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.
Example: Passage: I submitted the hit. The hit was approved, and then I was paid.
Example solution: What happened after I submitted the hit?
Example explanation: This is a valid temporal question based on the given paragraph. Events approved and paid have a temporal relation "after" with the event submitted.

Problem: Passage: President Bush on Tuesday said the United States may extend its naval quarantine to Jordan's Red Sea port of Aqaba to shut off Iraq's last unhindered trade route. In another mediation effort, the Soviet Union said today it had sent an envoy to the Middle East on a series of stops to include Baghdad.

Solution: What event has already happened?
