Context: The passage below describes an experiment. Read the passage and then follow the instructions below.

Martha poured four ounces of water into each of six glasses. Martha dissolved one tablespoon of salt in each of three glasses, and did not add salt to the other three. Then, Martha placed an egg in one glass and observed if the egg floated. She removed the egg and dried it.
