Detailed Instructions: 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.
See one example below:
Problem: 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: 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".

Problem: Passage: Some ministers also expressed concern about the weakening dollar, which reduces their revenues from oil exports. The inclusion of Angola is the first time the group has expanded since Gabon joined in 1975. Question: What events were completed before the ministers expressed their concern? Events: ['expressed', 'weakening', 'reduces', 'inclusion', 'is', 'expanded', 'joined']
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.
