Concluding Statement: Clearly, the author has efficiently and convincingly supported the idea that studying Venus is a worthy pursuit despite the dangers it presents. By describing all the information about the existence of other life forms and the similarities to Earth that we could potentially learn from the study, the author proves how worthy Venus is to be discovered. The author also rebuttals one of the main concerns for traveling to the planet by explaining how plans are being developed to make travel and living conditions surviveable, safe, and efficient for both humans and machines.
