You will be given a definition of a task first, then some input of the task.
You are given a dialog between 2 or more individuals. Within the dialog, there will be clues that indicate two individuals were or are dating. You will be prompted at the end to answer which Speaker (or named individual) is dating which other Speaker (or named individual).

Speaker 1: Ooh! How was Kathy's play?
Speaker 2: Well, Kathy gets half-naked and simulates sex with a real good lookin' guy.
Speaker 3: Yeah, it's like someone literally wrote down my worst nightmare and then charged me $32 to see it!
Speaker 1: That's a good idea for a business!
Speaker 3: I'm totally screwed. Okay, they are gonna be hot and heavy on stage every night, and then they're gonna go to their cast parties and he's gonna try to undermine me. Y'know it'll be like, "So where's your boyfriend, what's-his-name, Chester?" And she'll go, "No-no-no, it's Chandler." And he'll go, "Whatever. Ha-ha-ha-ha!"
Speaker 4: That-that is a good trick.
Speaker 3: All right, look, look, what am I gonna do?
Speaker 4: Chandler, look they're actors. They're there to do a job, just 'cause they work together, doesn't mean they're gonna get together. I mean just 'cause it happened with Susan Sarandon and Tim Robbins, it doesn't mean it's gonna happen with them.
Speaker 2: Oh-oh, Alec Baldwin and Kim Basinger.
Speaker 4: Tom Cruise and Nicole Kidman.
Speaker 2: Yeah.
Speaker 1: Hey, Mel Gibson and Clint Eastwood.
Speaker 2: They're not a couple!
Speaker 1: Oh-okay, I get the game now.
Speaker 4: Okay look, look, let me ask you a question, when they were doing it on stage, was it like really hot?
Speaker 2: Oh yeah!
Speaker 4: Well okay, so then you're fine. The rule is when two actors are actually doing it off-stage all the sexual tension between them is gone. Okay? So as long as it's hot onstage you got nothing to worry about. It's when the heat goes away, that's when you're in trouble.
Speaker 3: Really?
Speaker 4: Look, you guys have been to every play I've ever been in, have I ever had chemistry on stage?
Speaker 2: No.
Speaker 4: Noooo!! Kathy is or was dating which Speaker?
Output:
Speaker 3
