I really like the idea, thank you :-) I agree with Philippelebel that some of the answers are too close together - it kind of stops me caring whether I got it right or not, which takes away some of the fun (I'm not even sure whether I got JFK right or not and can't be bothered to check).
There were also four people who I'd either never heard of or know nothing about, but that's my problem I suppose!
Anne Frank and Emmet Till are guessable if you know about their life, which is good. There should be more like that (such as Joan of Arc).
Many others are just a crapshoot, like JFK: every one knows he was shot in his 40s or so, but all the options are close, so it's pure luck.
Maybe add one of the many singers who famously died at 29?
Jesus and Alexander the Great both died around 30, so they would work as long as the options are spaced far enough apart (20, 30, 40).
This quiz has great potential with a few tweaks!
