Definition: 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.
Input: Passage: The appeal was sparked by fears that new clashes could erupt on Sydney beaches this weekend. Dozens of people were injured and arrested in the violence, in which white mobs set out to "reclaim the beach" from groups of Lebanese-Australians accused of intimidating other beachgoers with boorish behaviour at weekends.
