Hello. You did not submit the texts to which the question refers. The texts are:
#1 The Case for Mars By: Alexander Fisher
#2 Mars—A Waste of Time and Money By: Juniper Springs
Answer and Explanation:
1. The authors had opposing views. While Fisher considers exploration and Mars to be a positive thing that will benefit humanity, Springs believes that exploration is a waste of money and that it is very dangerous for humans.
2. The authors use the same point of comparison, since both discuss in their arguments, the atmosphere of Mars, the technology used, the limitation of robots and the possibility of using Mars to escape from the problems of the earth.
3. The authors present support their points of view in different ways, as one shows positive evidence about the exploration of Mars, while the other shows negative evidence. An example of this can be seen when Fisher says that exploration of Mars could promote wonderful technological elements for humanity, while Springs says that exploration will be a waste of money and that this money should be used to solve problems that the earth presents.
4. Both focus more on logical appeals, although they present some moments of emotional appeals, especially Springs' text, which tries to stimulate a certain dread of Mars exploration.
