+        for fluff or ambiguity; clarity is key here, especially for someone who, presumably,
+        knows what they're looking for.\\n\\nNext, I need to retrieve the relevant
+        knowledge. Capital of France... Paris. Simple fact. Solidly established. No
+        debate.\\n\\nNow, how do I formulate the response? The user is likely very
+        well-versed in the specifics of cities and government, so I'll keep it concise
+        and accurate. A direct answer is all that's required. \\\"The capital of France
+        is Paris.\\\" That's it. Succinct, complete, and correct. Done.\\n\\n\\n\",\n
