Task: Question Answering
Input (English): Passage: Fed up with her dead-end job with a Minneapolis car rental agency, Martha quits, cashes her final paycheck, and uses the money to purchase an airline ticket to the least expensive international destination she can find - London. At the airport, she meets Daniel, a successful music label executive, who covertly arranges for her to be upgraded to First Class and seated next to him on the flight. When she sells the ticket to another passenger and Daniel finds his seatmate is an obnoxiously loud woman instead of the girl of his dreams, he moves back to the Economy section and takes the vacant seat next to Martha. Before landing in London, he offers her the use of a deluxe suite in a luxury hotel at his company's expense in exchange for a lunch date the following day.
Through a series of flashbacks and flashforwards, we learn Laurence, a former bridge champion who now teaches the game to wealthy women, went to the airport to pick up Daniel but missed him because the flight landed early. Instead, he literally runs into Martha, who hits him with a luggage cart while searching for the exit. She coerces him into taking her into the city and invites him to the suite for dinner. While she is in the bathroom, a bouquet of flowers from Daniel is delivered to the suite, and when Laurence sees the attached card, he departs without explanation.
The following day, Martha meets struggling actor Frank, who has fled an audition in a panic and has gone to the park to console himself with a half-bottle of whiskey. Having heard about her from Daniel, he realizes who she is and calls Laurence to boast that he is about to make her his conquest. He takes her to a nearby art gallery. Martha slips away and heads for the exit, where she reunites with Laurence, who was looking for the pair. He invites her back to his flat and she accepts. 
Question: What is the first name of the person who sells her ticket to a fellow passenger?
Output (English): Martha.
