The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.

Sometimes advertising is intentionally misleading. A few years ago, a brand of bread was offered to dieters (节食者) with the message that there were fewer calories (热量单位,卡路里) in every slice. It turned out that the bread was not dietetic (适合节食的), but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.

On the positive side, emotional appeals may respond to a consumer’s real concerns, considering fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.

Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.

The reason why the bread advertisement is misleading is that()

A. thin slices of bread could contain more calories

B. the loaf was cut into regular slices

C. the bread was not genuine bread

D. the total number of calories in the loaf remained the same

U、V、W、X、Y、Z分别代表六种短周期元素。X、U、V的原子序数依次增大1,U、V形成的单质是空气的主要成分,W的单质是密度最小的气体;Y与V位于同一主族,Z是轻金属之一。
合物UW4WXV3(以下称A)和UW4Z(YV4)2(以下称B),各自配成相等浓度的溶液。将B缓慢加入到A中,会生成白色沉淀D。将A缓慢加入到B中,开始无沉淀,继续加入,会生成白色沉淀E。
(1)称取0.260gD,用适量酸溶解完全后,加入0.1000mol/L EDTA二钠盐标准溶液50.00mL,用氨水调至pH=5.8左右,加入10mL pH=5.8的HAc—NaAc缓冲溶液,滴入1~2滴二甲酚橙指示剂,用0.08000mol/LZn2+标准溶液滴到红色,消耗20.84mLZn2+熔液。计算D的摩尔质量,写出D的化学式。
(2)称取0.463gE,按(1)法步骤进行,消耗Zn2+溶液也是20.84mL,计算E的摩尔质量,写出E的化学式。
