Complete Question Explanation
Flaw in the Reasoning. The correct answer choice is (A).
The author tells us that it is possible, albeit expensive, to build moon colonies, and that the population is growing and we are running out of space on Earth. This gives us an incentive to build those colonies, and the author then concludes that we will therefore almost certainly build them someday. A good abstraction of this argument would be "We can do X, and there is a reason to do X, so we will probably do X."
When put that way, the flaw should be clear: being able to do something and having a reason to do it does not necessarily mean that we will actually do it. Perhaps there will always be more reasons NOT to do it than to do it? Look for an answer that points out that the author has failed to consider the relative strength of the reasons for building moon colonies vs the strength of the reasons for not building them.
Answer choice (A): This is the correct answer choice. This answer captures the author's failure to consider the relative strength of the reasons for and against building moon colonies. Even with the incentive to build them growing, it could be that the reasons against building them will always outweigh the reasons for doing so.
Answer choice (B): The argument does NOT assume that building moon colonies will be the only solution to the overcrowding problem, but only that the reasons for doing so will be more persuasive than the reasons for not doing so. Correct flaw answers must describe something that actually happened in the argument, and the author never went to such an extreme as to imply this was the only option. One further argument against this potentially attractive answer is found in the conclusion, where the author said "almost certainly" rather than "certainly."
Answer choice (C): This answer describes something that did NOT happen in the stimulus! The author did not toverlook the possibility that moon colonies would be built - the author said that they would be!
Answer choice (D): While the argument never addressed the possibility described in this answer choice, and so it could be said that they overlooked this, this would not constitute a flaw of the argument because the author is only claiming that it is likely that such colonies will be built, and not that doing so would be a complete and perfect solution to the overcrowding problem.
Answer choice (E): The argument has nothing to do with what humans would prefer, and it would not be a problem for this author if some people would like to live on the moon even if Earth was not overcrowded. The author did not take such a possibility for granted because it would not matter either way.
