Answer to Question 2
B
Play becomes manipulative as the child learns control of the hands. Adults facilitate infant learning by planning activities that promote the development of milestones, and by providing toys that are safe for the infant to explore with the mouth and manipulate with the hands, such as rattles, wooden blocks, plastic stacking rings, squeezable stuffed animals, and busy boxes. Preschoolers demonstrate their ability to think more complexly by classifying objects according to size or color, making the cards more appropriate for them. Neither group is ready for paperback books. The sock puppet with movable eyes could create a choking hazard if one of the eyes comes off.
