求助GWD 31-18

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

偶选B, 觉得是同时省略了could be, 网上也有人选C, 劳烦NN们出来给指正一下, 谢谢!

right

我也选B，C的and it could reduce its crime rate和前面的被动不对称。

B:  the city’s streets could be cleaner, its fire code better enforced, and its crime rate reduced if...同时省略could be 吧。。。

同意B

B is not correct, because the Be can not be ignored, only "Could "can be omitted.
