premise: A group of individuals are walking on a busy sidewalk with a river or lake in the view.
hypothesis: The people in the picture are jogging as a group.
explanation_1: The individuals were walking, not jogging.  There is no mention of them posing for any picture.  Although they are called a "group of individuals" that seems to say that they're not participating in a group activity but rather walking on their own, as individuals.
