Green Card renewal

My friend summited his green card renewal about 2 months ago. He just got a REQUEST FOR EVIDENCE. Evidence they are requesting may include the following legible photocopy of previous Permanent residence card, Form I-551 or I-151, photocopy of passport or any other document received from the government relating to his lawful permanent resident status.

He does not have his expired card because he lost and it has been expire for many years now. he does have a copy of the front of it but not the back. He does not have a passport. or any entry stamps. How can he respond to this request if he doesnt have what they are requesting?
