A county library wants patrons to reserve a study room by phone or chat without a clerk on every request. The system must ask follow-up questions and confirm a slot. The library is not sending a batch of flyers to another language. Which AWS service matches this job?

Short Explanation
Think of a clerk on the phone who asks follow-ups and books the room. Amazon Lex is that conversation, voice or chat. Translate is a one-way pile of flyers, Comprehend just scores a finished paragraph, and Polly can talk but cannot confirm a slot.
Full Explanation
Amazon Lex is the managed conversational-bot service for interactive voice or text dialogs, which is how a patron can reserve a room without a clerk. Amazon Translate is one-way document conversion, not a booking conversation. Amazon Comprehend extracts insights from text and does not run a reservation dialog. Amazon Polly can speak a line but does not ask follow-ups or confirm a slot by itself.
