Question: Which business had the most number of inspections? Give the Id number for that business.
Evidence: the most number of inspections refers to MAX(COUNT(business_id)); Id number for that business refers to business_id;

SQL:
SELECT business_id FROM inspections GROUP BY business_id ORDER BY COUNT(business_id) DESC LIMIT 1
