Rate the following argument fragment on its writing, argument, and language skills:
Evidence: NASA's advancements for Venus exploration are promising, "For example, some simplified electronics made of silicon carbide have been tested in a chamber simulating the chaos of Venus's surface and have lasted for three weeks in such chaos," (7). Humans would not be able to use the most advanced technology, but durability is the goal, "By comparison, systems (mechanical computers that use gears and levers to calculate) that use mechanical parts can be made more resistant to pressure, heat, and other forces," (7). If humans were to only hover over Venus, the possibilites are limited. Humans and technology have to be as close as possible. Technology that could last for a few weeks is enough to vastly expand our knowledge. Mechanical computers are now obsolete, but in Venus would be a valuable tool, just like the other electonics being made. Researchers have worked tirelessly to continue making Venus exploration a reasonable reality.
