Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The author backs up his or her point by saying how "Astronomers are fascinated by Venus because it may well once have been the most Earth-like planet in our solar system. Long ago, Venus was probably covered largely with oceans and could have supported various forms of life, just like Earth." The fact that at one time Venus might have been covered in water has convienced me that there is some sort of way to create life there. Not only does he or she mention how Venus might have once been covered in water, but also informs the audience that Venus has many Earth-like structures. Venus is made up of mountians, valleys, and craters.
