Rate the following argument fragment on its writing, argument, and language skills:
Lead: Venus, otherwise known as the "Evening Star," is one of the more challenging planets to examine closely in our solar system. While this plant is often called Earth's twin, it is vastly different in terms of environment and hospitability. Despite being the closest planet to Earth at times, no spaceship has touched down on Venus in over thirty years. The dangers presented by Venus are many, but the author greatly supports the idea that studying Venus is a worthy pursuit despite these dangers.
