<u>A fact is something that can be proven true</u> and <u>an opinion is something that you think</u>, it <u>doesn't have to be right</u> and is <u>more of a preference</u>. In summary, fact is objective reality and opinion is a subjective statement.
FACT "Pringles aren't actually potato chips." OBJECTIVE REALITY - Pringles aren't made of sliced potatoes, they're made from dehydrated potato flakes pressed together to make a parabolic shape.
OPINION "George Crum's original potato chips were probably better than the ones made today." SUBJECTIVE REALITY - Whoever says this has probably never found a potato chip they liked, and doesn't know that he created them by accident, and they were probably burnt so they didn't taste as good.
Hope this helps. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day and Black History Month! :-)
