premise: A man is working on steel.
hypothesis: The man is a construction worker.
explanation_1: Working on steel does not imply construction work, more likely it implies a steel mill worker.
premise_logic: exists e1 x1 x2.(on(e1,x2) & n_steel(x2) & Actor(e1,x1) & v_work(e1) & n_man(x1))
hypothesis_logic: exists p1 x1.(n_man(x1) & exists x2 x3.((x1 = x2) & n_worker(x2) & of(x2,x3) & n_construction(x3)))
premise_sim: exists e1 x1 x2.(v_work(e1) & on(e1,x2) & n_steel(x2) & n_man(x1) & Actor(e1,x1))
hypothesis_sim: exists x1.(n_man(x1) & exists x2 x3.(of(x2,x3) & n_worker(x2) & n_construction(x3) & (x1 = x2)))
