Which of the following best describes a competition that persists over time without resolution?

The best description of a competition that persists over time without resolution is continuous rivalry. This term encompasses ongoing engagements between competing parties, indicating that the competition is not only consistent but also enduring, without a clear end or resolution in sight. This can be applied in various contexts, such as in business markets, sports, or geopolitical relations, where entities consistently strive to outperform one another over an extended period.

Dynamic equilibrium refers to a balanced state where competing forces are present, but they do not necessarily imply ongoing rivalry. In contrast, temporary conflict suggests that the competition is short-lived and likely to resolve itself, which does not align with the idea of persistent rivalry. Lastly, seasonal competition implies that the competition occurs at specific times or events, rather than being an ongoing, unresolvable rivalry.

Therefore, when capturing the essence of a long-term competition that continues without resolution, continuous rivalry is the most fitting description.
