单选题 The chief functions of direct-mail advertising are to familiarize prospective buyers with a product, its name, its maker, and its merits and with the product's local distributors.
【正确答案】 A
【答案解析】解析:本题中,prospective的意思是“预期的”。A项的potential“预期的”符合题意,如:Every seed is a potential plant.(每粒种子都可能长成植物。)其他三项responsive“响应的”,inquisitive“好奇的”, perceptive“有理解的”都不正确。
