text: In paragraph four, the author states that, " Astronomers are fascinated by Venus because it may well have once been the most Earth-like planet in our solar system." (par. 4) the author then explains that the planet was probably covere in Earth-like features such as oceans. This could give us insight on what happened to Venus to change it into the toxic and empty wasteland that it has become and how something similar could happen on Earth, if we choose to explore the planet.
