Thats not really 'simple' for an LLM. This is a niche information about a specifc person, LLM's train on massive amount of data, the more a topic is being present in the data, the better will the answers be.
Also, you can/should use the "research" mode for questions like this.
The question is simple and verifiable - it is impressive to me that it’s not contained in the LLM’s body of knowledge - or rather that it can’t reach the answer.
This is niche in the grand scheme of knowledge but Paul Newman is easily one of the biggest actors in history, and the LLM has been trained on a massive corpus that includes references to this.
Where is the threshold for topics with enough presence in the data?
