premise: A person on a bicycle wears a helmet and jumps, soaring over the ground in front of a skyline and lake.
hypothesis: A person doing tricks on a bike to impress their friends.
explanation_1: Jumping and soaring does not necessarily imply he is doing tricks.  It is also not assumed that there are friends present or that they are trying to impress their friends.
explanation_2: Just because a person on a bicycle wears a helmet and jumps, soaring over the ground in front of a skyline and lake does not mean they are doing tricks to impress their friends.
explanation_3: Not everyone does tricks to impress friends.
