1. what does redo allow users to do?

restore your school report after accidentally saving a blank document over it
delete something, change your mind and use undo, then change your mind and use redo to delete again
copy and paste and use the redo button to continue copying and pasting
delete something and use redo to keep deleting

Explanation:

• For question 9: Multitasking means handling multiple tasks simultaneously. The first option is context - switching, the second is single - tasking, and the fourth is sequential tasking.
• For question 10: Redo reverses an Undo action. Option 1 is about file recovery (not Redo), option 3 is about repetitive actions (not the main function of Redo), and option 4 is incorrect as Redo doesn't "keep deleting" but reverses an Undo.

Answer:

1. working on several tasks all at the same time
2. delete something, change your mind and use undo, then change your mind and use Redo to delete again
