Both the reading and listening parts offer two opposite views about the possibility of a permanent station on Venus. While the passage lists three main problems for a human presence on Venus surface, the lecturer, on the other hand, purposed a floating station in fifty kilometers above Venus surface in the atmosphere to overcome these problems.
First of all, the text mentioned to the high atmospheric pressure at Venus's surface, which is 90 times greater than on Earth's surface, as one of the main issues that halt the presence. On the other hand, the professor, claims that since by the increment of height the atmospheric pressure decreases, at the 50 kilometers above the Venus surface, the atmospheric pressure is equal to the atmospheric pressure on Earth surface. Consequently, the floating station can be a feasible solution for a human presence on Venus.
Secondly, the article highlights the impracticality of importing the oxygen and water from Earth, since Venus does possess no reservoirs for water and oxygen, as the second problem of living in Venus. On the contrary, the instructor said that as Venus mostly made up carbon dioxide and sulfuric acid, the chemical reaction by the sulfuric acid and carbon dioxide can be considered as the consistent supply for the water and oxygen production in Venus. Therefore, there is no concern about the water and oxygen regular supply from Earth, as Venus is independent for their production.
Finally, meanwhile, the passage bolded the little sunlight which reaches Venus surface as another issue living on Venus; the lecturer refutes this factor too. As he explains, the height of fifty kilometers above the surface causes more sunlight reaches the station. Furthermore, the solar power cells at this height have this chance to receive all the direct and reflected sunlight from the clouds, as the station is close to those clouds. Thus, the station, at this level, can reach sufficient sunlight to make the electricity.
