56. What is the difference between using "adjust level of audio (quick)" and "adjust level of wave file (permanent) to change the volume of the audio track?

These commands are found under the Audio menu | Edit Audio. The "quick audio adjust" just accesses the same setting that you get using the speaker icon (i.e. the soundcard's volume level). It doesn't affect the actual wave file. The permanent level adjust (in dB) actually affects the wave file itself.

If you set the quick adjust to zero and rendered your song to wave, the WAV file would still get rendered with a normal volume, but if you reduced the dB of it using the other command, it would be quiet.
