Question

tyler presented an informative presentation on earthquakes. he described the structural causes of earthquakes, how they develop, which areas of the earth are more prone to quakes, how quakes are measured, and what to do when one hits. the presentation exceeded the time limit and the audiences attention declined. from this description, what was tylers mistake?
failing to look at his audience
failing to conduct adequate research
failing to deliver the presentation in an interesting manner
failing to narrow the topic

Explanation:

Tyler covered many aspects of earthquakes like causes, development, measurement, etc. This made the presentation broad and likely led to exceeding the time - limit and audience losing attention. Narrowing the topic would have helped. There's no mention of not looking at the audience, inadequate research, or uninteresting delivery style.

Answer:

Failing to narrow the topic
