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?

【选项】Response rates to carefully targeted advertisements by mail are considerably higher, on average, than response rates to most other forms of advertising.
