Employment costs rose 2.8 percent in the 12 months that ended in September, slightly less than they did in the year that ended in the previous quarter.

A.less than they did

B.less than it did

C.less than they were

D.lower than

E.lower than they were
  给的答案是A，可是语法笔记上不是说they,it在比较句中有指代错误的嫌疑吗？谢谢指教！还有用rise的时候是不是一定要用less？

前半句中只有一个简单的结构，没有从句，因此they在指代的时候不会造成混淆。
由于“比较”是“平行”结构的一种，此题其实是考查“平行中结构一致”，“主谓一致”两个点。

只有一个主语，楼主可能说是两个不同主语的比较 有指代错误吧。

对，我是这个意思，因为比较句中好像要用that, those 等
