The DBA denormalized some of the data in the Sports Physical Therapy database to improve performance, and one of the resulting tables is the following:

Patient (PatientNum, LastName, FirstName, Address, City, State, ZipCode, Balance, TherapistID, LastName, FirstName)

Which field or fields cause the table no longer to be in third normal form? In which normal form is the denormalized table? What other problems do you see on the table?
