Problem: Please answer a question about the following article about Middle Ages:
Although the Palaeologi emperors recaptured Constantinople from the Western Europeans in 1261, they were never able to regain control of much of the former imperial lands. They usually controlled only a small section of the Balkan Peninsula near Constantinople, the city itself, and some coastal lands on the Black Sea and around the Aegean Sea. The former Byzantine lands in the Balkans were divided between the new Kingdom of Serbia, the Second Bulgarian Empire and the city-state of Venice. The power of the Byzantine emperors was threatened by a new Turkish tribe, the Ottomans, who established themselves in Anatolia in the 13th century and steadily expanded throughout the 14th century. The Ottomans expanded into Europe, reducing Bulgaria to a vassal state by 1366 and taking over Serbia after its defeat at the Battle of Kosovo in 1389. Western Europeans rallied to the plight of the Christians in the Balkans and declared a new crusade in 1396; a great army was sent to the Balkans, where it was defeated at the Battle of Nicopolis. Constantinople was finally captured by the Ottomans in 1453.
What tribe of Turks emerged in 13th century Anatolia?
A: Ottomans
Problem: Please answer a question about the following article about Samurai:
Following the Battle of Hakusukinoe against Tang China and Silla in 663 AD that led to a Japanese retreat from Korean affairs, Japan underwent widespread reform. One of the most important was that of the Taika Reform, issued by Prince Naka no Ōe (Emperor Tenji) in 646 AD. This edict allowed the Japanese aristocracy to adopt the Tang dynasty political structure, bureaucracy, culture, religion, and philosophy. As part of the Taihō Code, of 702 AD, and the later Yōrō Code, the population was required to report regularly for census, a precursor for national conscription. With an understanding of how the population was distributed, Emperor Mommu introduced a law whereby 1 in 3–4 adult males was drafted into the national military. These soldiers were required to supply their own weapons, and in return were exempted from duties and taxes. This was one of the first attempts by the Imperial government to form an organized army modeled after the Chinese system. It was called "Gundan-Sei" (軍団制) by later historians and is believed to have been short-lived.[citation needed]
What was the effect of the Battle of Hakusukinoe?
A: a Japanese retreat from Korean affairs

Problem: Please answer a question about the following article about Paris:
After a tentative creation of several smaller suburban cemeteries, the Prefect Nicholas Frochot under Napoleon Bonaparte provided a more definitive solution in the creation of three massive Parisian cemeteries outside the city limits. Open from 1804, these were the cemeteries of Père Lachaise, Montmartre, Montparnasse, and later Passy; these cemeteries became inner-city once again when Paris annexed all neighbouring communes to the inside of its much larger ring of suburban fortifications in 1860. New suburban cemeteries were created in the early 20th century: The largest of these are the Cimetière parisien de Saint-Ouen, the Cimetière parisien de Pantin (also known as Cimetière parisien de Pantin-Bobigny, the Cimetière parisien d'Ivry, and the Cimetière parisien de Bagneux).[citation needed] Some of the most famous people in the world are buried in Parisian cemeteries.
What is the largest of the cemeteries created in the 20th centuries?
A:
Cimetière parisien de Saint-Ouen
