You have a scanned PDF exam paper (28 pages) that has been converted to PNG images. Each page image is stored at /tmp/workspace/pdf_pages/page_01.png through page_28.png. Your job is to: 1. Read ALL 28 page images using analyse_media tool. Pass the file URL as: file:///tmp/workspace/pdf_pages/page_01.png (for page 1), etc. 2. Extract ALL questions from the paper (they appear to be MCQs - multiple choice questions). 3. For EACH question, provide: - The full question text - All answer options (A, B, C, D) - The CORRECT answer (clearly marked) - A detailed explanation of WHY that answer is correct - An explanation of WHY each incorrect option is wrong IMPORTANT INSTRUCTIONS: - Analyze ALL 28 pages - don't skip any - This is likely a medical/USMLE/MBBS exam paper based on the filename "2024.pdf" - Be thorough - explain each option in detail - If a page has no question (just images or tables), note that and move on - Return the complete answer key with explanations for every single question found Format your response as: **Question [N]: [Full question text]** Options: A) ... B) ... C) ... D) ... **Correct Answer: [Letter] - [Option text]** **Explanation:** - **Correct (A/B/C/D):** [Why this is correct - detailed] - **Wrong (A/B/C/D):** [Why this is wrong] - **Wrong (A/B/C/D):** [Why this is wrong] - **Wrong (A/B/C/D):** [Why this is wrong] --- Analyze every single page and every single question. Return the complete compiled answer with explanations.
