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.

OK. solve this:
Passage: The situation is increasingly tense as rebels have said they will be in Kinshasa before June and the government has been cracking down on opposition protests in the capital. It was apparently the first time in the Zairean crisis that an embassy has urged all its nationals to leave the country.
Answer:
