Task: Question Generation
Input (English):  Following Anne of Green Gables (1908), the book covers the second chapter in the life of Anne Shirley. This book follows Anne from the age of 16 to 18, during the two years that she teaches at Avonlea school. It includes many of the characters from Anne of Green Gables, as well as new ones like Mr. Harrison, Miss Lavendar Lewis, Paul Irving, and the twins Dora and Davy.Anne is about to start her first term teaching at the Avonlea school, although she will still continue her studies at home with Gilbert, who is teaching at the nearby White Sands School. The book soon introduces Anne's new and problematic neighbor, Mr. Harrison, and his foul-mouthed parrot, as well as the twins, Davy and Dora. They are the children of Marilla's third cousin and she takes them in when their mother dies while their uncle is out of the country. Dora is a nice, well-behaved girl, somewhat boring in her perfect behaviour. Davy is Dora's exact opposite, much more of a handful and constantly getting into many scrapes. They are initially meant to stay only a short time, but the twins' uncle postpones his return to collect the twins and then eventually dies. Both Anne and Marilla are relieved (Marilla inwardly, of course) to know the twins will remain with them.
Other characters introduced are some of Anne's new pupils, such as Paul Irving, an American boy living with his grandmother in Avonlea while his widower father works in the States. He delights Anne with his imagination and whimsical ways, which are reminiscent of Anne's in her childhood. Later in the book, Anne and her friends meet Miss Lavendar Lewis, a sweet but lonely lady in her 40s who had been engaged to Paul's father 25 years before, but parted from him after a disagreement. At the end of the book, Mr. Irving returns and he and Miss Lavendar marry.
Anne discovers the delights and troubles of being a teacher, takes part in the raising of Davy and Dora, and organizes the A.V.I.S. (Avonlea Village Improvement Society) together with Gilbert, Diana, and Fred Wright, though their efforts to improve the town are not always successful. The Society takes up a subscription to repaint an old town hall, only to have the painter provide the wrong color of paint, turning the hall into a bright blue eyesore.
Towards the end of the book, Mrs. Rachel Lynde's husband dies and Mrs. Lynde moves in with Marilla at Green Gables, allowing Anne to go to college at last. She and Gilbert make plans to attend Redmond College in the fall.
This book sees Anne maturing slightly, even though she still cannot avoid getting into a number of her familiar scrapes, as only Anne can some of which include selling her neighbor's cow (having mistaken it for her own), or getting stuck in a broken duck house roof while peeping into a pantry window.
Output (English): Why does Anne agree to take care of the twins Davy and Dora?
