One of the signs of bulimia is: a. the inability to concentrate. b. isolation from family and friends. c. tearful, uptight, overly sensitive emotions. d. the ability to eat enormous meals without weight gain.

out of the choices i'd say d the ability to set goals, mainly because to desire to continue you need motivation but it isn't motivation in that part, but setting goals means you have an endgame and you want to reach it which sums up motivation.
