3.Advertisement is mainly paid for by _____.
答案：A) the customer

We might ask whether the cost of advertisement is paid for by the producer or by the customer.Since advertisement forms part of the cost of production（广告构成产品的部分价格）,which has to be covered by the selling price（不得不把售价包括在内）,it is clear that it is the customer who pays for advertisement（显而易见消费者为广告付费）.However,if large scale advertisement leads to increased demand（大型广告导致购买需求增加）,production costs are reduced（降低产品价格）,and the customer pays less（消费者就少付一些费用）.

分析：本题考查对后面句子段落的理解.
It is difficult to measure exactly the influence of advertisement on sales.When the market is growing,advertisement helps to increase demand（旺销市场有助于促进需求）.When the market is shrinking（市场收缩）,advertisement may prevent a bigger fall in sales than would occur without its support（做广告可以比没有广告的支持阻止更大的销售跌落）.
5.From the last sentence of this passage we conclude that _____.
答案：B) businessmen know well that advertisement could bring them more profits

最后一句 What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them 是个虚拟语气,如果商家确信不了广告的价值,他们就不会付出大价钱去做广告,言外之意指的是他们十分了解广告会给他们带来更多的利润.
