Task: Question Answering
Input (English): Passage: Vance "Van" Wilder is a confident and sardonic seventh year senior at Coolidge College who is popular among most of the student body. With no ambition to graduate, Van spends his days driving around campus in his customized golf cart, posing nude for figure drawing classes, organizing soirees and fundraisers for his peers. Among his friends are his roommate and close confidant Hutch and his newly hired assistant Taj Badalandabad, a sexually repressed foreign exchange student from India.
Upon learning that his son is still in school, Van's father arrives at Coolidge intent on bringing him home. When Van refuses, his father decides to sever Van's financial support. Faced with disenrollment due to unpaid tuition, Van seeks a payment extension from the registrar, Deloris. After Van has sex with her, Deloris hands him the paperwork for an extension, which Van realizes he only needed to ask for in the first place.
Gwen Pearson works for the school paper, and despite her talents for journalism, her articles do not generate interest from the student body. Her editor assigns her to get an "unattainable" human interest story on Van Wilder as he normally refuses to do interviews for the paper. After a couple of attempts to get money fast, Van is approached by the Lambda Omega Omega fraternity, offering to pay him a thousand dollars to throw them a blowout party and boost their popularity.
Overhearing two of the Lambdas expressing their excitement over the party's success and their satisfaction with Van's work, Gwen writes a story crediting Van as the host of the party. Though Van hates the article at first, he realizes it can be the "cash cow" he needs to stay in school. Van eventually agrees to sit down with Gwen for the follow-up piece after losing a hockey bet to her. 
Question: What is the name of the person Vance has sex with?
Output (English): Deloris.
