I am writing about Walmart and its competitors in an Oliogposlic competition. I need help with these questions please.

Are there any recommendations that are related to recent events, and in its associated market, which is an oligoploistic market, and are the logical and feasable?

Explain how any significant recent events or changes in this market have affected Walmart, such as mergers and acquistions, technological change, legal issues, market demand trends, and other events.
