text: If the author has told a fact they have had soemthing to support it. The author says a lot about the things we can't do with Venus and has something to explain why with it. The author had a lot of facts and examples to help him support his and NASA's facts and ideas. I really like that the author will also give statistics because that is a huge way to support a fact or claim. Overall in this whole passage the author supports all ideas. TEACHER_NAME
