Answer:

Explanation:
key signatures are important because they tell how how to play the music. For instance, in the key of C, it has no sharps or flats so you play all white keys. In the key of D, you have two sharps which are C and E. instead of playing the white notes for them you'd play the black.
The note gets 1 1/2 beats. Being the only note, there would be 2 1/2 beats of rest
Everything is correct except for number 5, which has two prepositional phrases, "behind the door: and "for her friend."
