I have a test where I am given the following article, what is an answer for the question: Who is Jim's love interest's sister? ?

Seventeen-year-old identical twin sisters Jane and Roxy Ryan are completely different and never see eye to eye. They live with their widowered father, and attend the fictional Atta Westland Grove High Van School in Syosset, a suburban Long Island town. Over a 24-hour period, the two begrudgingly journey together into the city for Jane, an uptight overachiever, to deliver a speech to qualify for a prestigious college scholarship abroad, and for Roxy, a laid-back punk-rock rebel, to get backstage at a music video shoot so that she can give her demo tape to the group.
Jane and Roxy board the train into New York but are soon thrown off together after Roxy is found without a ticket. At the station, Jane bumps into Jim, and they flirt back and forth before he gets on the train. Meanwhile, Roxy becomes unknowingly involved in a shady black-market transaction after an illegal chip device is mistakenly planted in her bag. Bennie Bang, the man behind the plan, offers Roxy a ride in a swanky limousine and she accepts, dragging Jane along who is reluctant about getting into cars with strangers. He locks them inside but they escape through the sun roof and he chases them into the city subway where they help one another to fight him off.
