Answer: Only (1) and (4)
(1) The boy moves away with the higher speed:
According to Newton’s third law, the force exerted by the man on the boy and the force exerted by the boy on the man are an action–reaction pair, and so they must be equal in magnitude.
Therefore, the boy, having the smaller mass, experiences the greater acceleration.
Both individuals accelerate for the same amount of time, but the greater acceleration of the boy over this time interval results in his moving away from the interaction with the higher speed.
(4) The boy moves farther than the man in the same time interval
Because the boy has the greater acceleration and, therefore, the greater average velocity, he moves farther during the time interval in which the hands are in contact.
