to dim the monitor display; a dim monitor is better for users eyes
to keep computers from wearing out too quickly
to give users something to do trying to wake up the computer
to save battery life and to save energy

1. how do you organize files, pictures, or songs?

files
ram
folders
desktop

Explanation:

For question 3: Power states in computers are mainly about energy - related aspects. Dimming the monitor (while it may have some eye - care aspect) is not the main reason for power states. Keeping computers from wearing out too quickly is not the core function of power states. Giving users something to do (waking up the computer) is a side - effect, not the purpose. Saving battery life and energy is a fundamental reason for power states.
For question 4: Files are what we organize (not how we organize). RAM is a type of memory, not a way to organize data. The desktop is a visual interface, not a way to organize. Folders are used to group and organize files, pictures, or songs.

Answer:

1. to save battery life and to save energy
2. folders
