Rate the following argument fragment on its writing, argument, and language skills:
Evidence: One of the points brought up was "Venus was probably covered largely with oceans and could have supported various forms of life,just like Earth". The author uses the word "probably" which means that he doesn't know this to be a fact or not. The author also wrote "Astronomers are fascinated by Venus" ; this is an opinion, seeing as some astronomers might heavily dislike venus. A good informative or arguementative essay provides facts to supports its ideas, rather than just guessing or presuming.
