A survey of a city' s concertgoers found that almost all of them were dissatisfied with the local concert hall. A large majority of them expressed a strong preference for wider seats and better acoustics. And, even though the survey respondents were told that the existing concert hall cannot feasibly be modified to provide these features, most of them opposed the idea of tearing down the existing structure and replacing it with a concert hall with wider seats and better acoustics. Which one of the following, if true, most helps to explain the apparent conflict in the concertgoers' views, as revealed by the survey? ['Many popular singers and musicians who currently do not hold concerts in the city would begin to hold concerts there if a new concert hall were built.', "The city's construction industry will receive more economic benefit from the construction of a new concert hall than from renovations to the existing concert hall.", 'A well-publicized plan is being considered by the city government that would convert the existing concert hall into a public auditorium and build a new concert hall nearby.', 'Before any of the survey questions were asked, the respondents were informed that the survey was sponsored by a group that advocates replacing the existing concert hall.']
