You have a set of 105 image files extracted from a Heart Lecture PDF. They are saved at /tmp/workspace/heart_pages/page_001.jpg through page_105.jpg. Your job is to: 1. Use the analyse_media tool to examine EVERY page image (all 105 pages). The images are local files. To use analyse_media, you need a URL - but these are local files. Instead, use the read_file tool to get the file, or better, use the fetch_image tool to view them. Actually, since these are local files, use the execute tool to convert them to base64 and then use analyse_media... WAIT - actually for local files, use the `fetch_image` tool with the file path formatted as a file URL like: file:///tmp/workspace/heart_pages/page_001.jpg OR better: use execute to run a Python script that uses PIL/Pillow to display the images as base64, then use analyse_media. ACTUALLY - the best approach: Use the `read_file` tool to read each .jpg file - no that won't work for images. The CORRECT approach: These JPG files are in the sandbox. Use the `analyse_media` tool with the URL set to the file path directly (some backends support file:// URLs). Try: analyse_media(media_url="file:///tmp/workspace/heart_pages/page_001.jpg") If that doesn't work, use execute to serve the files or encode them. IMPORTANT: Focus specifically on pages that contain QUESTIONS (multiple choice questions, numbered questions, quiz-style questions about the heart/cardiology). Skip pages that are purely lecture slides with no questions. For each question page: - Extract the full text of each question - Extract all answer choices (A, B, C, D, etc.) - Identify the correct answer Return a complete, structured list of ALL questions with their correct answers in this format: Q1. [Question text] A) option A B) option B C) option C D) option D **Correct Answer: X) [text]** If a page has a question followed by an answer/explanation on a later page, capture both. Use your analyse_media budget wisely - you have up to 10 analyse_media calls. Prioritize pages most likely to have questions (often appear near the end of lecture slides, or are clearly formatted as quiz pages). You can use fetch_image to view images too. Start by looking at the first few pages to understand the structure, then focus on question pages. Look at pages throughout the PDF - pages 1-10, then 30-40, then 50-60, then 80-105 to find where questions appear. Return ALL questions you find with their correct answers.
