Swimming has developed from a primal mode of movement to an advanced hobby and competitive sport. Exercising nearly every muscle group, swimming is a rigorous sport and requires intense training. In competitions swimmers typically contend for the fastest time to complete a certain distance by performing a specific swimming stroke. Also, swimmers work to build endurance and an ability to swim over long distances. Because swimming has developed into a highly intricate competitive sport, where one wrong technique can disqualify a participant, it is interesting to ponder how the sport will evolve for people in the future, either advancing into a progressive purpose or regressing to a primal mode of movement. The structure of this passage could be best described in what way?
A. an activity narrowed to a specific purpose and expanded to consider future implications
B. an activity narrowed to a specific purpose and expanded to consider future deviations
C. a hypothesis tested against certain conditions, developed into a larger thesis
D. a supposition regarding the prospect of an activity, analyzed for viability
The paragraph begins by describing swimming and its evolution from a primal mode of movement to its development into an intricate competitive sport. The paragraph then expands to consider future deviations of whether swimming will advance into a progressive purpose or regressing to a primal mode of movement.
Therefore, the Correct Answer is B.
