Which of the following is an example of an opinion?

• A. The weather for a picnic is sunny and warm
• B. Water boils at 100°C at sea level
• C. The Earth revolves around the Sun
• D. Gold is a metal

Answer: (A)

Understanding the difference between an opinion and a fact. An opinion expresses a personal judgment or feeling and can vary from person to person, while a fact can be proven or measured and stays the same regardless of who describes it. The statement about the weather for a picnic being sunny and warm expresses how someone feels about the day for that picnic and could be different for someone else or in another situation. That is an opinion. The other statements are facts: water boils at 100°C at sea level is a standard scientific fact you can verify; the Earth revolves around the Sun is a well-supported astronomical fact; gold is a metal is a definitional fact about what gold is. So the weather description is the best example of an opinion because it reflects a personal view rather than something verifiable and objective.
