Los Angeles has a higher number of family dwellings per capita than any large city. (A) a higher number of family dwellings per capita than any large city (B) higher numbers of family dwellings per capita than any other large city (C) a higher number of family dwellings per capita than does any other large city (D) higher numbers of family dwellings per capita than do other large cities (E) a high per capita number of family dwellings, more than does any other large city
问题是:numbers of 和 a number of 一样吗?也就是说如果B中than后加上do,是否也对?
