Question

select the evidence that the author provides for the following supporting claim: mars may contain substances that could enhance life for humans on earth.
blurry photographs of marss topography led to a breakthrough discovery unrelated to the mars mission.
the pictures taken by robots currently stationed on mars show the fossils of deep - sea organisms that could help cure diseases.
photos indicate that mars has ancient deep - sea thermal vents, so maybe it possesses biological materials that are useful to humans.

Explanation:

To support the claim that Mars may contain substances enhancing human life, we analyze each option:

• The first option (blurry photos of Mars’ topography) is unrelated to life - enhancing substances.
• The second option (fossils of deep - sea organisms for curing diseases) is about Earth - based deep - sea organisms, not Mars.
• The third option (photos indicating Mars has ancient deep - sea thermal vents and maybe useful biological materials) directly links Mars to having materials useful to humans, which supports the claim.

Answer:

Photos indicate that Mars has ancient deep - sea thermal vents, so maybe it possesses biological materials that are useful to humans.
