Task: Question Answering
Input (English): Passage: Joan Prescott is a vacuous and flirtatious daughter of the wealthy Montana rancher, John Prescott.  On the train, Joan's sister, Elizabeth tells her she's in love with Jeff.  Jeff is more smitten with Joan and kisses her. Joan then impulsively gets off at the next whistle stop, where she meets Larry, a Texas cowboy. He is a rancher on John Prescott's land, and does not know who Joan is. He expresses dismay at how spoiled Prescott's daughters are.  Joan conceals her identity, refusing to say her name.  She tells him to think of something he loves and call her that, and he chooses "Montana."
Joan and Larry fall for one another and are married. When they return to her father's ranch, the couple are nervous that he will not approve of the pairing.  However, to their surprise, John Prescott is delighted for the couple and believes Larry is the kind of person who can finally settle Joan.  At their party, celebrating their nuptials,  Joan sees Jeff, with whom Joan does a daring dance. As they finish dancing, Joan and Jeff share a lingering kiss. After Jeff and Larry come to blows, Joan is embarrassed that Larry resorted to violence.
As Joan became familiar with Larry's posse of cowboy friends, she wants Larry to be accustomed to her group of highbrow city friends who are in Montana with John Prescott.  She wants to go back to New York where the couple can live comfortably, but Larry feels it is his duty as a husband to provide for his wife and having her father take care of him is not an option. 
Question: What is the full name of the character who Larry does not want to take care of him and his wife?
Output (English): John Prescott.
