598. Advertising by mail has become much less effective, with fewer consumers responding. Because consumers are increasingly overwhelmed by the sheer amount of junk mail they receive, most discard almost all offers without considering them. Thus, an effective way for corporations to improve response rates would be to more carefully target the individuals to whom they mail advertising, thereby cutting down on the amount of junk mail each consumer receives.
Which of the following, if true, would most support this recommendation? A There are cost-effective means by which corporations that currently advertise by mail could improve response rates. B Many successful corporations are already carefully targeting the individuals to whom they mail advertising. C Any consumer who, immediately after receiving an advertisement by mail, merely glances at it is very likely to discard it. D Improvements in the quality of the advertising materials used in mail that is carefully targeted to individuals can improve the response rate for such mail. E Response rates to carefully targeted advertisements by mail are considerably higher, on average, than response rates to most other forms of advertising. 看了OG关于B的解析:if many corporations already mail targeted advertising, and mail advertising is nonetheless yielding declining response rates, thay suggests that targeted mail is an ineffective way to increase response rates. 不是很明白是什么意思,求大佬分析一下
