Answer:
I believe the answer is C. It details the factors that are usually not included when thinking through the mind game.
Explanation:
This is because, the mind game is the idea that a person could go straight through the earth. Paragraph 6 further develops this idea by stating just how unrealistic the mind game is. Going straight through the earth is unjustifiable by any source other than the unrealistic assumptions of scientists. The mind game doesn't consider the aspects of tunneling straight through the earth such as, the rotation of earth, density of the different layers, and the friction from wind once this hypothetical tunnel is finished.
Other than that A and D don't make any sense to me as the answer. B, although a possible answer, I don't think is right because paragraph 6 is playing into the mind game, not saying it is pointless. Paragraph 6 adds more details that aren't usually considered or listed.
(I have not read through the book/article that addresses all of these matters, nor have I taken a class specifically for the writing containing these paragraphs. But, with the context given I believe this is the answer.)
