premise: The horses are in a straight line.
hypothesis: There are multiple horses.
explanation_1: if there are horses, this is a plural word and implies more than one, or multiple, horses.
premise_logic: exists p1 x1.(n_horse(x1) & exists s1 x2.(in(x1,x2) & n_line(x2) & a_straight(s1) & Theme(s1,x2)))
hypothesis_logic: exists p1 x1 s1 x2.((x1 = x2) & n_horse(x2) & a_multiple(s1) & Theme(s1,x2))
premise_sim: exists x1.(n_horse(x1) & exists s1 x2.(n_line(x2) & in(x1,x2) & a_straight(s1) & Theme(s1,x2)))
hypothesis_sim: exists x1 s1 x2.(n_horse(x2) & a_multiple(s1) & Theme(s1,x2) & (x1 = x2))
