Yesterday I had a man come up to me holding a book and ask , " Will this book tell me what I need to know ? " I asked him what he needed to know , but also told him that I had n't read the book so I really could n't be sure exactly what information it contained . He then asked if he was allowed to sit down and look through the book before checking it out . I told him he could do that .

Generate a question about the above context.
Why did the man asked me what he asked me ?
