text: I believe that the author does not support their opinion well in the passage. This is because they heavily focus on the negatives of exploring Venus, rather than the positives. For example, in paragraph 2, the author says, "Each previous mission was unmanned, and for good reason, since no spacecraft survived the landing for more than a few hours." Because the author included this, it automatically leaves the reader with a negative connotation towards the exploration of Venus. The author then continues to show more negatives of the exploration of Venus in the third paragraph. The author states, "These conditions are far more extreme than anything humans encounter on Earth; such an environment would crush even a submarine accustomed to diving to the deepest parts of our oceans and would liquefy many metals." Once again, this makes the reader think negatively about Venus. Since the author included this in the passage, it gives the reader another reason to think poorly of studying Venus.
