What is the central idea of the passage?

The law was not exactly fair in Europe during the Middle Ages. Back then, you could blame someone in your town for committing a crime. The “criminal” could then challenge you to a fight to prove his guilt or innocence. If you lost the fight, you were charged as a liar and the criminal was believed to be innocent. If you won, the criminal was believed to be guilty.

• Laws of the Middle Ages were unfair.

• Fighting was a good way to determine guilt or innocence during the Middle Ages.

• Most people lied about crime in the Middle Ages.

• Individuals that were innocent of crimes often won the fighting challenges.
