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.

Passage: A dip in arrivals from Britain, its biggest tourist market, has pushed Paris to re-think the way it packages itself and throw off some of the sniffy stereotypes it has been saddled with. On Tuesday, the tourist board for the Paris region launched a new ad campaign aimed at Britons that, far from flaunting its well-known monuments and museums, seeks to portray the French capital as an energetic, youthful and trendy city.
