=> Flies(x, y)] =>
[ay Flies(y, x))
Which one the following is NOT a clause in the corresponding CNF formula? (f(.) and g(.) are Skolem
functions)
Hint: Use standardization-apart first, then Skolemization, and then CNF transformation.
OFlies(x, f(x) OR Flies(g(x), x)
O Living(f(x)) OR Flies(g(y), y)
O None of the mentioned
O Living(f(x)) OR Flies(g(x), x)
