text: However, despite all of these challenges the come with exploring Venus, the author still claims that learning more about the second planet in the solar system has its own benefits. In the fourth paragraph, the unknown author explains that Venus has many similar features with Earth. He claims that many astronomers are "fascinated by Venus because it may well once have been the most Earth-like planet in our solar system" ("The Challenge of Exploring Venus"). He provides similarities such as the similar ecosystems Venus may have supported and implies that Venus may have had a biodiverse world. The author communicated to the audience that even today Venus has many features that are similar to Earth, stating, "Today, Venus still has some features that are analogous to those on Earth" ("The Challenge of Exploring Venus"). The author uses his facts and evidence to explain that life forms may have existed on Venus long ago. While the author does not explicitly state it, he is implying that studying Venus may help scientists learn how people from today's world can reside on Earth's "twin". This relates to current news with scientists and researchers learning how to develop and maintain life forms on another one of Earth's neighboring planets, Mars. As Venus has had many similar characteristics with Earth, the audience may realize that in the near future, the human population may grow to a number where it is necessary to settle on different planets. The unknown author uses evidence to explain that studying the atmosphere, solar power, and radiation levels of Venus would be important to support life on it.
