Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Venus has been a challenging planet for humans to study, despite its proximity. The thick atmosphere of almost 97 percent carbon dioxide and highly corrosive sulfuric acid makes it difficult for spacecrafts to land on the planet. Scientist can't find out what they need to know about the planet. They want to know if there's a way to support life due to finding that Venus was probably covered with large oceans and could have supported life once. Today Venus still has some features such as valleys, mountains, and craters.
