I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "If there are differences within a growth ring, then the part of a growth ring nearest the center of the tree, and formed early in the growing season when growth is rapid, is usually composed of wider elements. It is usually lighter in color than that near the outer portion of the ring, and is known as earlywood or springwood. The outer portion formed later in the season is then known as the latewood or summerwood. However, there are major differences, depending on the kind of wood (see below)."?
The part of a given ring that is likely to be dark is called what?
