Task: Question Generation
Input (English):  The heroine, the devout Laura Montreville, is pursued by the lecherous rake Colonel Hargrave. Realising that he has offended her, the Colonel gives Laura a more honourable proposal of marriage, but she refuses him gently on grounds of moral incompatibility, despite this meaning that she would miss out on the Colonel's title and fortune. Captain Montreville, Laura's father, finds out that Laura's annuity is not assured, and so takes Laura to London to fix the matter. Without the knowledge of her father, Laura consents to marry the Colonel eventually, if he can reform himself within two years.
When she is left without any money in London, she decides to support her ailing father by selling sketches. During her time in London, a man named Montague De Courcy begins to fall in love with her. De Courcy buys Laura's sketches in secret. Hargrave follows Laura to London, and he becomes involved in an affair with a married woman. Hargrave meets Laura in the shop where she sells her sketches and paintings, and accompanies her home and harasses her. Hargrave's affair is found out by his lover's husband, and the two men duel. Hargrave wounds the husband, and then goes to Laura, urging her to marry him before she finds out about his affair. Because Hargrave threatens to kill himself, Laura faints, and is found by her father, who then realises that Hargrave has been threatening his daughter, and he has been encouraging Hargrave. This causes Captain Montreville such grief that he dies the next morning. When Captain Montreville dies of his illness, Laura goes to live with Lady Pelham, her maternal aunt. Lady Pelham helps Laura receive her annuity, but she is not religious and colludes with Colonel Hargrave. Laura learns of Hargrave's duel, and resolves to refuse him. Hargrave attempts to persuade her to marry him by more drastic measures - having her arrested under false pretenses, tricking her into joining a gambling party, and when Lady Pelham dies, Hargrave kidnaps Laura and takes her to the wilderness of America. He plans to rape and then force Laura into marriage - she fakes her own death by escaping down the rapids in a canoe, which she ties herself to. Hargrave commits suicide, and Laura returns to her home country, where she marries Montague De Courcy and has five children with him.
Output (English): What does Laura sell to financially support her ailing father?
