In this task, a passage will be given and the goal is to generate a question about temporal relations based on that passage. A temporal relation describes the relation between two things with respect to time e.g., something happens/starts/terminates/... immediately/shortly/usually/... before/after/during/... something else.
Your question should include an event, or ask about an event, and should not be a yes/no question.

Let me give you an example: Passage: I submitted the hit. The hit was approved, and then I was paid.
The answer to this example can be: What happened after I submitted the hit?
Here is why: This is a valid temporal question based on the given paragraph. Events approved and paid have a temporal relation "after" with the event submitted.
