A teacher wants his students to watch a previously recorded video and answer the questions contained in the video. Which tool would be most suitable for this purpose?

EdPuzzle lets a teacher embed questions directly into a recorded video so students answer while they watch.

Avornote is not an established educational video-question tool, so it does not fit the purpose.

Google Docs is a collaborative word processor for text documents, not for interactive video assessment.

Strapole is not a recognised tool for embedding questions in videos.

EdPuzzle also tracks whether each student watched and how they responded, giving formative data.

Embedding checks inside video is a strategy of interactive video learning that keeps viewers active.
