Article: The earliest record of the location appears as Sao Joao on a Portuguese map by Pedro Reinel in 1519. When John Rut visited St. John's in 1527 he found Norman, Breton and Portuguese ships in the harbour. On 3 August 1527, Rut wrote a letter to King Henry on the findings of his voyage to North America; this was the first known letter sent from North America. St. Jehan is shown on Nicholas Desliens' world map of 1541 and San Joham is found in Joao Freire's Atlas of 1546. It was during this time that Water Street was first developed, making it the oldest street in North America.[dubious discuss]

Question: What year did John Rut visit St. John's?
Ans: 1527

Article: The military effectiveness of bombing varied. The Luftwaffe dropped around 45,000 short tons (41,000 t) of bombs during the Blitz disrupting production and transport, reducing food supplies and shaking the British morale. It also helped to support the U-Boat blockade by sinking some 58,000 long tons (59,000 t) of shipping destroyed and 450,000 long tons (460,000 t) damaged. Yet, overall the British production rose steadily throughout this period although there were significant falls during April 1941, probably influenced by the departure of workers of Easter Holidays according to the British official history. The British official history on war production noted the great impact was upon the supply of components rather than complete equipment. In aircraft production, the British were denied the opportunity to reach the planned target of 2,500 aircraft in a month, arguably the greatest achievement of the bombing, as it forced the dispersal of industry. In April 1941, when the targets were British ports, rifle production fell by 25%, filled-shell production by 4.6%, and in smallarms production 4.5% overall. The strategic impact on industrial cities was varied; most took from 1015 days to recover from heavy raids, although Belfast and Liverpool took longer. The attacks against Birmingham took war industries some three months to recover fully from. The exhausted population took three weeks to overcome the effects of an attack.

Question: How long was the recovery of industrial cities from raids?
Ans: most took from 1015 days

Article: Exposure to antibiotics early in life is associated with increased body mass in humans and mouse models. Early life is a critical period for the establishment of the intestinal microbiota and for metabolic development. Mice exposed to subtherapeutic antibiotic treatment (STAT) with either penicillin, vancomycin, penicillin and vancomycin, or chlortetracycline had altered composition of the gut microbiota as well as its metabolic capabilities. Moreover, research have shown that mice given low-dose penicillin (1 g/g body weight) around birth and throughout the weaning process had an increased body mass and fat mass, accelerated growth, and increased hepatic expression of genes involved in adipogenesis, compared to controlled mice. In addition, penicillin in combination with a high-fat diet increased fasting insulin levels in mice. However, it is unclear whether or not antibiotics cause obesity in humans. Studies have found a correlation between early exposure of antibiotics (<6 months) and increased body mass (at 10 and 20 months). Another study found that the type of antibiotic exposure was also significant with the highest risk of being overweight in those given macrolides compared to penicillin and cephalosporin. Therefore, there is correlation between antibiotic exposure in early life and obesity in humans, but whether or not there is a causal relationship remains unclear. Although there is a correlation between antibiotic use in early life and obesity, the effect of antibiotics on obesity in humans needs to be weighed against the beneficial effects of clinically indicated treatment with antibiotics in infancy.

Question: What is one common result of using antibiotics from a young age?
Ans: increased body mass

Article: One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.

Question: When did Houston begin to regain its dependence on the oil industry?
Ans:
2000s
