Part 1. 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.
Part 2. Example
Passage: I submitted the hit. The hit was approved, and then I was paid.
Answer: What happened after I submitted the hit?
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.
Part 3. Exercise
Passage: "Of course, that is, as long as they accept that we are a country that does not tolerate any reduction of its independence, and based on the principles of equality, reciprocity, non-interference and mutual respect," he told Communist Party and military leaders at Cuba's first military parade in a decade. "Until that happens, after almost half a century, we are prepared to wait patiently for the moment when common sense takes root in the halls of power in Washington," he said.
Answer:
What event has already finished?
