Task: Question Answering
Input (English): Passage: In Spring 1989, sisters, Alex, and Annie Morrell, finish prep school and return home to start college. Their mother, publishing heiress Anne Scripps, welcomes them in her New York mansion. Anne has recently divorced her husband Tony, and is still struggling with the divorce. Nonetheless, she is happy with her new boyfriend, much younger Scott Douglas, a volatile-tempered young man whom she marries only months after their first meeting.
From the start, Alex is uncertain if she should trust Scott, having heard stories about a possible violent past. When Anne announces that she will be having a baby, Scott is distrustful to notice how Alex reacts with doubt about the news. To get rid of her, he claims that he has found marijuana in Alex's bedroom. Alex denies the accusation, but Anne defends her boyfriend, who forces Alex to leave the house.
Shortly after Anne and Scott's baby, Tori's, birth in June 1990, Scott gets violent and beats up Anne for inviting Tony's family for the baby's coming out party. Alex and Annie encourage their mom to leave Scott, but Anne forgives him after a couple of months. By June 1991, she and Scott are a happy couple again. On Alex's 21st birthday, Scott lashes out at Anne again when he finds her smoking in the same room as Tori, and then throws a guest, Stacey, off the stairs. Enraged, Alex dares Scott to hit her, and the police interrupts their fight, only to have Scott lie about the situation. A similar occurrence takes place at a formal ball, where Scott pushes around Anne in front of her friends. As they leave, the fight continues in the car, and Scott eventually throws her out while speeding. 
Question: What is the first name of the people whose mother welcome them in her New York mansion?
Output (English): Alex.
