Question

sending humans to mars offers the opportunity to explore the unknown, much like the travel and research conducted in the deep sea. materials from deep - sea marine organisms are currently being used or developed to battle inflammation, fungal infections, tuberculosis, hiv, and cancer. there is reason to believe mars is also home to matter with the potential to help humans. photographic evidence from nasas mars reconnaissance orbiter shows the possible presence of ancient deep - sea thermal vents, just like the ones on earth, where some scientists believe life on our planet originated. researchers have examined photos and determined that the area contains a mix of minerals that could serve as a source of energy for life forms. if microbial life exists on mars, it could assist with medical advancements like select the evidence that the author provides for the following supporting claim: mars may contain substances that could enhance life for humans on earth. the pictures taken by robots currently stationed on mars show the fossils of deep - sea organisms that could help cure diseases. blurry photographs of marss topography led to a breakthrough discovery unrelated to the mars mission. photos indicate that mars has ancient deep - sea thermal vents, so maybe it possesses biological materials that are useful to humans.

Explanation:

The text mentions that photographic evidence from NASA's Mars Reconnaissance Orbiter shows possible ancient deep - sea thermal vents on Mars like those on Earth where life originated, and that if microbial life exists on Mars, it could assist with medical advancements. The third option aligns with this reasoning as it points out that the presence of ancient deep - sea thermal vents on Mars implies it may have useful biological materials. The first option is incorrect as there is no mention of robots on Mars showing fossils of deep - sea organisms. The second option is about a discovery unrelated to the Mars mission's goal of finding substances to enhance human life.

Answer:

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