You will be given a definition of a task first, then some input of the task.
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.

Output:
