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 evidence that the author provides for the following supporting claim: planets earth - like conditions may be common.
scientists recently discovered a cluster of planets with conditions that might support life.
scientists recently determined that life is possible on gaseous planets.
scientists believe that there are more than one trillion undiscovered exoplanets in the galaxy.

Explanation:

The supporting claim is that planets with Earth-like conditions may be common. The text cites evidence of water in the galaxy and the discovery of seven habitable, Earth-like exoplanets. The first option matches this by referencing a cluster of planets with life-supporting conditions, while the other options are not mentioned in the provided text.

Answer:

Scientists recently discovered a cluster of planets with conditions that might support life.
