text: The author uses facts that does not fit his opinion on why we should try to put a man on Venus. He actually uses more reason why we should not put a man on Venus. The author uses the other side of the arguements evidence that he is against as evidence which he should not do. " Each previous mission was unmanned, and for good reason, since no spacecraft survived the landing for more than a few hours. Maybe this issue explains why not a single spaceship has touched down on venus in more than three decades" (paragraph 2). This shows how the author was saying reasons why we should not try to get a man on venus.
