In this task, a passage will be given and the goal is to identify an event from the passage. An event is defined as a single word representing something that happened, is happening, or may happen. An event can be factual or hypothetical, positive or negative, certain or uncertain. While most events are based on verbs, an event can also be based on a noun (ex. storm, snow, rainfall) or a copula verb (is, was, been, etc.). The event must not be a pronoun or an adjective. For noun events with multiple words, use the last word in the phrase as event.

Example Input: Passage: Reigning world number one Bob and Mike Bryan recovered from their lacklustre tournament opener in their Tuesday's Red Group match at Tennis Masters Cup, crashing former top-ranked pair Mark Knowles and Daniel Nestor 6-4, 6-4. Earlier in the day, fifth-seeded Leander Paes of India and Nedad Zimonjic from Serbia and Montenegro claimed their second win in Shanghai, defeating seventh-seeded Australian duo Wayne Arthurs and Paul Hanley 7-6(3), 7-6 (6) in two hours.
Example Output: recovered

Example Input: Passage: Many workers were advised to operate from home and some companies, such as telecoms firm Reach, temporarily relocated operations to outlying districts, leaving only a skeleton staff for the duration of the six-day meeting. Instead of office workers crowding the sidewalks of Wan Chai's Gloucester Road, groups of police stood ready in case protests turned violent, part of a massive security operation involving 9,000 officers staged for the WTO meeting.
Example Output: meeting

Example Input: Passage: "This could be the start of their retaliatory attacks," said a military official who asked not to be named.
