The author describes the high moral lessons learned from Greek mythology and how epics can instill key values in readers. Greek mythology was also rife with sexual encounters and dirty human actions. The author conveys strictly positive characteristics about epics and their utility. Clearly, the author’s account is idealistic. Choice "idealistic" is the best. Because the author is neither pessimistic (choice "pessimistic") nor doubtful, or dubious (choice "dubious"), one can then look at choice "idealistic". "critical" and "mysterious". The author does not really criticize Greek mythology; in fact, the author praises it. Also, the author’s account, or description, of Greek mythology is not mysterious; although, the actual mythology may very well be mysterious. Only choice "idealistic", idealistic, captures the sentiment attached to the author’s account of Greek mythology.
The answer is "attempt a description of a phenomenon", because in the passage they author starts to describe what a phenomenon.
The answer is I only, because it says in the passage that happens. So ‘I only’ is the best possible answer.
The passage begins by introducing swimming, narrowing it down to competitive sports and then expanding the concept to figure out what swimming will turn into in the future. Choice "An activity narrowed to a specific purpose and expanded to consider future implications" and choice "An activity narrowed to a specific purpose and expanded to consider future deviations." are close in meaning, but choice "An activity narrowed to a specific purpose and expanded to consider future implications." refers to implications, or effects, rather than deviations, or different versions resulting from changes. This minor change separates the two choices and makes choice "An activity narrowed to a specific purpose and expanded to consider future deviations." superior. Choice "An activity and its purposes are explained." is relevant, but it does not include the entire scope of the passage. Choice "A supposition regarding the prospect of an activity, analyzed for viability" only focuses on the conclusion and stretches beyond what the passage actually accomplishes. Choice "An activity narrowed to a specific purpose and expanded to consider future deviations." is best.
This question refers you to the conclusion sentence. The author states clearly that swimming must either progress into a new form or regress to the primal mode of movement. Choice "Swimming remains a competitive Olympic sport." and choice "People swim in home and community pools to relax and exercise." can be eliminated because they show no change, just a continuation of current circumstances. Choice "Humans settling on the moon use swimming techniques to move through space." is an actual possibility as humans may very well be settling in outer space in the future. Choice "Animals, including amphibians, begin to swim instinctively upon birth, as a dominant genetic trait." and "Fish begin swimming at unprecedented speeds and extend the average life span." refer to animals anyway, when the author specifically was predicting a future for humans. Choice "Humans settling on the moon use swimming techniques to move through space." is the most realistic and relevant prophecy according to the premises developed by the author.
