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.

(A) and their families have a history of high blood pressure

(B) whose families have a history of high blood pressure

(C) and a history of high blood pressure runs in the family

(D) whose families have a history of high blood pressure running in them(E) with a history of high blood pressure running in their family

答案 B

想请问下为什么E不对

heslaw

把E带入，这个句子就变成了，people with... with....这个用词重复累赘，不合语法

这里需要一个从句来修饰young people

剩下B,D

in D, history of... running in them,

首先，them 指代不明，是family or the young people?

其次，这个表达方式错误，而且累赘, have a histroy of high BP, 足够说明问题
