I want you to think about examples from the recent pandemic. You need to think of two specific (giving company names) examples- one of a product the experienced a shock to their demand (or a shift of their demand curve), another of a product that experienced a shock to their supply (or a shift of their supply curve). The shift may have been brought about by the pandemic affecting a variety of factors-the price of inputs, access, technology, changes in preferences, price of related products, changes in expectations, changes in the number of producers or consumers, and all the other factors you've learned about.
