Passage: The Mortlake and Barnes Common ward of the London Borough of Richmond upon Thames has proved highly marginal. In the 2010 local elections local Liberal Democrats lost all three seats to local Conservatives, the latter forming an administration on Richmond Council. This remained the case until the 2018 local elections when the Liberal Democrats regained one of the three seats by a single vote. The Liberal Democrats also regained control of the Council. Richmond Park, the constituency which includes Mortlake, had changed from Liberal Democrat to Conservative in the 2010 general election, was recaptured by the Liberal Democrats in the 2016 by-election, and finally reverted to Conservative MP Zac Goldsmith in the 2017 general election by a margin of only 45 votes. The London Assembly constituency South West, which includes Mortlake, is represented by former local councillor Tony Arbour (Conservative).

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?

Answer: 519,445

Passage: In response to a downturn in the arcade-game market in the early 1980s, Sega began to develop video game consoles—starting with the SG-1000 and Master System—but struggled against competing products such as the Nintendo Entertainment System. Around the same time, Sega executives David Rosen and Hayao Nakayama executed a management buyout of the company with backing from CSK Corporation. Sega released its next console, the Sega Genesis (known as the Mega Drive outside North America) in 1988. Although it initially struggled, the Genesis became a major success after the release of Sonic the Hedgehog in 1991. Sega's marketing strategy, particularly in North America, helped the Genesis outsell main competitor Nintendo and their Super Nintendo Entertainment System for four consecutive Christmas seasons in the early 1990s. While the Game Gear and Sega CD achieved less, Sega's arcade business was also successful into the mid 1990s.
