Question 2
An aunt is worried when she sees that her brother's sons are often tumbling on the ground and fighting playfully.

She expressed her concerns to her brother, who says, "They are just being boys, it's nothing to worry about." Which one of the following statements is most accurate?
◦ The aunt should not be too worried if the boys are having fun; rough and tumble play is typical across many cultures and does not lead to adverse outcomes.
◦ The aunt is right to be concerned because rough and tumble play often leads to higher levels of aggression in the long run.
◦ The aunt is right to be concerned because rough and tumble play almost invariably leads to injury in the long run.
◦ The aunt is right to be concerned because rough and tumble play can lead to deficiencies in motor ability or the delayed development of gross motor skills.
