Which of the following, if true, strengthens the argument for shifting to television infomercials?

A) Many mainstream companies such as P&G, Dell, Disney, and Bose have begun using infomercials to sell their wares.
B) ValueNet could slightly modify its telemarketing techniques and receive a much better customer response.
C) TV media production costs are expected to increase substantially as the economy moves toward recovery.
D) The majority of Americans have registered their telephone numbers with the National Do Not Call Registry, and the number of registered numbers continues to grow.
E) Despite objections and angry responses to cold calls, total sales from telephone marketing have been steady over the years.

Answer: D
Explanation: D) ValueNet would want to move from using outbound telemarketing if it's no longer an effective way to reach the target market. Choice D indicates that a substantial portion of ValueNet's market has registered with the Do Not Call Registry, meaning that ValueNet cannot legally make unsolicited outbound calls to those individuals. With its market access shrinking, ValueNet needs to come up with a new plan. Choice A describes the actions of other companies but doesn't indicate whether a similar strategy would be effective for ValueNet and its products. Choice B, if anything, weakens the argument for moving away from an established telemarketing system. Choice C makes the proposition unattractive, indicating that ValueNet would have to make a substantial investment in creating infomercial spots. Choice E calls for using the current strategy despite its drawbacks.
