I flipped the switch in the mod panel so that only you can add answers to this @TimTensen , otherwise anyone could add an answer for every year (or a random text answer). If you want to do this you can, but you should write in the description what kind of answers you will accept and how you intend to resolve it

Otherwise leave it as it is now (where only you can add answers) and people will assume it resolves to the "next" year chronologically

They can also be renamed to represent buckets, e.g.

2023-2030

2031-2040

2041-2050

2050+

though I think people will understand it as it is now!
