The headings of this article can help us to determine the central idea. The first part of the article starts with a narrative about a ship carrying disease. Then the headings give the main idea of each section. We know that the article begins with "The Arrival and Spread of the Black Plague" then moves to "Symptoms and Devestation", before describing the "Societal Effects", and then ends with "The Black Death's Legacy".
