Which indicator would most strongly suggest bias in an informational text?

• A. The author uses balanced data from multiple sources
• B. The author provides a long bibliography
• C. The author presents selective facts that favor one side
• D. The author uses formal language

Answer: (C)

Detecting bias in informational texts comes from watching how evidence is presented. When an author consistently selects facts that support one side while leaving out opposing information, the text nudges readers toward a particular conclusion. That kind of selective presentation is the strongest signal of bias because it shapes what readers consider important and what conclusions they are led to draw.

Balancing data from multiple sources helps counter bias, because it shows a fuller range of evidence. Simply providing a long bibliography shows the author has done research, but it doesn’t by itself prove bias. Using formal language is about tone and style, not about whether the content presents information fairly.
