Companies that advertise on television complain that digital television recording (DTR) services make it possible for consumers to watch television programs without viewing the commercials that these advertisers have paid the television networks to broadcast. The DTR service providers respond that their services may actually help the advertisers, because without their service, many consumers would not have been able to watch the programs--or the commercials in them--in the first place.
Which of the following, if true, offers the most support to the advertisers’ claims that the DTR services are currently hurting their businesses ？（）
A. Even the best commercials are usually less entertaining than the programs that consumers choose to watch for themselves.
B. DTR services charge such high rates that only a small percentage of consumers subscribe to them.
C. The average per-second cost of advertising on television has risen every year for the past two decades.
D. More than 90 percent of subscribers to DTR services opt to use a setting that automatically edits out commercials.
E. DTR services alter the television viewing experience by allowing customers to view the program of their choice at the time of their choosing.
参考答案：D
解析：
Answer D suggests that the defense stated by the DTR services providers works only in theory, not in practice. If most subscribers to these services are automatically avoiding all commercials, the companies that have paid to broadcast advertising messages to these viewers are going to get less of a return from their advertising investment, which will hurt their businesses.
