While 65 percent of the eligible voters who were recently polled favor Perkins over Samuels in the coming election, the results of that poll are dubious because it was not based on a representative sample. Given that Perkins predominantly advocates the interests of the upper-middle class and that the survey was conducted at high-priced shopping malls, it is quite probable that Perkins' s supporters were overrepresented. Which one of the following statements most accurately expresses the main conclusion of the argument? ["The poll's results probably do not accurately represent the opinions of the voters in the coming election.", 'Samuels is quite likely to have a good chance of winning the coming election.', 'The poll was intentionally designed to favor Perkins over Samuels.', "Samuels's supporters believe that they were probably not adequately represented in the poll."]
