Terrance is in high school and needs to take an advanced science course this year.He has chosen chemistry.His parents aren't surprised that chemistry is introduced to Terrance now because when children enter the ________,they are able to engage in abstract thinking,can consider hypothetical propositions,and can deduce consequences.

A) concrete operational stage
B) preoperational stage
C) formal operational stage
D) sensorimotor stage

The formal operational stage, which typically begins around age 12, is marked by the ability to engage in abstract thinking, consider hypothetical propositions, and deduce consequences. This makes it an appropriate time for Terrance to take on an advanced science course such as chemistry. The concrete operational stage (A) occurs from ages 7-12 and is marked by the ability to think logically about concrete things, while the preoperational stage (B) occurs from ages 2-7 and is marked by symbolic thinking and egocentrism. The sensorimotor stage (D) is the earliest stage of cognitive development, occurring from birth to age 2, and is marked by the use of sensory and motor skills to explore the world.
