1. 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）
我想问c 解释说划线部分是完整句子，句子和名词短语 young people形式不对称，不能并列。
c中的 a history of high blood pressure runs in the family不能和higher-than-average blood pressure并列，一起修饰young people吗？
问了一下，C中首先in the family用了定冠词the，但前面并没有提到什么family所以有错。其次，如果是a history of high blood pressure runs in the family和higher-than-average blood pressure并列, runs算什么成分？应该改为running 或者that runs
