单选题
Only Germany, with incentives to business to encourage the employment of older people, and France, with the introduction of legislation making it illegal to use age barriers in recruitment—______to make employees redundant because of their age—______done anything substantive to combat age discrimination.
【正确答案】
B
【答案解析】解析：句意是，德国鼓励老年人就业，法国讲到雇用老年人是不合法的——或者可以说，由于他们年龄大导致雇员多余——这两个国家已经采取实际行动辩论年龄歧视问题。本句主语是Only Germany and France，所以要用have，破折号之间的内容是对前面一句的解释，所以用as，表示或者可以说，所以正确答案为B。
