Answer:
1. Narrative
2. Emotional
3. Funny
Explanation:
One expectation of a best man's speech is "narration".
A typical audience would expect a best man to be a close and long time friend of the groom and most times the bride.
This would lead to the expectation that his speech should be narrative. That is, he should be able to speak about past events and circumstances experienced by the three of them.
A best man's speech is also expected to be emotional. A wedding is an emotional ceremony and a typical audience would expect any speech to be full of emotions to complement the already existing emotions in the atmosphere.
A wedding is not just about emotions but also an event where people come to celebrate, laugh and reconnect.
A typical audience would expect a best man's speech to be filled with humor so as to further lighten the mood of the audience.
