It can be inferred from the text that public service______.
A．have benefited many people
B．are the focus of public attention
C．are an inappropriate subject for humor
D．have often been the laughing stock请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：D
解析：细节推断题。第三段最后一句You will be on safer ground if youstick to scapegoats like the Post Office or the telephone system指出，如果你把邮局或电话局当替罪羊来开涮的话，你不会得罪人。由此推知，邮局和电话系统这些公共服务业是大众的笑柄(laughing stock)。所以D项正确。
