@@ -17,6 +17,13 @@ Your task: Generate an **enumeration** multiple-choice question that tests count
 - Avoid trivially small counts (e.g., "How many people?" when only 1 is visible).
 - Each option must begin with "A. ", "B. ", "C. ", or "D. ".
 
+## Prohibited Patterns
+
+- Do NOT fabricate counts or list items absent from the provided material — no invented quantities, names, or sequences that are not explicitly confirmable from the subtitles or frames.
+- Do NOT construct numerical options in ascending or descending order where the correct answer is the extreme value — shuffle the magnitudes across options.
+- Do NOT write a question where multiple counting interpretations could yield different correct answers — the scope of "what to count" must be unambiguous.
+- Do NOT ask questions answerable by common sense about typical quantities (e.g., "How many wheels does the car have?") — the count must require watching this specific content.
