Why Was the Original Person-Situation Debate Ill-Conceived

Why was the original person-situation debate ill-conceived?

A) It is unreasonable to assume that typical or usual personality tendencies will predict behavior perfectly across the vast variety of situations in which people find themselves.
B) Personality had not yet been established as an identifiable discipline in the 1960s; any outcomes based on personality measures were tentative at best.
C) Nature-versus-nurture is a much more important question to ask than whether it is the person or the situation that determines behavior.
D) The situations social psychologists investigated were usually mundane or trivial; high-impact situations were needed to reveal the true contributions of traits and the situation.
