GWD3-Q30:

Today’s technology allows manufacturers to make small cars more fuel-efficient now than at any time in their production history.

A.small cars more fuel-efficient now than at any time in their

B.small cars that are more fuel-efficient than they were at any time in their

C.small cars that are more fuel-efficient than those at any other time in

D.more fuel-efficient small cars than those at any other time in their

E.more fuel-efficient small cars now than at any time in



选C，解释说AB的their都有指代不清的嫌疑，那C选项的those没有嘛？those可以指代cars 也可以指代manufacturers啊

比较的主体是small cars，those就是指带cars，不能指带其他~

我觉得吧，首先D和E可以排除因为句子的意思是现在能做出小车子（减能源的），意思是因为车小所以减能源，而过去没有小车子，关于those我的理解是因为车子是被做出来的，所以是宾语。like manufacturer make small cars。 所以B里面的they是不合适的。
个人愚见，其实我也不懂those的用法。求牛人解释！
