Rate the following argument fragment on its writing, argument, and language skills:
Evidence: They are considering a blimp-like vehicle that would float above the suface of Venus to meet the challenges presented. This blimp would avoid the poor conditions of the Venusian landscape by floating some thirty miles above the surface. Conditions around the blimp would still be slightly hot, but the pressure and toxicity would be similar to that on Earth. These conditions are not ideal, but they would be sufficient enough to study Venus further. Another one of NASA's ideas is to use mechanical computers to study Venus. These mechanical computers do not require electronics, and they would be more resistant to the poor conditions of the surface. These new innovations in the study of Venus is what makes the dangers tolerable and the study worthy.
