premise: A ski jumper is in the air.
hypothesis: there is a jumper in the air
explanation_1: If the man is a ski jumper, then he is a jumper. This is a poor example.
premise_logic: exists p1 x1 x2 x3.(n_air(x3) & in(x1,x3) & n_jumper(x1) & of(x1,x2) & n_ski(x2))
hypothesis_logic: exists p1 x1 x3.(n_air(x3) & exists x2.((x1 = x2) & in(x2,x3) & n_jumper(x2)))
premise_sim: exists x1 x2 x3.(of(x1,x2) & n_ski(x2) & n_jumper(x1) & n_air(x3) & in(x1,x3))
hypothesis_sim: exists x1 x3.(n_air(x3) & exists x2.(n_jumper(x2) & in(x2,x3) & (x1 = x2)))
