Piaget believed that each child: a. progresses through a series of eight stages of psychosocial development. b. is biologically programmed to learn any language. c. actively tries to make sense of his or her environment. d. passively soaks up information about the world.

Piaget believes that each child actively tries to make sense of his or her environment.

Option C.

Explanation:

From the sensorimotor stage, to the pre-operational, followed by the concrete operational and formal operational, Piaget believes the growth and the evolving of the child is gradual, and the child tries actively (through different activities) to make sense/understand/comprehend his environment.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
