请看讲解视频
A. 将small cars的now和at any time相比较，现在的小车和其他时候的该小车做比较，但应该将today's small cars和small cars at any other time做比较的。at any time并没有剔除掉Today的时间点。today和now重复
B. they指代的就是前面的small cars，还是将现在的该小车和其他时候的该小车做比较。at any time没有剔除掉today的时间点。they是同物指代，指代的就是前面出现的东西
C. right，those是同类指代，指代的是同类的small cars。
D. more fuel-efficient small cars有歧义，到底是更多的省油车还是更省油的车？their可能指代manufacturers也可能指代small cars
E. more fuel-efficient small cars有歧义，到底是更多的省油车还是更省油的车？at any time没有剔除today的时间点
