When explaining past explorations to Venus, the author states, "Long ago, Venus was probably covered largely with oceans and could have supported various forms of life, just like Earth." Facts that have been presented that occured in the past help the author support his idea that there is reasons why people should look into further studying Venus. These past facts present the idea that Venus once looked like Earth did, and if that is true, there are reasons why it should be looked into further. The passage later explains examples of NASA's approached to studying Venus when the author says, "Another project is looking back to an old technology called mechanical computers. These devices were first envisioned in the 1800s and played an important role in the 1940s during World War II." The idea of looking back on past resources to help the studying of Venus would help the process. This past project is a key tool that helps support that Venus should be studied even though it can be extremely dangerous. Using past experiences such as the ones included helps support and grow the authors idea.
