【解释】T-9-Q39. 987-675

这题答案是B，我选了C，以下是我的总结，其中D选项不知道解释的对不对

请大家指正

Studies show that young people with higher-than-average blood pressure
                    and their families have a history of high blood pressure are more likely than others to develop a severe form of the condition.

Whose跳过with+n介词短语结构修饰young people，介词短语不是句子主干，找主干的时候可以拿掉不看

如果是用and的话，那么young people是are的主语，with连接两个并列的修饰成分，一个是higher-than-average blood pressure，那么A/C中的另外一个修饰都是S+V的结构，不能和一个n对称，所以A/C错

A.      and their families have a history of high blood pressure  S+V结构不对称

B.       whose families have a history of high blood pressure

C.       ！and a history of high blood pressure runs in the family  S+V结构不对称

D.      whose families have a history of high blood pressure running in them  them指代people还是families不清楚

E.       with a history of high blood pressure running in their family  两个with结构没有and连接，错

我正在想这题，谢谢LZ

C的如何不对称？ a history 和runs 不是正好主谓一致吗？
