Answer:
In Excel, a scenario is a set of data inserted in the spreadsheet that is being used, which forms a variable that can be modified and, therefore, replaced in said spreadsheet together. Thus, for example, if cells A1: D4 contain data that is specific to an eventual particular situation that can occur in 3 different ways, there will be 3 scenarios containing data in that range of cells that can be modified, thus modifying the final results of spreadsheet.
