What does the term "logical equivalence" mean?

Logical equivalence refers to a situation where two statements or arguments hold the same truth value in every possible scenario. This means that no matter what circumstances are considered, if one statement is true, the other is also true, and similarly, if one is false, the other is false as well. This concept is crucial in logic and reasoning, as it allows for the substitution of one equivalent statement for another without affecting the validity of an argument.

The definition aligns precisely with answer choice B, highlighting the uniformity in truth values across different situations. This principle is often used in logical proofs and analyses, aiding in determining the consistency and validity of arguments.

Understanding logical equivalence helps assess the relationships between various statements or propositions, which is vital for analyzing arguments effectively in logical reasoning.
