The Orange Corporation is conducting market research in preparation for the launch of its new device, the 3-D eSlate. Thus far, in Orange's market research, two groups have emerged as likely buyers of the eSlate: medical professionals and people making more than $250,000 a year. Since the number of medical professionals in the target market plus the number of people making more than $250,000 a year in the target market is over 20 million people, Orange projects that if one-fourth of people in these target markets buy the eSlate, Orange will sell over 5 million units of the eSlate.

Which of the following, if true, would most weaken the author's conclusion?

(A) In surveys, less than 5% of medical professionals in the target market said they would buy the eSlate.
(B) The eSlate has many more uses for education professionals than for medical professionals.
(C) Previous projections from the Orange Corporation have generally been too optimistic.
(D) Many medical professionals make more than $250,000 a year.
(E) People who make more than $250,000 a year buy more electronic devices than people who make less than $250,000 a year
