If you are building a triad whose root is located on a line on the staff, where will the third and the fifth be located
a. on lines
b. on spaces
c. the third will be on a line and the fifth on the space
d. not enough info to tell

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.
