premise: Children participating at a party while looking at the one kid in exuberance over the new toy.
hypothesis: A child just opened his smallest gift at his party
explanation_1: Just because a kid is exuberant over the new toy doesn't mean he opened his smallest gift
explanation_2: The "new toy" is not mentioned to be small, especially not the smallest The kid is also not mentioned to be the one receiving gifts/whose party it is, so it could have been somebody else's gift, not his.
explanation_3: We don't know if the new toy is his smallest gift.
