I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Shame Movie plot: Brandon, a New York City executive, makes eye contact with a woman wearing an engagement ring on the subway during his morning commute. She reciprocates, but when they exit, she disappears into the crowd. He masturbates in the bathroom at work. Brandon and his married boss, David, hit on women at a club; later, Brandon has sex on a quiet street with the woman David was pursuing. Brandon has been ignoring calls from sister Sissy, a lounge singer. He arrives at his apartment to find her in his shower. Sissy has a few gigs in the city and asks to stay; he later hears her pleading with her lover on the telephone not to reject her. After Brandon's company computer system is infected with a virus, they find his hard drive was full of pornography. David assumes Brandon's intern is responsible. Brandon rebukes Sissy for balancing precariously on the subway platform edge. Later, he and David watch her perform "New York, New York" in a bar, which makes Brandon emotional. David flirts with her and notices the scars of self-inflicted wounds on her arms. Sissy has sex with David in her brother's bedroom while Brandon, disgusted, goes running. Later that night, Sissy attempts to get in bed with Brandon; he orders her out of the room. Brandon goes on a date with co-worker Marianne; Marianne, recently separated, has a positive attitude toward commitment, while Brandon dislikes the idea of marriage and admits that his relationships have never lasted longer than four months. They go home separately. That night, Sissy discovers Brandon masturbating in his bathroom. He attacks her and accuses her of spying on him. She finds his laptop open on a pornographic webcam site. Brandon slams the laptop shut and a disturbed Sissy leaves. Brandon disposes of his pornography, sex toys and laptop. At work, he kisses Marianne and the two get a hotel room, but Brandon cannot maintain an erection. It becomes apparent that Brandon cannot perform when emotions and affection are involved, but rather when he's feeding his sexual addiction.... My question: What transportation is Brandon using in this scene?
The answer to this question is:
The subway.
