Question: Based on the similar shifts underway the nation's economy after 1960, Philadelphia experienced a loss of manufacturing companies and jobs to lower taxed regions of the USA and often overseas. As a result, the economic base of Philadelphia, which had historically been manufacturing, declined significantly. In addition, consolidation in several American industries (retailing, financial services and health care in particular) reduced the number of companies headquartered in Philadelphia. The economic impact of these changes would reduce Philadelphia's tax base and the resources of local government. Philadelphia struggled through a long period of adjustment to these economic changes, coupled with significant demographic change as wealthier residents moved into the nearby suburbs and more immigrants moved into the city. The city in fact approached bankruptcy in the late 1980s. Revitalization began in the 1990s, with gentrification turning around many neighborhoods and reversing its decades-long trend of population loss.
Is there an answer to this question: When did the city near bankruptcy?

Answer: late 1980s


Question: The metro leaves the Rodoviária (bus station) and goes south, avoiding most of the political and tourist areas. The main purpose of the metro is to serve cities, such as Samambaia, Taguatinga and Ceilândia, as well as Guará and Águas Claras. The satellite cities served are more populated in total than the Plano Piloto itself (the census of 2000 indicated that Ceilândia had 344,039 inhabitants, Taguatinga had 243,575, whereas the Plano Piloto had approximately 400,000 inhabitants), and most residents of the satellite cities depend on public transportation.
Is there an answer to this question: What is the Rodoviária?

Question: The Germans developed massive reinforced concrete blockhouses, some more than six stories high, which were known as Hochbunker "High Bunkers" or "Flaktürme" flak towers, on which they placed anti-aircraft artillery. Those in cities attacked by the Allied land forces became fortresses. Several in Berlin were some of the last buildings to fall to the Soviets during the Battle of Berlin in 1945. The British built structures such as the Maunsell Forts in the North Sea, the Thames Estuary and other tidal areas upon which they based guns. After the war most were left to rot. Some were outside territorial waters, and had a second life in the 1960s as platforms for pirate radio stations.
Is there an answer to this question: What structure did the British build in the North Sea?

Answer: Maunsell Forts


Question: In the Scottish Enlightenment, Scotland's major cities created an intellectual infrastructure of mutually supporting institutions such as universities, reading societies, libraries, periodicals, museums and masonic lodges. The Scottish network was "predominantly liberal Calvinist, Newtonian, and 'design' oriented in character which played a major role in the further development of the transatlantic Enlightenment". In France, Voltaire said "we look to Scotland for all our ideas of civilization." The focus of the Scottish Enlightenment ranged from intellectual and economic matters to the specifically scientific as in the work of William Cullen, physician and chemist; James Anderson, an agronomist; Joseph Black, physicist and chemist; and James Hutton, the first modern geologist.
Is there an answer to this question: Who was the first modern geologist?

Answer:
James Hutton
