单选题 Advertising sells its products by offering seductive promises of youth, beauty, health, money, ease, romance, better lifestyle, even time. There's no logical connection between a car and a cougar, but the image is powerful and presented with sophistication. We buy it and we may well buy the product.
When it comes to advertising, let the buyer beware. There are several less-than-candid techniques which advertisers use to get our attention. A product may be filmed or photographed in such a way to make it appear bigger, better, or more luscious. A product may be presented as being "unique", "one-of-a-kind", or "supreme", when in fact it's identical to other products on the market. A product may claim to be "new" or "improved" when only an insignificant change has been made.
Finally, an advertiser may offer distorted truths or even tell outright lies. It takes a while for the government or the competition to catch up with false claims in advertising. Meanwhile, the public has been led to believe that a mouth wash can cure the common cold, or that bee pollen retards aging in human skin.
The consumer's best defense is awareness. He can listen to, but not learn, the emotional message broadcast by the ad. He can distinguish between what the ad pretends to offer and what it is really selling. A face cream, for example, can only do so much. It can reduce dryness and provide temporary smoothness and moisture to the skin. But it is made in a factory, not in a magician's study. It cannot turn back the clock.

【正确答案】 C

【答案解析】根据文章第二段的内容，一些产品被照像机或摄像机拍后显得比实际更大，更好，更豪华了；一些产品被称为是独一无二的，最好的，但实际上和其他同类产品一模一样；还有一些产品被称为有了改进或突破，而实际上只是有了微不足道的变化，因此，作者认为许多广告是不可信的。
