Which helps distinguish fact from opinion in an argument?

• A. They are always opinions
• B. They are never supported
• C. Facts come from reliable sources
• D. Facts depend on mood

Answer: (C)

The main idea being tested is how to tell fact from opinion by looking at evidence and sources. A fact is a statement that can be proven or verified with evidence, while an opinion expresses a belief or judgment and reflects a person’s feelings.

Facts come from reliable sources because trustworthy sources provide evidence that others can check and verify. When a claim is supported by credible data, research, or expert testimony, it strengthens the case that the statement is a fact rather than a mere opinion. That makes this option the best because it directly points to evidence and trustworthiness as the way to distinguish facts from opinions.

The other statements don’t fit because they imply things that aren’t true: facts are not always opinions, facts can be supported by evidence, and facts do not depend on mood.
