Question

review the third paragraph. not so lonely planet 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 with earth - like conditions may be common. scientists believe that there are more than one trillion undiscovered exoplanets in the galaxy. scientists recently discovered a cluster of planets with conditions that might support life. scientists recently determined that life is possible on gaseous planets.

Explanation:

The claim is about planets with Earth - like conditions being common. The discovery of a cluster of planets with life - supporting conditions implies the existence of multiple such planets, supporting the claim. The first option about the number of undiscovered exoplanets doesn't directly show Earth - like conditions are common. The third option about life on gaseous planets is not relevant to Earth - like conditions.

Answer:

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