premise: A group of individuals are walking on a busy sidewalk with a river or lake in the view.
hypothesis: People are traveling in a city.
explanation_1: We don't know that the individuals who are walking are traveling.  They might live in the area where the busy sidewalk is located.   We are not told if that area is a "city" or a smaller town, village, whatever.
