Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: approved, paid
Reason: 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 instance: Passage: "There is evidence that in regions where the majority of men are circumcised, HIV infection is lower than in regions where circumcision is not practiced." Five southern African countries hard-hit by the AIDS pandemic -- Botswana, Lesotho, Swaziland, Tanzania and Zambia -- are in talks with the UN AIDS agency on making circumcision more accessible to men. Question: What began before there was evidence? Events: ['is', 'circumcised', 'infection', 'is', 'circumcision', 'practiced', 'hard-hit', 'pandemic', 'are', 'talks', 'making', 'circumcision']
Student:
circumcised
