Which statement best describes the major technical focus for the butterfly stroke?

• A. Butterfly: symmetric arm pull and dolphin kick timing
• B. Freestyle: streamlined body and catch
• C. Backstroke: flat alignment and fingertip entry
• D. Breaststroke: arm pull timing with leg whip and glide

Answer: (A)

The main idea being tested is how butterfly relies on a coordinated, symmetrical arm pull with the dolphin kick to create propulsion and maintain rhythm. In butterfly, both arms work together in a single pull, pulling underwater in a strong, even pattern, while a powerful dolphin kick drives propulsion in phase with that arm cycle. Getting the timing right keeps the body in a compact, streamlined position, maximizes thrust, and minimizes drag. If the kick and pull aren’t synchronized, propulsion drops and the stroke becomes inefficient or unstable.

Other options point to aspects of different strokes: a freestyle emphasis on staying streamlined and achieving a strong catch; backstroke focus on maintaining flat alignment and fingertip entry; breaststroke emphasis on arm pull timing with the leg whip and glide. These describe features of those strokes, not the principal focus for butterfly.
