Politician: Most of those at the meeting were not persuaded by Kuyler' s argument, nor should they have been, for Kuyler' s argument implied that it would be improper to enter into a contract with the government; and yet -- as many people know -- Kuyler' s company has had numerous lucrative contracts with the government. Which one of the following describes a flaw in the politician's argument? ['It rejects an argument merely on the grounds that the arguer has not behaved in a way that is consistent with the argument.', 'It concludes that an argument is defective merely on the grounds that the argument has failed to persuade anyone of the truth of its conclusion.', 'It rejects an argument on the basis of an appeal to popular opinion.', 'It rejects a position merely on the grounds that an inadequate argument has been given for it.']
