        "reasoning_content":"Okay, let's see. The user is asking about the answer to the Great Question of Life, the Universe, and Everything. Hmm, I remember that this is a reference to \"The Hitchhiker's Guide to the Galaxy\" by Douglas Adams. In the book, a supercomputer named Deep Thought was built to calculate the answer to this ultimate question. After a lot of time and processing, the computer comes up with the number 42. But then the characters realize they didn't actually know what the question was. So the answer is 42, but the joke is that the question isn't really known.\n\nWait, but maybe the user is looking for a more philosophical answer? Like, not just the fictional reference. But given the way the question is phrased, \"the Great Question of Life, the Universe, and Everything\" is almost certainly pointing to the Hitchhiker's Guide joke. The answer is famously 42. I should confirm that I'm not missing any other context here. Maybe check if there's another interpretation, but I don't think so. This is a well-known pop culture reference. So the answer is 42, and maybe a brief explanation about the book reference to be helpful."
