参考答案

正确答案：A
解析：总结题。主持人问嘉宾Simon人们讲礼貌需要做什么，而Simon的个人观点是许多的教条其实反映了人们所处的阶级：...the truth of it is that most of them are about class. 进而他有论述到不同的礼貌习惯有其人类学原因，其次他列举了英国不同阶层手握刀叉方式的不同来说明不同阶层的人有他们自己约定俗成的一套礼仪规范，即：...in Britain there are sort of two ways of holding a knife, very broadly. And broadly speaking the middle-classes hold it with the index finger on the top, gripped in the hand. And working-class people hold it like a pen. Entirely a class distinction and people mercilessly exploit it if they want to. 所以答案为A。
