A Heavy Seesaw Is Out of Balance

A heavy seesaw is out of balance. A lightweight girl sits on the end that is tilted downward, and a heavy boy sits on the other side so that the seesaw now balances.

A) The side the boy is sitting on will now tilt downward.
B) Nothing, the seesaw will still be balanced.
C) The side the girl is sitting on will once again tilt downward.
D) It is impossible to say without knowing the masses of the children.
E) It is impossible to say without knowing the values of the original distances.
