Question

In semantics, what does 'entailment' refer to?

• A. A relationship where one statement necessitates the truth of another
• B. A contradiction between two statements
• C. An ambiguous statement with multiple interpretations
• D. A statement that is always false

Answer 1

Answer:

A. A relationship where one statement necessitates the truth of another

Entailment occurs when the truth of one statement guarantees the truth of another. For example, 'John is a bachelor' entails 'John is unmarried.' This relationship is fundamental in logical semantics and helps to define the logical structure of language.
