The kid is on a float in the snow.
A kid is on a float outside.
Because there is snow, this implies that the kid is outside.
exists p1 x1 x3.(n_snow(x3) & n_kid(x1) & exists x2.(on(x1,x2) & in(x2,x3) & n_float(x2)))
exists p1 x1.(exists x2 x3.(on(x1,x2) & n_outside(x2) & of(x2,x3) & n_float(x3)) & n_kid(x1))
