单选题

A.Decide on what specific means of communication to employ.
B.Conduct a large-scale survey on customer needs.
C.Specify the objectives of the campaign in detail.
D.Pre-test alternative ads or commercials in certain regions.

参考答案D
解析:
What would advertising agencies often do before a national campaign?
D.。详解:四个选项均为动词原形开头的句子结构,可以判定本题考查的是行为动作,由B.选项中的survey和D.选项中的Pre.test,ads可以推测,本题考查内容与真正投放广告前的行为有关。短文最后提到,广告公司在向全国投放广告之前,通常会先小范围地在报纸、电视等渠道上进行测试,也就是说,他们会在特定的地区进行广告试验。
