Exercise 3 Draw a line under the thesis statement in the paragraph below. Replace it with a new thesis statement that clarifies the writer's theme.
Starfish are marine invertebrates. Sometimes sea waves roll rocks on top of the starfish,
damaging an arm. In other cases, the starfish sheds an arm if it is attacked by a predator. The
starfish sacrifices the arm as a way of escaping from the predator. As the new arm grows to full
size, which takes several weeks, the other arms are used for Icoding and moving.
