You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.

Q:  Person1:       Good morning golf aficionados ! My name is Rick Fields , and you guessed it , I am here with my main man , Bob Copeland .  
 Person2:Thank you , Rick ! As you can see , ladies and gentleman , we are here in beautiful Pebble Beach where the top golfers in the world are trying to win the grand prize of one million dollars !  
 Person1:        Whoa , that ’ s a lot of cash ! Let ’ s go to the course and see how Tiger Woods is doing .  
 Person2:All right , we are here at the eighth hole . It ’ s a par four , and has some very difficult hazards which many golfers find difficult to avoid . Although , I did see Jack Nicklaus hit a hole in one on this very same hole !  
 Person1:        Tiger Woods is about to tee off , and let ’ s see if he has the same luck as Jack . Tiger is asking his caddie for his driver and , he seems to be very nervous .  
 Person2:Oh no ! Not a good swing at all ! It ’ s definitely not his day today . On the seventh hole he got a bogey and before that he barely made par . He will definitely not get a birdie on this shot .  
 Person1:        It seems that his ball has flown somewhere deep in the trees . He is having a hard time finding it and even his caddie has climbed a tree to try and spot it .  
 Person2:Oh no ! A bear ! Run , Tiger , run ! Somebody call animal control !

Q:  Person1:       Did you watch the Premiership last night ? 
 Person2:Yes , I watched United play Chelsea . What a fierce battle ! allay were engaged in intensive pressing and tackling in midfield . Well , it was not like a normal English League match . 
 Person1:        No , it wasn't . Rather , it looked like a Bundesliga match , where physical contact is so frequent . English League teams are apt to pass the midfield quickly with long passes . It seems to me English soccer players are very gentlemanly . As Diego Maradona spoke teasingly , they often knew only chasing hard after the ball , but forgot to steal it . 
 Person2:Haha . That's probably why slide tackle and fouls are less common , and offsides more frequent in English League matches than those on the Continent . And the ball is often kept flying overhead , drawing beautiful curves in the sky . Such games are quite pleasing to the eye . 
 Person1:        Which team do you back then ? 
 Person2:I'm a firm United supporter . I like their playing style . The Reds always have several excellent wing-backs , Like Riggs , Peckham and Gary Neville . They often make wonderful crosses when they assist in attacking . 
 Person1:        But the Reds keep a weak midfield . I think Juventas of Italian Series A have always maintained a very formidable midfield . It is the main source of its strength .
