Question: State name of students who have the longest duration of absense from school and do not have payment due.
Evidence: longest duration of absence from school refers to MAX(month); do not have payment due refers to bool = 'neg';

SQL:
SELECT T1.name FROM longest_absense_from_school AS T1 INNER JOIN no_payment_due AS T2 ON T1.name = T2.name WHERE T2.bool = 'neg' ORDER BY T1.month DESC LIMIT 1
