Answer to Question 1

ANS: C
Not all red giants are large enough to become a supernova. When our sun begins to die, it likely will
not become a supernova. It will engulf planets and expand its radius. The pieces sent into space are to
be recycled. Information can be found in the section What Will be the Future of Earth.

Answer to Question 2

ANS: B
The simplification of an observation in nature or in a laboratory is conducted by manipulating
conditions. Often times, one aspect is manipulated at a time to narrow possible reasons for an
observation. Information can be found in the section Marine Scientists Use the Logic of Science to
Study the Ocean.
