prep1-11. (25071-!-item-!-188;#058&001704)

Japanese researchers are producing a series of robots that can identify human facial
expressions, to which they will then respond; their goal is primarily creating a robot that will
empathize with us.

(A) expressions, to which they will then respond; their goal is primarily creating
(B) expressions, then responding to them; primarily to create
(C) expressions and then respond to them; the researchers' primary goal is to create
(D) expressions as well as giving a response to them; their primary goal is creation of
(E) expressions and responding to them; primarily, the researchers' goal is creating  

正确项是C

prep的语法笔记中说：
(A)    第二个分句中的their在逻辑意思上应该指代researchers，与前面出现的代词they指代对象不一致; goal和creating概念不对等; primarily修饰creating,逻辑意思错误

“句子中一个代词重复出现，必须指同一对象。”

如果按这一规则，结合上面这句话，是不是将they和their视为同一代词？？？

“句子中一个代词重复出现，必须指同一对象。” 这一规则的准确用法是怎么样的？

求NN们指点

步骤是：一上来判断从句划线中发起者是robot can identify, 后面平行结构只能跟动词原型，去掉bde,只剩ac...明显c比a简洁，完事。。。想什么代词的事干嘛。。。

嗯，LZ根据简洁也是一种解法。

这里想弄清楚的是prep解释中说的代词用法。

不知道还有哪位大神可以解答。

我的理解是分号后是另一个主句，their与主句主语层级平行。第一个THEY是处于robots的限定从句中就近指代robots。
