Holy shit you’re dense. This isn’t Dark Souls and that’s a video game, not a table-top, theatre of the mind, RPG.
If you can learn that the crate, which is indistinguishable from any other crate, has no reason to be where it is then you can perform further tests to expose whether or not it is a mimic. It will look exactly like a crate the whole time and that’s fine. It’s not a paradox, you’re just not very intelligent.
You’re fifty-two cards short of a deck and making it everyone else’s problem.





There’s also, I think, the weird fucky option were 75% sorta works because the 25% applies to choosing 50% and 50% applies to choosing 25% which means that as long as you don’t choose 0% you’re good?
BUT ALSO, none of the question says it’s talking about itself. It could just mean in general, so we can choose 25% on purpose and then glare at whoever made A and D the same.
