True or False: The negation of a tautology is a contradiction
1
True.
A tautology is a statement that is always true, no matter the truth values of its component propositions. Therefore, the negation of a tautology would be a statement that is always false.
On the other hand, a contradiction is a statement that is always false, no matter the truth values of its component propositions. Since the negation of a tautology is always false, it fits the definition of a contradiction.
