Christy Ross makes three observations about Ben's experiment. What are they?

Christy notes three concerns about her husband's experiement. First, she believes that the students enjoy having someone else directing them because they do not have to think. Second, she chides her husband the way he talks about his student. In the way he talks, he makes his class sound like they are superior to all others. Third, she tells her husband that he no longer helps around the house.... she chides him that he may just be becoming the guinea pig in his own experiment.
