Solution: informal
Explanation: 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

Problem: Person1: Hi , Mr . Zhang . What ' s wrong ? You don ' t look so happy . How was your date ?
Person2:I was turned down again . It ' s frustrating . I guess you ' Ve got to teach me some skills .
Person1: Me ? I ' m even less experienced than you are .
Person2:At least you know what American women generally like in a man .
Person1: Believe it or not , I guess American women like a man in good shape , which Chinese women may not care about so much . That ' s my honest opinion . I know you have been trying very hard .
Person2:American men are naturally taller than Chinese men . So even if I exercise , there aren ' t many chances .
Person1: No , that ' s not true . I ' Ve met two American women who were married to Chinese . But those Chinese look very strong and healthy . So if you exercise more often , I bet it will surely be easier for you to date American girls . How old is Jacky Chan ? He ' s small and short . But I bet he can have any American woman he wants .
Person2:You know , that ' s going to be a tremendous change for me . Because I never exercise .
Person1: Why don ' t you try then ? Even if it doesn ' t help you find an American girl , you could still have a stronger and healthier body . You won ' t lose anything by doing that .
Solution:
informal
