18: According to a recent survey of municipal services, the city’s streets could be cleaner, its fire code be better enforced, and its crime rate reduced if the current administration improved its management practices.

A: be better enforced, and its crime rate reduced

B: better enforced, and its crime rate reduced

C: could be better enforced, and it could reduce its crime rate

D: better enforced, and its crime rate could reduce

E: could be better enforced, and its crime rate reduce

很多人都选得B，我一开始也选得B，但是想了想，觉得可能and its crime rate可以和前面的the city's strees 平行啊。这样想对吗？快考试了很着急。xdjm们帮帮我吧。d还有什么错误吗？

可是好像fire code不能自己enforce，cirme rate也不能自己reduce。那么后面要么就是独立主格结构啦。两个独立主格和前面并列？？
