   • The number of products in inventory
3. What did the false-decline worked example ask retailers to measure?
   • The average basket size
   • Only the number of blocked fraud attempts

   • The model’s response time
4. Why evaluate retail outcomes by subgroup?
   • It removes the need to monitor returns

   • An alternative route and a way for staff to correct the issue
   • A higher price
   • A hidden score only
   • No explanation or recourse
8. Why monitor new products, promotions, and seasons?
   • They prevent the need for versioning
   • They make all recommendations more accurate
   • They eliminate false declines
   • They can change behavior and cause model or policy drift
