Question

rowing, also called crewing, involves several people propelling a slender boat, called a shell, through the water. in order to keep from entangling the oars of those in front of and behind them, the rowers must be synchronized. they must complete each step of each stroke in unison. this allows the rowers to maximize their energy output in propelling the shell forward. rowing, when done well, often looks like one continuous motion, performed as a team in perfect time. when done poorly, the shell can tilt, making it difficult for rowers to get their oars clear of the water. the boats motion through the water can become less fluid, too. in crewing, is crucial. rhythm viewpoint agility income

Explanation:

The text emphasizes that rowers must be synchronized and complete each stroke step in unison to maximize energy output and move the shell forward smoothly. Rhythm is related to this synchronization and timing.

A. rhythm
