Task: Question Generation
Input (English): Passage: Dinky Bossetti is a 15-year-old girl who was adopted as a baby. She appears to have little acceptance in her social circle, although it is not obvious which came first - her antisocial attitude or her being rejected by her peers. Her adoptive mother Rochelle is disappointed that the daughter she chose has no interest in "feminine" things, such as makeup and nice clothing. Her classmates ostracize, taunt, and throw things at her regularly. Dinky finds solace in her "Ark", a small cabin-boat beached on a lake shore. In and around the boat, Dinky has collected a menagerie of abandoned animals.
As the story begins, Dinky is befriended by the new school guidance counselor Elizabeth Zaks, who recognizes her intelligence and spirit. Dinky becomes convinced that she is the abandoned daughter of Roxy Carmichael, a minor film star who left town for Hollywood 15 years ago after giving birth to a baby girl out of wedlock. Roxy has been invited to return to town to assist in the dedication of a new municipal building, and she has accepted. The news of her return stirs up old jealousies and insecurities: old schoolmates start acting in irrational ways, while Denton Webb, the husband she abandoned when she left town, becomes so obsessed by the idea of her return that his wife Barbara moves out.
Output (English): What is the first name of the person that has caused Denton Webb to become obsessed by the thought of their return?
