Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: In Edwardian London, 1910, Bert entertains a crowd as a one-man band when he senses a change in the wind. Afterwards, he directly addresses the audience, and gives them a tour of Cherry Tree Lane, stopping outside the Banks family's home. George Banks returns home to learn from his wife, Winifred, that Katie Nanna has left their service after Jane and Michael ran away again. They are returned shortly after by Constable Jones, who reveals the children were chasing a lost kite. The children ask their father to help build a better kite, but he dismisses them. Taking it upon himself to hire a new nanny, Mr. Banks advertises for a stern, no-nonsense nanny. Instead, Jane and Michael present their own advertisement for a kinder, sweeter nanny. Mr. Banks rips up the letter, and throws the scraps in the fireplace, but the remains of the advertisement magically float up, and out into the air.
The next day, a number of elderly, sour-faced nannies wait outside the Banks' home, but a strong gust of wind blows them away, and Jane and Michael witness a young nanny descending from the sky using her umbrella. Presenting herself to Mr. Banks, Mary Poppins calmly produces the children's restored advertisement, and agrees with its requests, but promises the astonished banker she will be firm with his children. As Mr. Banks puzzles over the advertisement's return, Mary Poppins hires herself, and convinces him it was originally his idea. She meets the children, then helps them magically tidy their nursery through song, before heading out for a walk in the park.
