Rate the following argument fragment on its writing, argument, and language skills:
Evidence: In the passages the author states, 25 years ago NASA's Viking 1 spacecraft was circling Mars snapping pictures looking for Viking 2, when it spotted the human face 2 miles big staring back at the camera. The author also says, "huge rock formation... which resembles a human head... formed by shadows giving the illusion of eyes, nose, and mouth."
