I think it would be a misplaced modifier.
the sentence should be "will drank nearly a gallon of lemonade."
A divorce can be very hard on a child, instead of learning you'll be thinking if you had any part in breaking your parents up or if not you then who fault was it? mom? dad? some out side force? an annoying sibling? a child has a hard time understanding the fact that it doesn't have to be anyone's fault and some times people drift apart.
