Article: During the last decade, Philadelphia experienced a large shift in its age profile. In 2000, the city's population pyramid had a largely stationary shape. In 2013, the city took on an expansive pyramid shape, with an increase in the three millennial age groups, 20 to 24, 25 to 29, and 30 to 34. The city's 25- to 29-year-old age group was the city's largest age cohort. According to the 2010 Census, 343,837 (22.5%) were under the age of 18; 203,697 (13.3%) from 18 to 25; 434,385 (28.5%) from 25 to 44; 358,778 (23.5%) from 45 to 64; and 185,309 (12.1%) who were 65 years of age or older. The median age was 33.5 years. For every 100 females there were 89.4 males. For every 100 females age 18 and over, there were 85.7 males. The city had 22,018 births in 2013, down from a peak 23,689 births in 2008. Philadelphia's death rate was at its lowest in at least a half-century, 13,691 deaths in 2013. Another factor attributing to the population increase is Philadelphia's immigration rate. In 2013, 12.7 percent of residents were foreign-born, just shy of the national average, 13.1 percent.

Question: How many people at the last census were under 18?

Article: The foundations of the British Empire were laid when England and Scotland were separate kingdoms. In 1496 King Henry VII of England, following the successes of Spain and Portugal in overseas exploration, commissioned John Cabot to lead a voyage to discover a route to Asia via the North Atlantic. Cabot sailed in 1497, five years after the European discovery of America, and although he successfully made landfall on the coast of Newfoundland (mistakenly believing, like Christopher Columbus, that he had reached Asia), there was no attempt to found a colony. Cabot led another voyage to the Americas the following year but nothing was heard of his ships again.

Question: When was John Cabot's voyage commissioned?
Ans: 1496


Article: The tourism industry began in the early 19th century when foreigners visited the Alps, traveled to the bases of the mountains to enjoy the scenery, and stayed at the spa-resorts. Large hotels were built during the Belle Époque; cog-railways, built early in the 20th century, brought tourists to ever higher elevations, with the Jungfraubahn terminating at the Jungfraujoch, well above the eternal snow-line, after going through a tunnel in Eiger. During this period winter sports were slowly introduced: in 1882 the first figure skating championship was held in St. Moritz, and downhill skiing became a popular sport with English visitors early in the 20th century, as the first ski-lift was installed in 1908 above Grindelwald.

Question: When were large hotels built in the Alps? 
Ans:
during the Belle Époque
