Answer to Question 1

ANS: D
Cognitive thinking culminates in the capacity for abstract thinking. This stage, the period of formal operations, is Piaget's fourth and last stage. Concrete operations usually occur between ages 7 and 11 years. Conventional and postconventional thought refers to Kohlberg's stages of moral development.

Answer to Question 2

ANS: C
Testicular enlargement is the first change that signals puberty in boys; it usually occurs between the ages of 9 1/2 and 14 years during Tanner stage 2. Voice change occurs between Tanner stages 3 and 4. Fine pubic hair may occur at the base of the penis; darker hair occurs during Tanner stage 3. The penis enlarges during Tanner stage 3.
