XDF的语法规则其实都不是一定的，我做这个题时也很困惑
后来把其他答案都排除了
没有other的都去掉，their也不好就只能选C
回头一看C是n+that+be+adj的结构，据说也是必错的，所以我觉得XDF的规则还是不要太钻

不过我真的好想选D，希望有更科学的解释

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 thanthose 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

我来回答一下为什么D和E错吧
这种结构more既可以修饰fuel-efficent又可以修饰cars，所以很模糊不能用。
XDF是说those不能单独出现，但是有特例就是比较的时候可以单独用(只能用）that或者those.

A now today重复
B their 指代不清
DE都是那个More的问题

但是其实我觉得C也有问题的
Those 指代不会不清楚么？谁能告诉一下？

首先这个those 是泛指， 如果用they 指代的是前面说的那些车，逻辑含义错误。
D中 their指代有歧义。

those 代词，意为：那些，那些的。可以代上文提到过的特指“同名异物”的复数名词，某种意义上说，可以是that的复数形式。不过要想代上文没有特指的复数名词，要用ones~
those who 形式的定语从句很常见的。比如这个
pp题

their primary careers reported high marital satisfaction, more than when retiring completely.

(A) more than when retiring
(B) more than if they were to retire
(C) more so than those who retired
(D) which was more so than those retiring
(E) which was more than if they had retired
答案为c
