3 multiple choice 2 points
what is the first thing you should check if your computer wont turn on?
if the mouse is working
the sound settings
if the computer is plugged in or has enough battery
the wi-fi connection

Explanation:

• Question 1: Pressing Ctrl + Alt + Delete is a common way to handle a frozen screen as it allows closing unresponsive programs. Turning up the sound, waiting for it to unfreeze on its own (which may not happen), or unplugging mouse/keyboard (won't fix the frozen state) are not effective solutions.
• Question 2: Deleting unnecessary files and uninstalling unused programs directly frees up disk space. Changing wallpaper, updating antivirus (which may free up some space minimally but not the main way), or cleaning keyboard (no impact on disk space) are incorrect.
• Question 3: If a computer won't turn on, first check the power source (plugged in or battery). Checking mouse, sound settings, or Wi - Fi (which are relevant when the computer is on) are not the first steps.

Answer:

1. Press Ctrl + Alt + Delete to open a menu and close unresponsive programs
2. By deleting unnecessary files and uninstalling unused programs
3. If the computer is plugged in or has enough battery
