premise: A woman dressed in black is silhouetted against a cloud darkened sky. hypothesis: A woman in black stands outside at night waiting for a train.
neutral: One does not necessarily have to be outside to cast a silhouette against a cloud darkened sky. For example, someone can stand in front of a large picture window. A cloud darkened sky can occur during overcast conditions during the daytime. This woman may not necessarily have been waiting on a train.
