3) Your roommate, Serafina, a psychology major, said, "The problem with economics isthat it assumes that consumers and firms always make the correct decision. But we know that everyone's human, and we all make mistakes." Is Serafina's criticism accurate?

c. No. Economics assumes that economic agents behave rationally, meaning they make the best decisions given their knowledge of the costs and benefits of these decisions.
