Answer:
The children's aunt offers to tell them a story because:
A. She wants to entertain the children to keep them quiet.
Explanation:
n the short story "The Story-Teller" by Saki, an aunt is onboard a train with her two nieces and a nephew. In the same carriage is an "unsympathetic" bachelor - or at least, that is how the aunt sees him. The children are restless, constantly asking questions, moving around, smacking the cushions of the seats, and even reciting poems. When the bachelor seems to be getting angry, the aunt decides to entertain the children with a story, as a way to keep them quiet and prevent the bachelor from complaining. However, her story is filled with flaws. Even its attempt to teach the children a lesson about being good and well-behaved fails. The bachelor than intervenes and ends up telling them a much better story.
