Most respondents to a magazine survey who had recently listened to a taped reading of a certain best-selling novel said that they had enjoyed the novel, while most respondents who had recently read the novel themselves said they had not enjoyed it. These survey results support the contention that a person who listens to a taped reading of a novel is more likely to enjoy the novel than a person who reads it is. Which one of the following, if true, would most weaken the argument? ['Most people can read a novel in considerably less time than it would take them to listen to a taped reading of it.', 'Most of the respondents who had listened to a taped reading of the novel had never read it, and most of the respondents who had read the novel had never listened to a taped reading of it.', 'The novel in question, unlike most novels, included dialogue in many different dialects that are more understandable when heard than when read.', 'When people are asked their opinion of a best- selling novel that they have read or listened to on tape, they are more likely to say that they enjoyed the novel than that they did not enjoy it.']
