Curator: A magazine recently ran a very misleading story on the reaction of local residents to our controversial art exhibit. They quoted the responses of three residents, all of whom expressed a sense of moral outrage. These quotations were intended to suggest that most local residents oppose the exhibit; the story failed to mention, however, the fact that the three residents are all close friends. Which one of the following principles most helps to justify the curator's argumentation? ['It is misleading to present the opinions of people with no special expertise on a subject as though they were experts.', 'It is misleading to present the opinions of a few people as evidence of what the majority thinks unless the opinions they express are widely held.', 'It is misleading to present the opinions of a potentially nonrepresentative sample of people as if they represent public opinion.', 'It is misleading to present the opinions of people on only one side of an issue when the population is likely to be evenly divided on that issue.']
