Rate the following argument fragment on its writing, argument, and language skills:

His solution to survive this weather that is dangerous to us humans is to allow them to float above the fray. A "blimp-like" vehicle hovering 30 or so miles would help avoid the unfriendly ground conditions . At thirty-plus miles above the surface, temperatures would still be toasty at around 170 degrees Fahrenheit, but the air pressure would be close to that of sea level on Earth
