Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Venus has a temperature that humans can not survive in, 800 degrees Fahrenheit. Also on Venus the pressure is 90 times what humans experience on Earth. Humans have never experienced conditions as extreme as those on Venus: "Even a submarine accustomed to diving to the deepest parts of [the] oceans" would be crushed and the high temperatures "would liquefy many metals." Something that was made to be able to go withstand high pressures, like a submarine, would be crushed on Venus, and metals can withstand very high temperatures but on venus they would liqeufy. It is unsafe and humanly impossible for humans to try to explore the land of Venus when some of the best technology can not even withstand the climate of Venus.
