What is the difference between purge disorder and bulimia?

Bulimics typically eat a bunch (binge) and then throw up. Purge disorder is when you just throw up after eating a normal portioned meal.

b and d are your answers i just answered this question

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.
