Marconi conceived of the radio to be a
substitute for the telephone, a tool for private
conversation, other than what it is,

题目选C，og说分号后面的it指的是radio ，可是为什么不会造成指代不清（指代telephone）呢？
是优先指代主语吗?可是分号后面是2个句子呀
而且，c里面的that是跟在conversation 后面的，这个that应该是跟在radio后面修饰radio啊~~tel的替代品是radio  不是conversation呀

我是这么做的：
这道题明显WHICH用法不对，排除B,D
E中的WHAT IT IS错，排除
剩下A和C
A中的STH IS AS STH错，排除A
就剩下C了

虽然LZ的问题我也是很纳闷，不过将自己的分析步骤晒出来，和大家共勉

LZ的问题等待牛牛们来解答~~~

从逻辑意思上来看是不会存在歧义的

前句：radio 是电话的代替。转折，其实radio是XXX

按逻辑的意思来说确实选c，但是有好多题都不按照逻辑的意思选的啊 比如这个
OG12  75
75. A proposal has been made to trim the horns from
rhinoceroses to discourage poachers; the question is
whether tourists will continue to visit game parks and
see rhinoceroses after their horns are trimmed.
(A) whether tourists will continue to visit game
parks and see rhinoceroses after their horns are
(B) whether tourists will continue to visit game
parks to see one once their horns are
(C) whether tourists will continue to visit game
parks to see rhinoceroses once the animals’
horns have been
(D) if tourists will continue to visit game parks and
see rhinoceroses once the animals’ horns are
(E) if tourists will continue to visit game parks to
see one after the animals’ horns have been



选C， A的错误OG解释说their 这个词ambiguous 但是按照逻辑的话their只能指rhinoceroses 不可能指游客或者公园呀~但OG得解释却没按逻辑的意思来~~
丹迪可不可以按逻辑来判断指代呢？

不赞同这么做，谁说了D的which用法不对？只是不好，如果没有C，D就是正确答案。用What it is和sth is as sth来排除也是会吃药的，这个是老师套路吧。GMAT经常出些所谓老师套路让你错的题。这些词只是小问题，不是大问题。


我的解题思路是：
首先B排除。很明显，but后面要么前后都是句子，要么前后有对应。这里but后面是which，前面没有which或类似词对应，所以严重错误，排除
A是语义不平衡。句子是说radio（本来）被认为是什么，但是不对，其实是什么。那么A是里面划线外事a tool for doing是对radio修饰的，而前面的对应部分a tool for private conversation是对telephone修饰的。所以不好，先排除
C，平衡，两个a tool for都是修饰radio，先放着
D，也是，平衡，两个a tool for都是修饰radio，先放着
E，和A一个毛病，排除


然后， C、D开比
就是你发现的which的问题，所以C比D好。“切忌注意，不要看到which用作非限定性定于从句就算错。虽然，非限定性的确有语义不清的问题，在大部分情况下可以用这点做题。但是如果碰到难题，没有语义清晰的选项，则它还是能成为正确选项的，毕竟非限定性定于从句没有语法问题。”

A的错误有两个，一个是这两个动作不是并列的，是有先有逻辑关系的，带有目的性。而且their是指代不清。C指代清楚了，所以C比A强，就选C。我们不研究每个题目到底算不算错或对，我们之研究以下哪个表达更优

解释的很清楚~但我有个问题：到底可不可以按照逻辑的意思来判断题目指代呢？如果按照逻辑意思的话，游客是不会有horns 更不会trimmed~但OG的解释还是说了their有可能只带游客，也就是说不能按照逻辑的意思来判断了？

gmat928

; instead, it
这种形式的it一般指代是没有问题的

另外一例

Pioneered by scientists at Los Alamos National Laboratory, BEAM robots are not programmed to walk; instead they use brain like circuits called neural networks to learn to walk through trial and error.

但是D中which的指代问题是大大的，which离他本应指代的radio太远了
