+    "2: The response partially addresses the instructions but includes significant inaccuracies, irrelevant details, or excessive elaboration that detracts from the main task.\n",
+    "3: The response follows the instructions with some minor inaccuracies or omissions. It is generally relevant and clear, but may include some unnecessary details or could be more concise.\n",
+    "4: The response adheres to the instructions, offering clear, accurate, and relevant information in a concise manner, with only occasional, minor instances of excessive detail or slight lack of clarity.\n",
