[Next.js 13 useParams](https://nextjs.org/docs/app/api-reference/functions/use-params)

The issue is about creating a detail page to view questions and answers. The reference points to Next.js 13 useParams for dynamic routing. Start by examining the existing page structure in the app directory to see how data is fetched and passed. Look for similar page components to understand the pattern. Implement the detail page using the dynamic route parameter to fetch and display the specific question and answer data.
