Arthur keeps a flower vase on the table. He views it through a glass window, and the vase appears the same. When Arthur views the vase through baking parchment paper, he can observe the general shape of the vase, but it appears blurred.

What can best explain the blurring of the vase?

• light is absorbed by the opaque parchment paper

• light is reflected by the opaque parchment paper

• light is refracted by the transparent parchment paper

• light is scattered by the translucent parchment paper
