Answer:

HT Realm was right in saying that the child moves upward in the first two questions and downward in the third question. Simply translate them to the terminology provided in your given scenario and say that:

A) COUNTERCLOCKWISE

285 N*m > 235.2 N*m which means the teeter-totter rotates counterclockwise

B) COUNTERCLOCKWISE

237.5 N*m > 235.2 N*m which means the teeter-totter rotates counterclockwise

C) CLOCKWISE

190 N*m < 235.2 N*m which means the teeter-totter rotates clockwise
