Q: Passage: Columbia, formerly Wright's Ferry, is a borough (town) in Lancaster County, Pennsylvania, 28 miles (45 km) southeast of Harrisburg on the east (left) bank of the Susquehanna River, across from Wrightsville and York County and just south of U.S. Route 30. The settlement was founded in 1726 by Colonial English Quakers from Chester County led by entrepreneur and evangelist John Wright. Establishment of the eponymous Wright's Ferry, the first commercial Susquehanna crossing in the region, inflamed territorial conflict with neighboring Maryland but brought growth and prosperity to the small town, which was just a few votes shy of becoming the new United States' capital. Though besieged for a short while by Civil War destruction, Columbia remained a lively center of transport and industry throughout the 19th century, once serving as a terminus of the Pennsylvania Canal. Later, however, the Great Depression and 20th-century changes in economy and technology sent the borough into decline. It is notable today as the site of one of the world's few museums devoted entirely to horology.
 Link Information: As of the 2010 census, the population was 519,445. Question: What is the current population of the county where Columbia, PA is located?

A: Answer: 519,445

Q: Passage: Tomić belonged to the first class of six Serbian pilots trained in France in 1912. In August 1914, he participated in the first aerial dogfight of the war, when he exchanged gunfire with an Austro-Hungarian plane over western Serbia. In the winter of 1915, during the Serbian Army's retreat across Albania to the Greek island of Corfu, he evacuated General Petar Bojović from Scutari by plane, delivered mail by air and transported the Serbian Government's gold and hard currency reserves from Niš to keep them from falling into enemy hands. Following the occupation of Serbia by the Central Powers, Tomić went to France and flew over the Western Front, where he had one confirmed kill. He returned to the Balkans in late 1916, conducted combat missions over Bulgarian-occupied Macedonia and shot down one enemy plane. Tomić continued flying after the war and became head of the Royal Yugoslav Air Force's pursuit squadron in Novi Sad. During World War II, he was captured by the Germans and detained as a prisoner of war. Tomić left Yugoslavia following the war and settled in the United States with his wife. He died in Chicago in 1962.
 Link Information: The Central Powers consisted of the German Empire and the Austro-Hungarian Empire at the beginning of the war. The Ottoman Empire joined the Central Powers later in 1914. In 1915, the Kingdom of Bulgaria joined the alliance. Question: How many nations were part of the powers that occupied Serbia?

A: Answer: 4

Q: Passage: In 1982, Dome built the RC82 as their first effort in the new Group C category of sports car racing. The chassis was built by March Engineering, whilst the engine was a 3.3-litre Cosworth DFL V8 engine. Dome, with sponsorship from Amada, debuted the car at the 1982 6 Hours of Silverstone, and selected Chris Craft, Raul Boesel and Eliseo Salazar to drive it. It would not prove to be a successful debut, as the car succumbed to fuel pressure issues after 116 laps. Dome then entered Craft and Salazar at the 24 Hours of Le Mans, but the suspension mounting failed after 85 laps, and the team were forced to retire. The RC82 was not used again until the 1983 24 Hours of Le Mans; Nick Mason joined the team, but the car lasted 75 laps before succumbing to clutch failure. Following the race, the RC83 made its debut in the 1000 km of Fuji, with the factory phasing out the RC82.
 Link Information: The engine is a 90°, 2,993 cc V8 with a bore and stroke of 85.67 x 64.897 mm (3.373 x 2.555 in) producing over 400 bhp (408 bhp at 9,000 rpm, 270 ft.lbf torque at 7,000 rpm was quoted) from the start reaching over 500 bhp (510 bhp at 11,200 rpm was quoted) by the end of its Formula 1 career.  Question: How much horsepower did the Cosworth Engine make?

A:
Answer: 510
