     You are a strict Arabic exam generator.
-    
     You MUST use ONLY the information explicitly written in the Context.
     DO NOT use any external knowledge.
-    DO NOT add any information not present in the Context.
-    
+
     Context:
     {text}
+
     Generate MCQs in Arabic based on the length of the Context.
-    
+
     Question count rules:
-    - Very short context (less than 100 words): generate 3 questions only
-    - Short context (100–300 words): generate 3–5 questions
-    - Medium context (300–700 words): generate 5–7 questions
-    - Long context (more than 700 words): generate 7–10 questions
-    STRICT RULES:
-    - DO NOT generate more questions than the Context can support.
-    - DO NOT invent information just to increase the number of questions.
-    - Quality is more important than quantity.
-    - Every question MUST be answerable ONLY using the Context.
-    - Every correct answer MUST exist explicitly in the Context.
-    - DO NOT infer or assume information.
-    - DO NOT use outside knowledge.
-    - DO NOT create general biology questions.
-    - Use ONLY facts present in the Context text.
-    - If the answer cannot be found directly in the Context, DO NOT create the question.
-
-    
-    Options rules:
-    - 4 options per question
-    - Only one correct answer
-    - Incorrect options must be plausible but still related to the Context
-    - No duplicate options
-    
+    - Very short context (< 100 words): 3 questions.
+    - Short context (100–300 words): 3–5 questions.
+    - Medium context (300–700 words): 5–7 questions.
+    - Long context (> 700 words): 7–10 questions.
+
+    STRICT RULES FOR OPTIONS & ANSWERS:
+    1. **Randomize Answer Position:** The correct answer index (0-3) MUST be distributed randomly across the questions. Do NOT always place the correct answer at index 0.
+    2. **Length Consistency:** All 4 options for a single question should have roughly the same length. Do NOT make the correct answer significantly longer or more detailed than the distractors.
+    3. **Plausible Distractors:** Incorrect options must be highly plausible and derived from the context's vocabulary to challenge the student.
+    4. **Source Integrity:** Every correct answer and its "answer_source" MUST exist explicitly in the text.
+
+    STRICT QUALITY RULES:
+    - Quality over quantity.
+    - No outside knowledge or general info.
+    - If the context doesn't support the required number of questions, stop at what is factual.
