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 proposed BellSouth-LIN cellular company, including the newly acquired Metromedia stake, would give the new entity 55 million potential customers, including about 35 million in the nation's top 10 markets. Mr. Leon of Bear Stearns speculated that McCaw, in an attempt to buy time, might consider filing an antitrust suit against BellSouth with the Justice Department and U.S. District Judge Harold Greene, who oversees enforcement of the consent decree that broke up the Bell system in 1984.
