"Nyah, nyah, nyah, nyah," Diane says to her younger sister Rhonda. "I have reached the formal-operational stage of thinking, so according to Piaget, I can now think ____ and you can't!" As ridiculous as this conversation is, if Diane is 13 and Rhonda is 9, what would the correct answer be?

According to Jean Piaget's theory of cognitive development, the formal operational stage begins at around age 12. At this stage, individuals are able to think abstractly and hypothetically. Since Diane is 13, she would be in the formal operational stage, allowing her to think hypothetically, unlike her younger sister Rhonda, who is 9 and likely in the concrete operational stage, where logical thinking is limited to concrete situations.
