You are given a dialog between 2 or more individuals. You need to generate the number of the speaker (e.g. 1 for Speaker 1) who had the most lines in the dialog. If there is a tie, output the answer '0'.

Speaker 1: Uh-oh. It's Scary Scientist Man. 
Speaker 2: Ok, Phoebe, this is it. In this briefcase I carry actual scientific facts. A briefcase of facts, if you will. Some of these fossils are over 200 million years old. 
Speaker 1: Ok, look, before you even start, I'm not denying evolution, ok, I'm just saying that it's one of the possibilities. 
Speaker 2: It's the only possibility, Phoebe. 
Speaker 1: Ok, Ross, could you just open your mind like this much, ok? Wasn't there a time when the brightest minds in the world believed that the world was flat? And, up until like what, 50 years ago, you all thought the atom was the smallest thing, until you split it open, and this like, whole mess of crap came out. Now, are you telling me that you are so unbelievably arrogant that you can't admit that there's a teeny tiny possibility that you could be wrong about this? 
Speaker 2: There might be, a teeny, tiny, possibility. 
Speaker 1: I can't believe you caved. 
Speaker 2: What? 
Speaker 1: You just abandoned your whole belief system. I mean, before, I didn't agree with you, but at least I respected you. How, how, how are you going to go into work tomorrow? How, how are you going to face the other science guys? How, how are you going to face yourself? Oh! That was fun. So who's hungry?
