D/E如何取舍？

GWD-10-Q24

For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries.

1. Britain, France, or Germany, with the unemployment rate having remained

2. have those of Britain, France, or Germany, and the unemployment rate remaining

3. have Britain, France, and Germany, and the unemployment rate has remained

4. the economy of Britain, France, and Germany, with the unemployment rate that has remained

5. the economies of Britain, France, and Germany, and the unemployment rate has remained

选E

D中the economy of  三个国家，应该是  economies

是三个国家分别的经济状况，所以是复数

那后面unemployment rate 也是三个国家的，为什么不用those of three

other countries?

前面是 三个国家并列起来用了and

后面是that of the other three countries，不一样

是 economy of Britain， economy of France or economy of Germany

就是说 economy用几次的意思

and 和 or 的区别
