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'.

Let me give you an example: Person1: Hey man , you wanna buy some weed ?
Person2:Some what ?
Person 1:Weed ! You know ? Pot , Ganja , Mary Jane some chronic !
Person2: Oh , umm , no thanks .
Person1: I also have blow if you prefer to do a few lines .
Person2: No , I am ok , really .
Person1: Come on man ! I even got dope and acid ! Try some !
Person2: Do you really have all of these drugs ? Where do you get them from ?
Person1: I got my connections ! Just tell me what you want and I ' ll even give you one ounce for free .
Person2: Sounds good ! Let ' s see , I want .
Person1: Yeah ?
Person2:I want you to put your hands behind your head ! You are under arrest !
The answer to this example can be: informal
Here is why: Based on the conversation, we can see that there is a presence of exclamation which is not present in a formal discussion. Therefore this is an informal conversation

OK. solve this:
Person1: I think we have had a very pleasant conversation , haven't we ?
Person2:Yes , I think so too .
Person1: Do you have any other questions ?
Person2:Let me think ... I want to know if the company can provide free accommodation for a new employee .
Person1: I'm sorry we can't now .
Person2:I really hope that your company could provide living places ; otherwise I have to rent a house to live .
Person1: Maybe the company will build dormitory for the employees in the future .
Person2:That would work too .
Person1: Anything else ?
Person2:Some companies will pay part of the phone bills for the employees . Will this company do so ?
Person1: I'm sorry we won't do so for a new employee . We only provide this benefit to employees who have made significant contributions to the company .
Person2:I understand . Will the company provide training ?
Person1: Yes , we will , and the staff will have a chance to travel every year .
Person2:That's great . Thank you very much .
