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.
One example is below.
Q: Passage: I submitted the hit. The hit was approved, and then I was paid.
A: What happened after I submitted the hit?
Rationale: This is a valid temporal question based on the given paragraph. Events approved and paid have a temporal relation "after" with the event submitted.
Q: Passage: "When completed, the hydropower station will slightly raise the water levels of the two tributaries and the humidity of the natural reserve will also rise," said Gyina, adding that this will help the growth of the subtropical wildlife in the area, especially the 12,000 hectares of bamboos that giant pandas feast on. The Xiluodu hydropower station will replace local thermal power plants, which means 41 million tons less coal burnt each year, said the official.
A:
What event has already finished?
