Me llamo Isabel. They are asking your name. I highly recommend using Spanishdict.com it is very good at translating anything you need and has verb conjugations, etc.
What does that mean please tell me
Lima, Perú since Lima is the capital of Peru its the folk center of Peru. I am still not sure what you mean by "folk center".
