The structure of this passage could be best described in what way?
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 A and choice B are close in meaning, but choice A refers to implications, or effects, rather than deviations, or different versions resulting from changes. This minor change separates the two choices and makes B superior. Choice D is relevant, but it does not include the entire scope of the passage. Choice E only focuses on the conclusion and stretches beyond what the passage actually accomplishes. Choice B is best.
