A listening stimulus —

The correct option is presents an information gap activity such as giving directions.

Explanation:

In language teaching and assessment, a listening stimulus refers to an audio prompt, text, or authentic real-life communicative situation designed to trigger listening comprehension and subsequent language production or task completion.

An information gap activity (such as listening to spoken instructions or directions to map out a route) acts as an effective listening stimulus. In such tasks, one student or listener has information that another lacks, creating a natural, communicative necessity to listen carefully, process the spoken input, and use it to complete a task.
