                        a.   Ishita wants to create a variable in Scratch to store the user's name. She is currently using
                           only one sprite but plans to add more sprites later in the project. Which type of variable
                           should she create to ensure that its value can be accessed by all sprites in the project?
                        b.   Luv wants to create a project in Scratch where his sprite bounces when it touches the edge
                           of the stage. Which block category and specific block should he use for this?
