One hundred people listened to a single musical composition, “Study I,” on a certain morning. Later that day, they listened to “Study I” again and to another musical composition, “Study II,” and were asked which they preferred. A substantial majority preferred “Study I.” These results support the hypotheses that people prefer music they have heard on an earlier occasion to music they are hearing for the first time.
Which one of the following, if true, most strengthens the argument?
(A) Half of the members of a large group of people who heard only “Study II” in the morning and heard both “Study I” and “Study II” later the same day preferred “Study I.”
(B) Ninety percent of the members of a large group of people who listened to “Study I” and “Study II” without having heard either of the compositions on any earlier occasion preferred “Study I.”
(C) The group of 100 people who listened to “Study I” in the morning and to both “Study I” and “Study II” later the same day included some professional music critics.
(D) Of 80 people who heard only “Study II” in the morning and heard both “Study I” and “Study II” later the same day, 70 preferred “Study II.”
(E) Many of the 100 people who in the morning listened only to “Study I” complained afterward that they had not been able to hear well from where they had been seated.
