A stronger version
Prepare a comparison of workshop venues from the supplied requirements and approved options. Use document search to locate the requirements, then spreadsheet tools to compare each option against every requirement. Use only the supplied material. Stop when every option has an answer for every requirement, with a document and page or section supporting each answer. Use "unknown" only after checking the supplied material; list the specific sections checked for that requirement and explain what information they lack, so the reader can verify each unknown against those sections. Return the comparison and any unresolved questions. If a required tool or source is unavailable, report that limit instead of claiming the comparison is complete. Do not contact anyone or make bookings.
