Question: State the district and region for loan ID '4990'.
Evidence: A2, A3 contains the information about district and region respectively.

SQL:
SELECT T2.A2, T2.A3 FROM account AS T1 INNER JOIN district AS T2 ON T1.district_id = T2.district_id INNER JOIN loan AS T3 ON T1.account_id = T3.account_id WHERE T3.loan_id = 4990
