A teacher asked her learners to watch a movie two days ago and now she asks them to have a discussion on what would they do, if they were the hero/heroine of the movie? What is this assessment task known as?

An extrapolative task asks learners to extend or project from a given situation/text into a hypothetical scenario — going beyond the text. Asking 'what would YOU do if you were the hero/heroine' requires learners to project themselves into the situation and extrapolate beyond what was actually shown. This is a classic extrapolative reading/viewing comprehension task that develops higher-order thinking by extending the original content.
