With the collapse of Roman rule in the early 5th century, London ceased to be a capital and the walled city of Londinium was effectively abandoned, although Roman civilisation continued in the St Martin-in-the-Fields area until around 450. From around 500, an Anglo-Saxon settlement known as Lundenwic developed in the same area, slightly to the west of the old Roman city. By about 680, it had revived sufficiently to become a major port, although there is little evidence of large-scale production of goods. From the 820s the town declined because of repeated Viking invasions. There are three recorded Viking assaults on London; two of which were successful in 851 and 886 AD, although they were defeated during the attack of 994 AD.

By the late 7th century, what was a main function of Lundenwic?
Answer: a major port

Problem: The Greek men's national volleyball team has won two bronze medals, one in the European Volleyball Championship and another one in the European Volleyball League, a 5th place in the Olympic Games and a 6th place in the FIVB Volleyball Men's World Championship.

Iraklis have also seen significant success in European competitions, having been three times runners-up of the CEV Champions League.
The Greek Men's national volleyball team came in what place in the Olympic games?
The answer is the following: 5th

Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932. Francois Isaac de Rivaz built the first de Rivaz engine, an internal combustion engine powered by a mixture of hydrogen and oxygen in 1806. Edward Daniel Clarke invented the hydrogen gas blowpipe in 1819. The Dobereiner's lamp and limelight were invented in 1823.
Who was the first to discover deuterium?
Harold Urey

Input: Chicago Cubs
The Cubs successfully defended their National League Central title in 2008, going to the postseason in consecutive years for the first time since 190608. The offseason was dominated by three months of unsuccessful trade talks with the Orioles involving 2B Brian Roberts, as well as the signing of Chunichi Dragons star Kosuke Fukudome. The team recorded their 10,000th win in April, while establishing an early division lead. Reed Johnson and Jim Edmonds were added early on and Rich Harden was acquired from the Oakland Athletics in early July. The Cubs headed into the All-Star break with the N.L.'s best record, and tied the league record with eight representatives to the All-Star game, including catcher Geovany Soto, who was named Rookie of the Year. The Cubs took control of the division by sweeping a four-game series in Milwaukee. On September 14, in a game moved to Miller Park due to Hurricane Ike, Zambrano pitched a no-hitter against the Astros, and six days later the team clinched by beating St. Louis at Wrigley. The club ended the season with a 9764 record and met Los Angeles in the NLDS. The heavily favored Cubs took an early lead in Game 1, but James Loney's grand slam off Ryan Dempster changed the series' momentum. Chicago committed numerous critical errors and were outscored 206 in a Dodger sweep, which provided yet another sudden ending.

Who pitched a no-hitter against the Astros on Spetember 14th?
Output: Zambrano

Input: Article: Tennessee politics, like that of most U.S. states, are dominated by the Republican and the Democratic parties. Historian Dewey W. Grantham traces divisions in the state to the period of the American Civil War: for decades afterward, the eastern third of the state was Republican and the western two thirds voted Democrat. This division was related to the state's pattern of farming, plantations and slaveholding. The eastern section was made up of yeoman farmers, but Middle and West Tennessee cultivated crops, such as tobacco and cotton, that were dependent on the use of slave labor. These areas became defined as Democratic after the war.

Now answer this question: Which crops grown in West Tennessee had required a great deal of slave labor?

Output: tobacco and cotton

Problem: Notable exceptions include the massacre of Jews and forcible conversion of some Jews by the rulers of the Almohad dynasty in Al-Andalus in the 12th century, as well as in Islamic Persia, and the forced confinement of Moroccan Jews to walled quarters known as mellahs beginning from the 15th century and especially in the early 19th century. In modern times, it has become commonplace for standard antisemitic themes to be conflated with anti-Zionist publications and pronouncements of Islamic movements such as Hezbollah and Hamas, in the pronouncements of various agencies of the Islamic Republic of Iran, and even in the newspapers and other publications of Turkish Refah Partisi."
What were walled quarters known as?
The answer is the following:
mellahs
