Unlike emergency calls that travel through regular telephone lines, where they thus automatically inform the operator of the location and phone number of the caller, cellular calls require emergency operators to determine the location of the caller.

where只能指代具体的地点,telephone lines是抽象的地点
Unlike排除CDE
个人感觉这里要对比的是两种calls告知location的方式,一种是自动,一种是需要operator。
A选项将要强调的对比的核心变成了lines的修饰 所以应该选B
根据unlike如何排除CDE?
我的理解哈:unlike 在进行比较的时候和like是一样的 两个对比的对象应该是名词 结构也要严格平行 。这道题里就是Unlike emergency calls(that....), cellular calls... 对比两种calls。C里错误比较了the location ,DE是emergency operators

老师这道题中间用了thus 不应该是有因果关系要用从句么,为什么两句话并列了?
同觉得有因果关系
主句是说to determine the location of the caller 所以前半句也要说location 而不是location做修饰
个人觉得可能主要是定语从句里where的用法不对,在定从中where只能修饰地点名词,可能应该改为through which什么的更好。thus的话前面加and说regular calls是travel from电话线并因此能告知operator...没有硬伤。
