Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: Singapore has doubled the avian flu tests on local and migratory birds from once every two weeks to once a week, Channel NewsAsia reported on Thursday. The measure is to monitor possible bird flu virus among some 20, 000 migratory birds flying into the city state during the winter months and to prevent local birds and poultry raised on farms from getting infected.
