review the programming scenarios given below, and explain why a multi-threaded or single-threaded solution is more effective for each.

• A printer that is performing the job of printing a set of documents
• An application that allows the graphical user interface (GUI) to remain responsive while processing a large number of files
• A Python webserver that listens for requests, reads them, and pushes the data in the database
• A shell program that closely monitors its own working space, such as open files, environment variables, and current working directory
• A program that calculates a large number of payments where each calculation is independent of other payment calculations

Part Two: Use the following guidelines to create three additional programming scenarios similar to the ones given in Part One.

• Write Scenario One such that the most effective solution is a single-threaded process.
• Write Scenario Two such that the most effective solution is a multi-threaded process.
• Write Scenario Three such that the most effective solution is either a single-threaded or multi-threaded process.
