Question: With the biggest budget for the "Food", what was the remaining of it?
Evidence: remaining of budget refers to remaining, biggest budget for 'Food' refers to MAX(budget.amount) where category = 'Food'

SQL:
SELECT remaining FROM budget WHERE category = 'Food' AND amount = ( SELECT MAX(amount) FROM budget WHERE category = 'Food' )
