Chapter 5: Conclusion Final Exam: Question 10

The New York City Bodega Association is looking to create an app that will help them keep track of their unique, versatile inventory and help customers look up whether items are in stock before visiting the bodega.

The last part of the question, there is a mention for checking whether the item(s) is/are in stock. Does this not inform us that there is chance of using computed pattern along with polymorphic patter?

Thanks for your help.
