Ask a real question, then open the citations to see what they actually say.

Take on the committee's question

You volunteer at Linden Street Café. The committee wants to know whether to stop serving every drink in a single-use cup, and asks you for a one-page brief. In this course you research it with Perplexity, a search tool that answers in sentences and cites the web pages it used. The café and its people are fictional; the question is real, so your searches will cite real pages. A free Perplexity account is enough for every lesson. Example replies and example sources in these lessons are authored illustrations, not recordings of Perplexity; your answers and citations will differ.
