In this task, you will be given a passage, a question and a list of single-word events identified from the passage. The goal is to point out all events from the given event list that can answer the question. If a question is unanswerable or none of the events answer the question, output should be empty.
One example: Passage: I submitted the hit. The hit was approved, and then I was paid. Question: What happened after I submitted the hit? Events: ['submitted', 'approved', 'paid'].
Solution is here: approved, paid
Explanation: From the passage, we can infer that events approved and paid happened after the event submitted. Therefore, the answer to this question is "approved, paid".

Now, solve this: Passage: The coaster has the seating capacity of 25 people, but some 45 to 50 people were on board when the accident occurred. Ambulances of the aid groups, busy in the quake-relief activities in the region, rushed to the site of the accident and started shifting the injured to local hospitals. Question: What event has begun but has not finished? Events: ['has', 'were', 'accident', 'busy', 'activities', 'rushed', 'accident', 'started', 'shifting', 'occurred']
Solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
