+
+for item in ds["test"]:
+   
+    # Start with a clear task description
+    prompt = (
+        "You are a highly intelligent assistant. "
+        "Based on the given image, answer the multiple-choice question by selecting the correct option.\n\n"
+        "Question:\n" + item["question"] + "\n\n"
+        "Options:\n"
+    )

+    
+    # Add a concluding sentence to encourage selection of the answer
+    prompt += "\nSelect the best option by choosing its number."
