The function of this place is to encourage the enjoyment of art through direct interaction with works of art. A. museum
B. art criticism
C. crayon
D engraving

Explanation:

C and D are tools. I'm not sure they should be the answer. The best answer is B. The visitors to an art museum get to see actual works of art and not just a picture of it. No photograph can fully convey the artists intent.

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.
