Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The author states that scientists figured it was just another Martian mesa when the face appeared. This shows that they have seen things like this before and they knew that it wasn't real, or alien like. Another example that the author proves is that Garvin said it reminded him of Middle Butte in the Snake River Plain of Idaho. The camera on board MGS had to peer through wispy clouds to see the face and perhaps alien markings were hidden by haze. Also NASA can be hidding information about the Face. But, you can see that the Face is formed by shadows, and not an alien haze.
