Faden: Most of our exercise machines are still in use after one year. A recent survey of our customers shows this. Greenwall: But many of those customers could easily be lying because they are too embarrassed to admit that they don' t exercise anymore. Faden: You have no way of showing that customers were lying. Your objection is absurd. Which one of the following most accurately describes a flaw in the reasoning above?

D: Greenwall presumes, without giving justification, that most people are dishonest about their personal habits.
