The user wants an answer key for a 14-page scanned PDF at /tmp/workspace/attachments/ecf10955-8ec3-4d83-b0a0-f36c623b9158/SET 2.pdf. It is likely a medical multiple-choice paper. Create a complete answer key: inspect/render pages, perform OCR or visual analysis as possible, identify every question and correct option. Follow mandatory skills for medical/PDF as applicable. Return a concise numbered list Q# -> answer (with wording if needed) plus explicit uncertainty for unreadable questions. Do not create unnecessary output files. Use available tools and external current search only as needed.
