Task: Question Answering
Input (English): Passage: In the early Sixties, Corinne Walker is a girl who is skeptical about God. After her brother is stillborn, her parents' marriage disintegrates over the course of several years. As a teenager, she meets Ethan Miller, a budding musician in local rock band The Renegades. The two marry after Corinne gets pregnant and have a daughter, Abigail. While touring with Ethan's band, their bus crashes into a river. Ethan rushes to save Abby, and Corinne pleads with God to save the child. Abby is pulled out of the bus before it sinks into the water, and Ethan believes that God wanted them to live. Ethan and Corinne grow more fond of Jesus, eventually giving themselves over to a radical New Testament church.
As adults, Corinne and Ethan live with their children—Abigail and Lilly—amid a community of self-described "Jesus freaks". Corinne's daily life consists of hours of Bible study and alternative family practices. The husbands are told by Pastor Bill that they should pay more attention to their wives' sexual needs after a fellow husband's indiscretions caused his wife to leave with their children. Corinne's closest friend Annika also warns her about keeping the marriage alive by trying new things, such as drawing their husbands' penises.
One day, Corinne's younger sister, Wendy, shows up on her doorstep after ending yet another bad relationship, and moves in with them. Their father comes over for dinner, and says that children are the most important things in life. He takes responsibility over how losing their baby brother caused him to wreck his marriage. Later, Ethan finds Lilly playing with some cocaine she found in Wendy's suitcase. He and Corinne flush the drugs down the toilet, and Wendy storms off. 
Question: What is Abigail's nickname?
Output (English): Abby.
