Being able to answer these questions is a pre-requisite for AGI. After all, there ARE humans capable of doing that, so, if the AI can't do it no matter how hard it tries, then that means there ARE human capabilities that the AI can't replicate (thus, it isn't an AGI). And it seems like no LLM is making any progress at all in that kind of prompt, which is why I use it as a core benchmark on my "AGI-meter".
