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(B)
(E) with a history of high blood pressure running in their family
答案为什么是B? whose ---修饰pressure?
我觉得应在whose 前加个and. 请大家帮忙解释一下。
我选的是A。
A/C都错,构成run-ON错误: sht...have...are; B的whose跳跃修饰,不会产生歧异;

当初考tofel最关注run-on问题,现在做gmat sc貌似run-on问题被忽视了好多次。。。。。
