Question

3 earth - like planets are more common than most people may realize. for a planet to be considered similar to earth, it must be rocky, rather than gaseous. rocky planets are seen as more likely than gaseous planets to support life. in addition, it must occupy the so - called temperate zone, which is the distance from the sun where liquid water is possible. exoplanets that satisfy these conditions are being discovered all the time. for example, in early 2017, the scientific community was rocked when a cluster of planets that resemble earth was discovered. named trappist - 1, the solar system consists of seven rocky exoplanets that orbit around a nearby star. at least three of the planets sit within the temperate zone, which means they may house oceans of liquid water. \of all the planets weve found, this system has
select the evidence that the author provides for the following supporting claim: planets with earth - like conditions may be common.
scientists recently determined that life is possible on gaseous planets.
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.

Explanation:

1. Analyze the first option: The paragraph states rocky planets are more likely to support life than gaseous ones, so this option contradicts the text.
2. Analyze the second option: The paragraph focuses on Earth - like planets and their discovery, not the number of undiscovered exoplanets in general, so this is not relevant.
3. Analyze the third option: The paragraph gives the example of TRAPPIST - 1, a cluster of planets with Earth - like conditions (rocky, in temperate zone) that was discovered, which supports the claim that Earth - like planets may be common.

Answer:

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