Question 2

ANS: C
Oxygen in itself is a very reactive element. It binds quickly to other materials. Remember, free oxygen
only became abundant in our atmosphere when photosynthetic organisms began producing more.
Thus, if there is a large amount of free oxygen, then there is something present that is replacing it in
the atmosphere. This is likely to be a life-form of some sort. Information can be found in the section

Answer to Question 1

ANS: B
Laws provide explanations to events that occur in nature which are uniform when tested under the
same conditional parameters. Therefore, a law is able to summarize observations. A theory is actually
responsible for supplying explanations for those observations. Information can be found in the section
Marine Scientists Use the Logic of Science to Study the Ocean.
