Answer:
The answers are C and D are the correct answer.
Step-by-step explanation:
Moon Speech - Rice University was addressed on September 12, 1962. The official name was Address at Rice University on the Nation's Space Effort, and president John F. Kennedy delivered it.
Letter C is correct because the speaker mentions that it is necessary to do something, and it also indicates how it should be done (boldly;) it is also mentioned that it is necessary to achieve the goal soon.
Letter D is also correct; as seen at the end of that phrase, the speaker mentions a future action when he says and we're going to climb. It is necessary to mention that the speaker uses the first person of plural we in both cases, to indicate that he is part of a group.
