Rey presented an informative speech on earthquakes. He described the structural causes of earthquakes, how they develop, which areas of the earth are prone to quakes, how quakes are measured, the damage they do, and what to do when one hits. The speech became dry, the audience's attention declined, and it exceeded the time limit by almost twice the amount of time. From this description, what was Rey's mistake?

Failed to limit his topic

Explanation:

Every speech has certain limit of words that should be presented in form of audience as per time constraint.It is preferred that speech should cover the required content , subject and issue by providing information but also maintain time and word limit.Exceed time, giving length speech , too-short speech etc can distract attention of audience and create boredom.

According to the question,Rey failed to narrow the speech to certain limit,.He did explain content and every topic in audience but exceeded time limit as well as topic limit.Thus,audience lost interest in his speech.
