问题 What is the one huge problem that we haven’t really solved? [br] There is no doubt that environmental regulation
选项 A、is cumbersome
B、produces an effect
C、varies wildly
D、needs to be streamlined
答案 B
解析 细节题。根据题干信息词environmental regulation定位到第五个小标题末句Some environmental regulation may be too cumbersome(麻烦的)and needs to be streamlined-standards can vary wildly between regions-but there isn’t any doubt that environmental regulation actually works，即：虽然有一些麻烦，但是环境规则还是有作用的，故选B。
