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 case of Elian is for today's youth what 40 years of the blockade, armed invasions, sabotage and attempts to kill President Fidel Castro were for earlier generations,'' said Cuban journalist Luis Baez, who has written several books about Cuban emigration to the United States. After the rally, state television showed the Cuban exiles in the streets of Miami -- some of them carrying signs demanding ``Freedom for Elian,'' the same battle cry regularly chanted during rallies on this side of the Florida Straits.
