Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The author states that the value of returning to Venus is indesputable, yet horribly dangerous. Danger should not put off scientists into further discovering that planet, but rather it should encourage them to work even harder in order to someday provide a safe passage between Earth and Venus. This would be beneficial to human society, because it could potentially help rid future problems of overpopulation and even provide insight on what Earth may become.
