Given the task definition and input, reply with output. 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'.

Person1: Good afternoon , you look a little stuck . Can I help ?
Person2:The thing is , I've got all of this information here , all of these leaflets , but I can't make head nor tail of them !
Person1: I see . What is it exactly that you are interested in ?
Person2:I'm not sure which would be better for me ; buying some insurance or putting my money in a Savings Deposit .
Person1: Well , that all depends on how much you want to invest .
Person2:I was thinking of around 10,000 RIB .
Person1: That's a nice round figure to deal with ! OK , if you were to buy this insurance policy , your yearly fixed income from it would be 94.35 RIB .
Person2:And for the Savings Deposit ?
Person1: For the Savings Deposit you could actually get more . You see , in time deposit , the interest rate is 1.58 % after the 20 % interest tax . So , technically you could get more than a third more .
Person2:Wow ! A third more ? Very good .
