I know a few answers since I know just a tid-bit of guitar because i'm starting to learn. Good practice for me

Anyway, well ... here goes nothing. some might be wrong .. since i'm still kinda a beginner. You can decide if you wanna trust my answers or not, I'll only do ones i can do so ya.
1. 1 (well think so.... 1 is index, 2 middle, 3 ring, 4 pinky)
12. Tempo is the speed or pace of a given piece of music.
21: True or False: In tablature, a mute strum is written with an "x." True
38:If your strings are too far off the fret board, then your "action is too high." True (don't exactly get that one. but when it says action is too high means the string is to high above the frets aka. the ltitle rides on the neck)
41: Which of the following shows better finger positioning? B (in a the fingers are too flat meaning they could mute some strings by accident when playing chords)
