This document discusses the differences between facts and opinions. Facts are statements that can be proven true or false, often with evidence, numbers or dates. Opinions are statements of personal beliefs that cannot be proven, and typically include words like "think", "feel", or "believe". To identify facts, one can check if a statement can be proven true; to identify opinions, one looks for words indicating personal perspective. Facts are used to support opinions, but opinions themselves are not provable statements.
