premise: A group of people are walking down a sidewalk beside the beach.
hypothesis: The people plan to go tanning on the beach.
explanation_1: You can not infer they plan to go tanning.
explanation_2: Just because they are on the beach does not mean they are going to go tanning.
explanation_3: There is no mention of any plans or intentions the people have, or that they have an interest to go tanning. Just because they are walking by a beach doesn't imply they will do anything on the beach.
