BIt is an erratic pattern
CIt is not an erratic pattern
DA uniform rise up to the middle teens and a gradual levelling off during the middle twenties ✓ Correct
Correct answer: (D) A uniform rise up to the middle teens and a gradual levelling off during the middle twenties — Mental growth is best explained as a uniform rise up to the middle teens and a gradual levelling off during the middle twenties, so that is the answer.
Explanation
★Mental growth is best explained as a uniform rise up to the middle teens and a gradual levelling off during the middle twenties, so that is the answer.
★Mental ability grows fairly steadily through childhood and into the middle teens.
★After that the rise slows and gradually levels off around the middle twenties.
★Saying it simply runs parallel to physical growth is too loose, since the two do not match exactly.
★Calling it an erratic pattern is wrong, as mental growth follows a fairly regular course.
★So the description of a uniform rise then a gradual levelling off is the most suitable.
