Next, the lecturer claims that water and oxygen can be produced with the compound of the Venus. The chemical materials, sulfuric acid and carbon dioxide are easily obtained through the atmosphere of the Venus. This refutes the point made in the reading passage that the absence of water and oxygen make human presence impossible.

Second, the professor suggests the way to formulate water and oxygen. There are easily obtainable substances, such as Carbon Dioxide. By adopting this method, there would be no need to supply water and oxygen from the Earth. This challenges the reading passage that water and oxygen would not be available in the station so that permanent base in Venus is improbable.

The professor points out that there are mostly carbon dioxide and sulfuric acid in Venus’s atmosphere. But water and oxygen could be produced by using chemical elements out of these compounds which means that can easily obtain oxygen and water. On the other hand, the reading passage refutes the idea that the Venus’s atmosphere contains hardly any oxygen or water vapor.

Second, the lecturer believes that it’s possible to supply water and oxygen in Venus. Though Venus is composed of carbon dioxide and other compounds, by using technical process, water and oxygen can obtained easily. Therefore the idea that regular supply of water and oxygen is impossible presented in reading material can be disputed.

The professor insists that people can make water and oxygen by using the compound such as carbon dioxide and sulfuric acid which are easily obtained from the atmosphere. By using this method, people will able to make water and oxygen. And this refutes the point made in the reading passage that water and oxygen would therefore probably have to be supplied to Venus from Earth.

Second, the professor insists that we can make water as compound materials that are included in the Venus. But this refutes the point made in the reading passage that there are not reservoirs for water in Venus so human can not live in the planet.

Second, the lecturer says that water and oxygen can be made from the carbon compounds at the atmosphere of Venus. By using chemical process, the substances may be used to create water and oxygen that are needed for survival on Venus. And this is against the point made in the reading passage that water and oxygen have to be supplied from Earth.

The professor claims that we can get water and oxygen from compounds of carbon dioxide and nitrogen by chemical process. We need water and Oxygen to survive on Venus and by using this method, we can get water and Oxygen easily .
