Historians examine sources for credibility or truthfulness. This is because each source reflects a point of view, or a general attitude about people and life. Sometimes point of view is expressed as bias, or an unreasoned, emotional judgment about people and events. 3 Cause and Effect A cause is what makes an event happen. The event that happens as a result of the cause is known as the effect. 4 Fact and Opinion A fact answers a specific question such as: When and where did it happen? Statements of fact can be checked for accuracy and can be proven. An opinion expresses beliefs, feelings, and judgments. It can not be proven. Look for clues such as: I think, probably, it seems to me. 5 Fact or Opinion? 1. The Han dynasty ruled China from 202 B.C. to A.D. 220. 2.
