text: The authors pros and cons list combat eash other because, the author gives a pro on the exploration of Venus but instantly combats it with another con to weigh it out. One example of this is in paragraph 5 when the author states that the conditions of floating above planet Venus would be difficult but survivable for humans. However, right after making that statement, the authors first sentence in paragraph 6, combats the idea that it is survivable for humans because the article states, "However, peering at Venus from a ship orbiting or hovering safely far above the planet can provide only limited insight on ground conditions because most forms of light cannot penetrate the dense atmosphere, rendering standard forms of photography and vidoeography ineffective." From that statement we can infer that the author doesn't really see the exploration of humans going being very useful but, we can only infer because the author never specifies, for or against.
