Question

not so lonely planet
1 are we alone? this question has weighed on the minds of humans for centuries. some have long claimed that alien life indeed exists both within earths solar system and beyond. still, conclusive proof of alien life has remained out of reach. recently, however, nasa scientists have given the world a reason to believe that the existence of alien life is not only possible, but probable. recent discoveries suggest that, beyond earth, the solar system is full of conditions that could support life as we know it. continuing evidence of water in other parts of the galaxy, as well as a recent breakthrough discovery of seven habitable exoplanets similar to earth, support the notion that finding alien life is a quickly approaching possibility.
select the two supporting claims that the author makes to argue that it is likely that alien life exists beyond earth.
findings of water on mars and europa have led to the discovery of past alien life.
watery conditions elsewhere in the solar system support the possibility of alien life.
planets with earth - like conditions may be common.

Explanation:

1. Analyze the first option: The passage says there's evidence of water but no discovery of past alien life, so this is incorrect.
2. Analyze the second option: The passage states "Continuing evidence of water in other parts of the galaxy" supports alien life possibility, so this is a supporting claim.
3. Analyze the third option: The passage mentions "a recent breakthrough discovery of seven habitable exoplanets similar to Earth", implying Earth - like planets (habitable, similar to Earth) may be common, so this is a supporting claim.

Answer:

B. Watery conditions elsewhere in the solar system support the possibility of alien life.
C. Planets with Earth - like conditions may be common.
