At age 10 you carved your name into the trunk of a 20 ft oak tree at about chest-height (for your 10-yr-old self). Thirty years later you are back in your hometown and visit the park where this tree was growing. Your tree is still there! Choose all of the following that should be true.
a. The tree ceased to grow at the point where you carved.
b. The tree is taller
c. The trunk where you carved your name is wider.
d. The place where you carved is no longer at chest height- it is up higher on the trunk than it was before.
e. Looking at the tree, you can see how tall you were when you were ten years old.
