Hello!  Can you please list all of the gymnast IDs and their associated hometowns?
SELECT T1.Gymnast_ID, T2.Hometown FROM gymnast AS T1 JOIN people AS T2 ON T1.Gymnast_ID   =   T2.People_ID
gymnast IDs and their associated hometowns requires a JOIN between two tables, one holding gymnast information and another holding people information; gymnast IDs are stored in a 'Gymnast_ID' column; hometowns are stored in a 'Hometown' column;
