Answer:
One way the author uses irony to convey his message is By having the "winner" of the Lottery of Fairness and Benevolence punished, he shows that society is dysfunctional.
Step-by-step explanation:
The complete idea of this excerpt about having a lottery with the topic of crime and punishment is a pure irony element, there are so many points of irony such as the name of the lottery "Lottery of Fairness and Benevolence" while perhaps a person who is not guilty will pay for what others have done, making the system completely dysfunctional. Then the fact that it does not matter how old the person to be punished will be, and the necessity of having soldiers around.
