Given the task definition and input, reply with output. 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.

But advocates of the "victory-still-possible" approach received a bucketful of cold water Sunday from one of the chief architects of the allied victory in the 1991 Gulf War, former chairman of the Joint Chiefs of Staff Colin Powell.
What event has already finished?
