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 portfolio unit of the French bank group Credit Lyonnais told stock market regulators that it bought 43,000 shares of Cie. de Navigation Mixte, apparently to help fend off an unwelcome takeover bid for the company. Earlier yesterday, the Societe de Bourses Francaises was told that a unit of Framatome S.A. also bought Navigation Mixte shares, this purchase covering more than 160,000 shares.
