11. Every week, the programming office at an FM radio station reviewed unsolicited letters from listeners who were expressing comments on the station’s programs,. One week, the station received 50 letters with favorable comments about the station’s news reporting and music selection and 10 letters with unfavorable comments on the station’s new movie review segment of the evening program. Faced with this information, the programming director assumed that if some listeners died not like the movie review segment, then there must be other listeners who did like it. Therefore, he decided to continue the movie review segment of the evening program.

Which on e of the following identifies a problem with the programming director’s decision process?

(A) He failed to recognize that people are more likely to write letters of criticism than of praise.

(B) He could not properly infer from the fact that some listeners did not like the movie review segment that some others did.

(C) He failed to take into consideration the discrepancy in numbers between favorable and unfavorable letters received.

(D) He failed to take into account the relation existing between the movie review segment and the news.

(E) He did not wait until he received at least 50 letters with unfavorable comments about the movie review segment before making his decision.
