Answer

Brief Explanations:

Kinetic energy is energy of motion. When Ellen started pedaling and moving along the street, her state changed from being stationary to moving, indicating a change in kinetic energy. Just getting on the bike and having feet off - ground doesn't show a change in motion - related energy.

Answer:

When Ellen started pedaling her bike, she began moving along the street.
