Mr. Epstein is showing the class a picture of a tiger. Ally, one of his students, tells him that she has one of these animals at home. He tries to explain to her that she must have a cat, not a tiger. She insists that it is a tiger and that she got him at the pet store last month. According to Piaget, the teacher is trying to throw Ally into a state of:a. disequilibrium.
b. accommodation.
c. equilibration.
d. equilibrium.
