Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The author is for the exploration of Venus, but consistently chooses to bring up the problems that doing so faces. The author writes about the difficulties about exploring Venus, because of the planet's extreme environment. They opposed their own side in paragraph three by saying, "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." This is an affective strategy, because people who may oppose exploration to Venus may say something similar to this. The author is arguing their own point to establish reliability and trust amongst with people who favor not exploring Venus. The author showing that they see the problems with exploring Venus shows that they are open minded and open to their mind being changed, and this will in turn have the reader do the same.
