Explanation:

Bias refers to a tendency to believe that some people, ideas, etc., are better than others. The phrase "messy and complex" in the sentence "International espionage—or spying—is a messy and complex business that has been around for as long as there have been governments (about five thousand years)." shows the author's personal view and judgment, which is a form of bias. The other options are more factual statements.

Answer:

"International espionage—or spying—is a messy and complex business that has been around for as long as there have been governments (about five thousand years)." (paragraph 4)
