Example Input: Passage: Jesuit missionary Eusebio Francisco Kino visited the Santa Cruz River valley in 1692, and founded the Mission San Xavier del Bac in 1700 about 7 mi (11 km) upstream from the site of the settlement of Tucson. A separate Convento settlement was founded downstream along the Santa Cruz River, near the base of what is now "A" mountain. Hugo O'Conor, the founding father of the city of Tucson, Arizona authorized the construction of a military fort in that location, Presidio San Agustin del Tucson, on August 20, 1775 (near the present downtown Pima County Courthouse). During the Spanish period of the presidio, attacks such as the Second Battle of Tucson were repeatedly mounted by Apaches. Eventually the town came to be called "Tucson" and became a part of Sonora after Mexico gained independence from Spain in 1821. Question: What religion was Kino?
Example Output: Jesuit

Example Input: Passage: When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of non-discrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years. Question: Why did thousands of new workers flock to Houston?
Example Output: defense jobs

Example Input: Passage: The 2011 census recorded that 2,998,264 people or 36.7% of London's population are foreign-born making London the city with the second largest immigrant population, behind New York City, in terms of absolute numbers. The table to the right shows the most common countries of birth of London residents. Note that some of the German-born population, in 18th position, are British citizens from birth born to parents serving in the British Armed Forces in Germany. With increasing industrialisation, London's population grew rapidly throughout the 19th and early 20th centuries, and it was for some time in the late 19th and early 20th centuries the most populous city in the world. Its population peaked at 8,615,245 in 1939 immediately before the outbreak of the Second World War, but had declined to 7,192,091 at the 2001 Census. However, the population then grew by just over a million between the 2001 and 2011 Censuses, to reach 8,173,941 in the latter enumeration. Question: London is second only to what city in terms of its foreign population?
Example Output:
New York City
