What of the following topics is too broad for a 10-minute speech?

A topic that is too broad for a 10-minute speech would be something like "The History of Human Civilization." This subject encompasses thousands of years, multiple cultures, and numerous significant events, making it impossible to cover effectively in such a short time. Instead, a more focused topic, such as "The Impact of the Renaissance on Modern Science," would allow for a more in-depth exploration within the time limit.
