Which of the following indicates silence in musical rhythm?
a) quarter note
b) whole rest
c) middle c
d) 8th note

answer; i believe the correct answer is "he who gladly serves"

i would say the answer is b. zigzag lines of the leaves. i believe this is the answer because zigzag lines go in different direction while the other options like: the vertical lines of the trees, the dotted lines on the road, and the curved lines of the park benches go in one direction.
