Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.
Input:  Person1:     What ’ s up ? You don ’ t look too good . 
 Person2:  Yeah , my head hurts , that ’ s all . I ’ Ve been in physics class all day . It ’ s killer ! 
 Person1:      I liked physics . It ’ s all math , really . arcs , curves , velocity , cool stuff . 
 Person2:  Yeah , yeah , but today ’ s lesson was all about the creation of the universe . 
 Person1:      A physics class about the creation of the universe ? That ’ s some pretty unscientific language there . Sounds more religious to me . 
 Person2:  It ’ s all religion . Take the theory of the Big Bang.How is it possible that all of the stuff in the universe comes from an explosion ? That ’ s no better than Atlas carrying the globe on his back or African myths about turtles and stuff . 
 Person1:      Turtles ? Whatever ... Look , all that ’ s required for the creation of matter an imbalance of particles and anti-particles . At least , that ’ s what the math says . 
 Person2:  Math , sheath . What ’ s the evidence ? 
 Person1:      There is evidence ! You know Edwin Hubble ? He ’ s the guy who in the early twentieth century was the first scientist to measure the drift of matter in the universe , thus advancing notions of an expanding universe . What would it be expanding from ? Well , the Big Bang ... DUH ! 
 Person2:  Anyway , it ’ s just a theory . Why do people go around touting theories ? Where ’ s the scientific rigor in that ? 
 Person1:      Dude , don ’ t equivocate . A theory only becomes a theory after withstanding rigorous testing . You slept through class , didn ’ t you ?
