Does the photograph show a pond or a lake?
Look for plants.
Plants can grow in ponds but not in lakes.
In ponds, plants grow both under and on top of the water.
But plants can’t grow in deep water.
So plants can only grow near the edge of lakes.
In the middle, the bottom of the lake is too dark.
Look at the title and picture.
What is the reading about?
a. Places outside b. Places inside
