premise: Some young children are inside playing.
hypothesis: the children are siblings
explanation_1: can't infer they are siblings
premise_logic: exists p1 s1 x1.(exists s2 x2.((x1 = x2) & n_playing(x2) & a_inside(s2) & Theme(s2,x2)) & n_child(x1) & a_young(s1) & Theme(s1,x1))
hypothesis_logic: exists p1 x1.(n_child(x1) & exists x2.((x1 = x2) & n_sibling(x2)))
premise_sim: exists s1 x1.(n_child(x1) & exists s2 x2.(n_playing(x2) & a_inside(s2) & Theme(s2,x2) & (x1 = x2)) & a_young(s1) & Theme(s1,x1))
hypothesis_sim: exists x1.(n_child(x1) & exists x2.(n_sibling(x2) & (x1 = x2)))
