Fact and opinion

Some writers don't always convey their message directly. This makes readers difficult to figure out what they  are really trying to say. It is moreover also difficult for the readers to distinguish between fact and opinion. Because these two may appear close together, even in the same sentence, readers need to carefully or even meticulously identify them. 

To make it easy, the key difference between facts and opinions is that facts can be verified, or checked for accuracy. While, opinions cannot be checked for accuracy. Opinions are what someone personally thinks or feels about an issue

Facts are objective. They can be found in official and legal records, and in the physical sciences. Objective facts are what researchers seek in laboratories or through controlled studies. Facts usually contains precise numbers. 

Opinions are based on subjective judgment and personal values. An opinion is a result of thinking that involves abstract concepts and different moral basic. We may find experts who have studied the same issue carefully and provide very different opinions in the end. That's why opinions are often disputed.

Although opinions cannot be verified for accuracy, writers should back their opinions with evidence, facts, and reason to support them and convinces the reader that it is a valid opinion. A valid opinion is one which is solid and persuasive, and one in which the writer cites other respected authorities who are in agreement.

Some opinions obviously deserve more attention than others do. When experts discuss something related to their field, their opinions are more informed and therefore more reliable than the opinions of people who know little about it.

Be an alert and critical reader. Understand the differences between facts and opinions. Interpret and apply both into your critical thinking.
