premise: A dolphin above water
hypothesis: There is a dolphin.
explanation_1: The dolphin has a location; therefore, there must be a dolphin.
premise_logic: exists x1 x2.(a_topic(x1) & above(x1,x2) & n_water(x2) & n_dolphin(x1))
hypothesis_logic: exists p1 x1 x2.((x1 = x2) & n_dolphin(x2))
premise_sim: exists x1 x2.(n_water(x2) & n_dolphin(x1) & above(x1,x2) & a_topic(x1))
hypothesis_sim: exists x1 x2.(n_dolphin(x2) & (x1 = x2))
