premise: A rock climber ascends.
hypothesis: There is a person climbing while outside.
explanation_1: just because a rock climber ascends doesn't mean  a person is climbing while outside.
premise_logic: exists e1 x1 x2.(Actor(e1,x1) & v_ascend(e1) & n_climber(x1) & of(x1,x2) & n_rock(x2))
hypothesis_logic: exists p1 x1 e1 x2 x3 x4.((x1 = x2) & while(e1,x4) & n_outside(x4) & Actor(e1,x3) & v_climb(e1) & (x2 = x3) & n_person(x2))
premise_sim: exists e1 x1 x2.(v_ascend(e1) & of(x1,x2) & n_rock(x2) & n_climber(x1) & Actor(e1,x1))
hypothesis_sim: exists x1 e1 x2 x3 x4.(while(e1,x4) & v_climb(e1) & n_person(x2) & n_outside(x4) & Actor(e1,x3) & (x2 = x3) & (x1 = x2))
