Question

part b
which example from the passage supports the answer to part a?
*now this is a choice which this country must make, and i am
confident that under the leadership of the space committees of
the congress, and the appropriating committees, that you will
consider the matter carefully,...\ (paragraph 3)
*space is open to us now; and our eagerness to share its meaning is
not governed by the efforts of others.\ (paragraph 1)
*recognizing the head start obtained by the soviets with their large
rocket engines, which gives them many months of lead - time, and
recognizing the likelihood that they will exploit this lead for some
time to come in still more impressive successes, we nevertheless
are required to make new efforts on our own.\ (paragraph 1)
they could in fact, aggravate them further—unless every scientist,
every engineer, every serviceman, every technician, contractor, and
civil servant gives his personal pledge that this nation will move
forward, with the full speed of freedom, in the exciting adventure of
space.\ (paragraph 6)

Explanation:

To solve this, we need to assume the answer to Part A (likely about US space efforts in response to Soviet advances). The third option talks about Soviet lead in rocket engines and US needing new efforts, which would support a Part A answer about US responding to Soviet space progress. The first is about Congress leadership, second about space being open, fourth about personal pledges—none match as well as the third.

Answer:

The third option: "Recognizing the head start obtained by the Soviets with their large rocket engines, which gives them many months of lead - time, and recognizing the likelihood that they will exploit this lead for some time to come in still more impressive successes, we nevertheless are required to make new efforts on our own."
