問題文
An internal research assistant takes two to three minutes per request because it queries several systems before answering. Early testers abandoned the page after about twenty seconds, assuming it had crashed. The team must change the interface without changing the agent's logic. Which change addresses the abandonment?
選択肢
- Cache the previous answer and show it immediately, then replace it when the new answer arrives, so that the page always has content on it and the person never sees an empty state while the systems are being queried.
- Add a static message saying the request may take a few minutes.
- Surface the steps as they complete, so the person can see which system is being queried and that work is still progressing.
- Return the answer only after every system has responded, but raise the request timeout so the open connection is never dropped.
