Hypothetical in my opinion because their not meaning it literally
1-The Native Americans were on edge and did not know what to think of the Spaniards
2- The barge sinks while trying to leave the island
3- They become desperate for survival and the natives take them in and make them medicine men
4- The native Americans insist the Spaniards heal their men, but the Spaniards think its naive and will not work.
5- Making incisions over the wound, sucking on it, then cauterizing it.
Hope these answers help!
I would imagine "a comfortable amount of eye contact" would be a sign that you are confident, so that can be crossed out of the list.
"Business attire" gives off a professional vibe, which means if you happen to wear business attire, you're most likely serious about your topic and are confident about it, so that's also false.
Slouching could mean that you are not confident. When talking, you should stand straight up, slouching could give your audience the impression that you weren't well prepared for your topic or you're not confident about it.
So your answer should be "slouching" :)
