Read an excerpt from Justice Sonia Sotomayor's New York University 2012
Commencement Address:
Finally, the last emotion I've experienced has been the joy
of engagement. It's a hackneyed statement, but life is not a
spectator sport. To squeeze from life its fullness, to be
happy in this world in the short period of time we are given,
to find meaning in life, you have to be active and giving
members of your communities. Neither your life nor the
world you live in just happens. You control the quality of
your lives and your communities. It is only in giving to
others that you can find meaning and satisfaction in what
you do
What does Sotomayor use to introduce her discussion on the joy of
engagement?
O A. A statement that happiness should not be a life goal
O B. A comparison of two people's lives
O C. A metaphor about getting involved
O D. A suggestion that life has to be spontaneous

Justice Sonia Sotomayor was conferred a Doctor of Law degree, honoris causa, by the NYU on May 16. And she gave her speech at the 180th Commencement held at the Yankee Stadium.

In this speech, she recounts how life is all about taking challenges and getting involved in them. She went on to express her happiness on being conferred the degree while at the same time, she felt grateful to those who had awarded her. She also used a metaphor to talk about how getting involved in life is one of the most interesting and intriguing things in life. Her statement that "life is not a spectator sport" shows her own dedication to getting involved in life's challenges and tackling whatever obstacles that may come in the way.

Thus, the correct answer is option C.
