advocates想普及state law, 目的是加强禁烟.然而对大部地区cities and towns 的居民,他们已经有了local law,并且比state law 更严厉.所以普及state law 对他们来说,相当于禁烟不那么严格了,与advocates 的初衷背道而驰, 从而产生了circulating misleading.
主要是不明白它到底问的是什么: if so, the problem is reading. Do more reading and come back, you will see the difference: you can quickly narrow the answers to either B or C. At that point, use the CR techique, hopefully you can get the right answer.
