Answer:
a startling statistic
Explanation:
According to my research on different presentation tactics, I can say that based on the information provided within the question Maurice seems to be using a startling statistic to open his presentations. This is a piece of factual information that is not known by those viewing the presentation and causes momentary fright, surprise, or astonishment. Which is what Maurice is doing by sharing the lesser-known facts to open the presentation.
