Answer:
Situational irony is when the expected action or response does not happen in reality. But, the opposite happens. In the passage: “Most of the aunt’s remarks seemed to begin with ‘Don’t,’ and nearly all of the children’s remarks began with ‘Why?’” is the situational irony.
The points that state the situational irony are:
The dialogues of the aunt and the children are given significance among the other characters.
All the other lines focus on the reaction of the characters after the story is narrated.
There is a sense of opposition between the aunt and the children.
Thus, the uncompromising attitude is conveyed through the word, ‘Why?’. The expectations that the aunt had on the children does not work out.
