Trivia... sudoku
Puzzling Asked on May 27, 2021
An entry in Fortnightly Topic Challenge #49: Pub Quiz Camouflage
Please do not search the answers online (hence the no-computers tag), otherwise it would be too simple to solve this puzzle. I tried to recreate the team-play spirit of the pub quiz challenges by designing this puzzle such that it is possible for different people to answer different questions. So I would rather prefer a community-wiki answers with a lot of contributors than an answer with the solution found online.
You need to fill the grid by answering the questions below and by applying the normal sudoku rules.
Each table R1-R9 corresponds to a row of the sudoku. For each table, match each element from the first column (C1-C9) to the correct number in the second column or in the images (1-9). Then write that number in the corresponding cell. For example, if you think that Gregor Mendel was born in 1933, write 5 in R1C3.
