Yet, in an effort to obtain valid information, she did not reveal that Florida's Bureau of Tourism was sponsoring her research; she asked participants in the interviews to give opinions on and express preferences among many places for vacationing, a technique that yielded as much information on Europe and California as on Florida.

    (A) were from a variety of backgrounds and hence had a variety of opinions about vacationing
    (B) had attitudes toward Florida that were more easily predicted than were their opinions on other places for vacationing
    (C) would tend to express favorable opinions when they thought such responses would please the sponsor of the research
    (D) would speak honestly about places for vacationing only during direct questioning
    (E) were more knowledgeable and candid about Europe and California than about Florida
