Question

1. why would you change the power state of your computer?

to prevent your computer from overheating
to save batter power
to prevent others from watching your monitor

1. select the correct power states:

start, sleep, shut down
start, shut down, wake, and sleep
start, run, sleep, shut down
start, run, shut down

Explanation:

1. Changing the power state to sleep or hibernate saves battery power. Overheating prevention is usually handled by cooling systems, and preventing others from watching the monitor is more about privacy settings (like locking the screen) rather than power - state changes.
2. The common power states of a computer are Start (booting up), Sleep (low - power state where the computer can be quickly resumed), and Shut down (completely powering off). "Wake" is an action to get out of sleep, not a power state. "Run" is not a standard power state term in this context.

Answer:

1. to save batter power
2. Start, Sleep, Shut down
