Task: Question Answering
Input (English): Passage: Joey and Turkey are members of the Wanderers, an all-Italian-American street gang. In the Bronx, New York, Joey tries to dissuade Turkey from joining a rival gang, the Fordham Baldies. Before Turkey can ask, Terror's girlfriend Peewee overhears Joey insulting the Baldies, calling them a "bunch of pricks with ears". Joey and Turkey flee and the Baldies chase them. Richie—the leader of the Wanderers—and Buddy come to help but they also flee from the Baldies. After being cornered, the Wanderers are helped by a tough stranger named Perry, who has recently moved to the Bronx from New Jersey. After much persuasion, Perry joins the Wanderers.
In school, the Wanderers get into a racial dispute with another gang, the Del Bombers who are all African-American. Both gangs agree to settle their dispute, seemingly a street fight, but the Wanderers struggle to find a gang willing to back them. With no other options, Richie asks his girlfriend's father, local mafia boss Chubby Galasso, who agrees to help solve the gangs' dispute.
During a game of "elbow-tit", Richie gropes a woman called Nina. He feels ashamed of himself, apologizes for his actions and persuades Nina to accept Joey's telephone number. The Wanderers then decide to follow Nina in Perry's car.
After Perry becomes lost, the Wanderers are attacked by an all-Irish-American street gang called the Ducky Boys. They escape after Perry's arm is broken.
While drunk, the Baldies are tricked into joining the Marines. Before reporting for training, they decide to crash Despie's party, where Turkey—who has recently joined the Baldies—is told to draw the Wanderers outside. After drawing them out, Turkey realizes the Baldies have abandoned him. He tries to chase them but fails. Upset, Turkey visits a nearby Catholic church. After being spotted by a member of the Ducky Boys attending mass, Turkey is chased down the street. After climbing a fire escape ladder in an attempt to escape, he falls to his death. 
Question: Who persuades a woman who was groped to accept Joey's phone number?
Output (English): Richie.
