premise: A woman is pulling a child on a sled in the snow.
hypothesis: A mother pulls a child on a sled during a fun day at Big Bear.
explanation_1: Just because the woman is pulling a child on a sled in the snow does not necessarily mean that she is the child's mother.  It does not necessarily mean that the child is having fun, that it is during the day nor where they are located, Big Bear or somewhere else.
explanation_2: The woman isn't necessarily the child's mother and snow doesn't imply fun day at Big Bear.
explanation_3: woman does not imply mother. Sledding does not have to be at Big Bear.
