Which of the following best describes a cycle?

• A. a series of events which repeat over time
• B. a bicycle
• C. an extended period of time
• D. a short loop in a computer program

Answer: (A)

A cycle is a series of events that repeat over time. This captures the idea of recurring patterns and phases, such as the seasons, the water cycle, or a life cycle, where the same steps or stages occur again in a regular sequence.

A bicycle is a physical device, not a description of repeating events. An extended period of time refers to duration, not repetition. A short loop in a computer program is a loop, a programming concept for repeating a set of instructions, which is related in idea but not the general sense of a repeating sequence over time.
