Final answer:
The passage illustrates a bias where the coach assumes the Swedish and French teams used illegal steroids without supporting evidence.
Step-by-step explanation:
The bias illustrated in the passage is that the coach is making a subjective claim without any factual evidence to support it. The coach assumes that the Swedish and French teams must have been using illegal steroids because they beat the U.S. team, disregarding the possibility that the opposing teams trained hard and were skilled. This demonstrates a bias towards putting blame on others rather than acknowledging the strengths of the opponents.
