In an informal presentation where Elias wants to support his point about the family visiting a beach on a previous vacation, he could use different types of evidence. Here are the types of evidence he could consider:
1. **Analogical evidence**: Elias could use analogical evidence to compare the beach they visited to something similar he is presenting. This could help the audience understand the setting and atmosphere of the beach they visited.
2. **Anecdotal evidence**: Elias could use anecdotal evidence by sharing personal experiences about their previous beach vacation. This personal touch can make the presentation more engaging and relatable to the audience.
3. **Testimonial evidence**: Elias, as a credible expert on the beach and his family vacations, could provide testimonial evidence. By sharing his expertise and experiences, he can enhance the credibility of his point about the family visiting the beach.
Each of these types of evidence can enrich Elias's presentation and make his point about the family's visit to the beach more convincing and compelling.
