Recall that Howard Leventhal and his colleagues (Leventhal,Watts,& Pagano,1967) showed some smokers a graphic film about lung cancer and gave them a pamphlet with instructions on how to quit; other smokers received either the pamphlet alone,or watched the grisly film.After three months,those smokers who received only the pamphlet with instructions were smoking significantly more than those who both saw the film and received the pamphlet.Why?

A) Information alone is not sufficient if people are not motivated to use it.
B) Fear alone is not sufficient if people don't know how to reduce it.
C) A message must be relevant to people if they are to pay attention to it.
D) Fear,like other negative moods,encourages people to pay attention to the message.
