Since you didn't include the statements in your question there is no way for us to know
A statement that is subjective, ambiguous, or based on opinion cannot be used to explain the steps of a proof. In a mathematical proof, each step must be based on objective facts, definitions, axioms, or previously proven theorems in order to ensure the validity and rigor of the argument. Statements that rely on personal beliefs, feelings, or interpretations are not suitable for constructing a logical proof.
The answer cannot be "a proof" since that can equally be used to show that a statement must be false.
