Input: Consider Input: Its knowledge and uses spread from China through the Middle East to medieval Europe in the 13th century, where the first water powered paper mills were built. Because of paper's introduction to the West through the city of Baghdad, it was first called bagdatikos. In the 19th century, industrial manufacture greatly lowered its cost, enabling mass exchange of information and contributing to significant cultural shifts. In 1844, the Canadian inventor Charles Fenerty and the German F. G. Keller independently developed processes for pulping wood fibres.

Output: In what century did the papermaking process spread from China to Europe?


Input: Consider Input: The Neolithic 2 (PPNB) began around 8,800 BCE according to the ASPRO chronology in the Levant (Jericho, Israel). As with the PPNA dates, there are two versions from the same laboratories noted above. This system of terminology, however, is not convenient for southeast Anatolia and settlements of the middle Anatolia basin. This era was before the Mesolithic era.[citation needed] A settlement of 3,000 inhabitants was found in the outskirts of Amman, Jordan. Considered to be one of the largest prehistoric settlements in the Near East, called 'Ain Ghazal, it was continuously inhabited from approximately 7,250 – 5,000 B.

Output: When did the The Neolithic 2 (PPNB) era start?


Input: Consider Input: In the American Old West, policing was often of very poor quality.[citation needed] The Army often provided some policing alongside poorly resourced sheriffs and temporarily organized posses.[citation needed] Public organizations were supplemented by private contractors, notably the Pinkerton National Detective Agency, which was hired by individuals, businessmen, local governments and the federal government. At its height, the Pinkerton Agency's numbers exceeded those of the United States Army.[citation needed]
