Question

which statement best describes the central idea of the section how will nasa use rockets in the future?
a. nasa is developing new rockets that will look like earlier rockets.
b. rockets are being developed to be able to take supplies into space.
c. new rockets will be able to handle heavy cargo and explore further into space.
d. humans will someday be able to travel to mars.

Explanation:

To find the best central idea for the section "How Will NASA Use Rockets in the Future?", we analyze each option:

• Option A: The focus of future rocket development is not on looking like earlier rockets, so this is incorrect.
• Option B: While taking supplies to space is a use, it is too narrow. Future rockets likely have broader goals.
• Option C: New rockets being developed by NASA for the future would aim to handle heavy cargo (for missions) and explore further (like deeper space, Mars, etc.), which captures the broader central idea of future rocket capabilities.
• Option D: Travel to Mars is a specific future goal, but the section's title is about how NASA will use rockets in general, not just Mars travel. This is too specific.

Answer:

C. New rockets will be able to handle heavy cargo and explore further into space.
