Note this is based on elements available in the fan vote (https://www.survivor50cbs.votenow.tv/) and will be updated as new items are added.
Will resolve during the airing of Survivor 50: results being released doesn't count, we have to see it on the screens, in case the producers change their mind.
Resolution notes and clarifications:
Final four fire making refers to the current format of the final four immunity winner selecting someone to come into the final three and the other two make fire. An ordinary final four vote ending in a 2-2 tie which then goes to fire making tiebreaker will resolve "NO"
I will need clarification on the rice but whatever the vote is: I'm guessing it's tribes are given rice at the start of the game (YES). It's definitely not whether we see rice at all during the season.
