How is the end of chapter two an example of situational irony?

My copy is just one story: it has no chapters. Can you tell me what is happening at the end of your chapter 2?

With situational irony, the outcome of the situation is not what the reader expected to happen. This is definitely a twist in the plot. One hoped the Whites would receive the $200 but did not expect their son to be killed in a machine accident and then receive $200 as compensation for his loss of life. The reader did not expect the Whites to receive the money this way.
