Final answer:
The statement that 'Tautologies only entail other tautologies' is true because tautologies are always true and cannot lead to any conclusion that is not also universally true.
Step-by-step explanation:
The statement "Tautologies only entail other tautologies" is true. In logic, a tautology is a formula or assertion that is true in every possible interpretation, no matter the truth values of the individual components.
Therefore, a tautology cannot entail anything that is not also a tautology, as non-tautological statements have at least some interpretations where they are false.
A tautology will not entail a contradiction or a contingent statement since these can be false under some interpretations.
