+    "1: The response fails to address the instructions, providing irrelevant, incorrect, or excessively verbose information that detracts from the user's request.\n",
+    "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",
+    "5: The response fully adheres to the instructions, providing a clear, accurate, and relevant answer in a concise and efficient manner. It addresses all aspects of the request without unnecessary details or elaboration\n",
