The correct answer is the option A)He draws on American’s patriotism and values to justify his goals to greatly expand the space program. In John F. Kennedy Moon Speech in Rice Stadium (1962), we can see a leader that seeks for knowledge and freedom in the hands of the United States, he wants the country to grow as a great nation with all the progress that comes with technology and space exploration. In this speech, we can see that he appeals to be the number one and that's a very patriotic idea, he compares to other nation's like the Soviet Union, not in a bad way but to prove that they are going to be the best in space technologies as they conquer the moon and beyond. He always talks about seeking knowledge by American man because they are good for all the people, they have good values and that justify the expansion of the space program in the United States.
So it's not the option B because he is not regardless of the potential consequences for others, he believes that all the progress from the United States will be good for all mankind. It's not the option C as he doesn't focus on fears and then discourage them for placing importance on space exploration, he is the one who encourages them to explore and grow more in that field. And finally is not the option D as he doesn't talk about disrupting the Soviets progress in space, He wants American people to be better and better means good for all.
Here you have a phrase of John F. Kennedy speech (1962) that will resume the content of the speech that proves why A is the correct answer: "We mean to be a part of it--we mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace".
