Read the paragraph from President Jimmy Carter’s speech “Energy and the National Goals—A Crisis of Confidence.”

I ask Congress to give me authority for mandatory conservation and for standby gasoline rationing. To further conserve energy, I’m proposing tonight an extra ten billion dollars over the next decade to strengthen our public transportation systems. And I’m asking you for your good and for your nation’s security to take no unnecessary trips, to use carpools or public transportation whenever you can, to park your car one extra day per week, to obey the speed limit, and to set your thermostats to save fuel. Every act of energy conservation like this is more than just common sense, I tell you it is an act of patriotism.

Which option mostaccurately describes why Carter’s words are likely to persuade his audience to act voluntarily to conserve energy?

Energy and the National Goals

because President Carter presents them with enough data and facts so that they can also appeal to Congress
because President Carter demonstrates his knowledge of the amount of energy wasted
because President Carter will ask Congress to establish mandatory conservation laws
because President Carter explains that change will start from the top, beginning with the government

I agree.
"act voluntarily " is not "mandatory"
