premise: A group of people are posing as though flung back by the shock wave of someone punching the ground.
hypothesis: Wild Bill Hickock wrote the Iliad.
explanation_1: A group of people is different than Wild Bill Hickrock who is one person. Posing as though flung back is different than wrote an Iliad.
explanation_2: Will Bill Hickock is a person and cannot be referred to as being a group of people. Writing the Iliad is not the same as posing.
explanation_3: Wild Bill Hickock is a single person, not a group of people.
