Read the passage:

James is trying to learn more about the countrys role in a chemical spill that occurred a few miles from his farm. He's surprised to find only a very short article in the local newspaper. When he wonders why, he suddenly remembers that the editor of the newspaper and the head of the county council are cousins.

Which method of identifying bias is most clearly used in the passage?
