Question

Quizplus · Accepted Answer

Scientists have focused their search for life outside of Earth on Mars due to its proximity to Earth and the possibility of liquid water existing on its surface in the past. Multiple missions, including the recently launched Perseverance rover, have been sent to Mars to search for signs of past or present life.

Answer: E
 Scientists have also begun searching for life on Titan, one of Saturn's moons. While not a typical candidate for life due to its extremely cold temperatures and lack of liquid water, Titan has organic molecules, which are the building blocks of life, and a liquid methane-based cycle that has led some scientists to hypothesize the existence of exotic types of life on its surface or subsurface ocean.
