What characterizes an opinion?

An opinion is characterized by the fact that it cannot be proven true or false. Unlike factual statements, which can be verified through evidence or observation, opinions are subjective beliefs or interpretations that vary from person to person. They are influenced by individual experiences, feelings, and personal preferences, making them inherently unverifiable.

When considering the incorrect choices, the first option refers to statements that can indeed be verified and are objective in nature, thus distinguishing them from opinions. The second option discusses observable evidence, which relates to facts rather than subjective viewpoints. The third option pertains to quantifiable data, often used in empirical research or statistical analysis, which also contrasts with the notion of personal belief or opinion. Overall, the defining feature of an opinion is its lack of proof or universal agreement, aligning perfectly with the correct choice.
