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: Gabon is one of the few countries in central Africa that has never -- since its independence from France -- been affected by an armed conflict. It is a small country with only about 1.5 million people, yet Gabon's people has one of the highest per capita incomes in Africa, largely due to the country's substantial revenues from petroleum exports.
