Rate the following argument fragment on its writing, argument, and language skills:
Lead: A planet that has enough heat and pressure to melt most metals and crush any submarine may not sound like an ideal location to visit, but scientists at NASA are determined on researching it because even though it has horribly immense climate, it may be the closest planet in our solar system to Earth. The article "The Challenge of Exploring Venus," the author speaks of how scientists strongly believe that learning more about Venus can lead to answers about the creation of Earth. It is an extremely difficult task to accomplish, as most rovers NASA has sent there have not lasted more than a mere few hours. In order to research the planet in depth, NASA would need to send living humans to Venus, however, this will be rediculously challenging and even more so dangerous.
