Definition: 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.
Input: Passage: Baghdad earlier this week sent nine helicopters to the south, already violating the "no-fly" zone, to wait for the Iraqis returning from the pilgrimage to Mecca in Saudi Arabia. The flight to Mosul also violates a northern exclusion zone set up shortly after the 1991 Gulf War to protect Iraqi Kurds from air attack by Baghdad.
Output:
What event has already finished?
