Question

select the two supporting claims that the author makes to argue that sending humans to mars is a wise move for the advancement and ultimate survival of humanity. mars may contain substances that could enhance life for humans on earth. settling on mars helps to solve the problem of earth’s overpopulation. getting many nations on earth to work toward one goal will promote peace.

Explanation:

To solve this, we analyze each claim:

1. "Mars may contain substances that could enhance life for humans on Earth": This supports the idea that sending humans to Mars is wise for advancement/survival, as finding beneficial substances would help humanity.
2. "Settling on Mars helps to solve the problem of Earth’s overpopulation": Reducing Earth’s overpopulation aids human survival, so this supports the argument.
3. "Getting many nations on Earth to work toward one goal will promote peace": While peace is good, it does not directly relate to "advancement and ultimate survival of humanity" as the other two do (focuses on peace, not survival/advancement via Mars mission).

So the two supporting claims are:

• Mars may contain substances that could enhance life for humans on Earth.
• Settling on Mars helps to solve the problem of Earth’s overpopulation.
