The correct response is: "It was a plague that travelled along the Silk Road and devastated communities and economies."
The Black Death, also known as the Bubonic Plague, occurred in the mid-14th century and resulted in the deaths of an estimated 25 million people in Europe alone, which was about one-third of the continent's population at the time. Originating in Asia, it spread through trade routes, including the Silk Road, as well as through fleas and rats that were common on ships. The pandemic had profound effects not only on the population, leading to labor shortages, but also on economies, societies, and the overall course of European history, contributing to shifts in power and social structures.
