Ex Input:
Passage: The gastronomic symbol of the région is undoubtedly the Choucroute, a local variety of Sauerkraut. The word Sauerkraut in Alsatian has the form sûrkrût, same as in other southwestern German dialects, and means "sour cabbage" as its Standard German equivalent. This word was included into the French language as choucroute. To make it, the cabbage is finely shredded, layered with salt and juniper and left to ferment in wooden barrels. Sauerkraut can be served with poultry, pork, sausage or even fish. Traditionally it is served with Strasbourg sausage or frankfurters, bacon, smoked pork or smoked Morteau or Montbéliard sausages, or a selection of other pork products. Served alongside are often roasted or steamed potatoes or dumplings.

Ex Output:
What word does Choucroute come from?

Passage: The three brothers—Rurik, Sineus, and Truvor—established themselves in Novgorod, Beloozero, and Izborsk, respectively. Two of the brothers died, and Rurik became the sole ruler of the territory and progenitor of the Rurik Dynasty. A short time later, two of Rurik’s men, Askold and Dir, asked him for permission to go to Tsargrad (Constantinople). On their way south, they discovered "a small city on a hill," Kiev, captured it and the surrounding country from the Khazars, populated the region with more Varangians, and "established their dominion over the country of the Polyanians."

Ex Output:

Passage: Universal Studios was founded by Carl Laemmle, Mark Dintenfass, Charles O. Baumann, Adam Kessel, Pat Powers, William Swanson, David Horsley, Robert H. Cochrane[a] and Jules Brulatour. One story has Laemmle watching a box office for hours, counting patrons and calculating the day's takings. Within weeks of his Chicago trip, Laemmle gave up dry goods to buy the first several nickelodeons. For Laemmle and other such entrepreneurs, the creation in 1908 of the Edison-backed Motion Picture Trust meant that exhibitors were expected to pay fees for Trust-produced films they showed. Based on the Latham Loop used in cameras and projectors, along with other patents, the Trust collected fees on all aspects of movie production and exhibition, and attempted to enforce a monopoly on distribution.

Ex Output:

Who founded Universal Studios in Chicago?
