Problem: London:

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?
---
A: a major port


Problem: The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1970. Gold coins were confiscated by Executive Order 6102 issued in 1933 by Franklin Roosevelt. The gold standard was changed to 13.71 grains (0.888 g), equivalent to setting the price of 1 troy ounce of gold at $35. This standard persisted until 1968.
How much gold in grams was one dollar equivalent to?
---
Answer: 1.505


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Oklahoma is located in a humid subtropical region. Oklahoma lies in a transition zone between humid continental climate to the north, semi-arid climate to the west, and humid subtropical climate in the central, south and eastern portions of the state. Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold, dry air from Canada, warm to hot, dry air from Mexico and the Southwestern U.S., and warm, moist air from the Gulf of Mexico. The interactions between these three contrasting air currents produces severe weather (severe thunderstorms, damaging thunderstorm winds, large hail and tornadoes) with a frequency virtually unseen anywhere else on planet Earth. An average 62 tornadoes strike the state per year—one of the highest rates in the world.
What is Oklahoma's main climate region?
A: humid subtropical


Context and question: Socially, while liberty and freedom of enterprise form the basis of its beliefs, elements of the party have wavered between what is termed "small-l liberalism" and social conservatism. Historically, Liberal Governments have been responsible for the carriage of a number of notable "socially liberal" reforms, including the opening of Australia to multiethnic immigration under Menzies and Harold Holt; Holt's 1967 Referendum on Aboriginal Rights; Sir John Gorton's support for cinema and the arts; selection of the first Aboriginal Senator, Neville Bonner, in 1971; and Malcolm Fraser's Aboriginal Land Rights Act 1976. A West Australian Liberal, Ken Wyatt, became the first Indigenous Australian elected to the House of Representatives in 2010.
Who was the first indigenous Australian elected to the House?
Answer: Ken Wyatt


Question: After the rupture of the wars with Portugal and Catalonia, the Junta changed its attitude, this time due to the exhaustion of Galicia, now involved not just in naval or oversea operations, but also in an exhausting war with the Portuguese, war which produced thousands of casualties and refugees and was heavily disturbing to the local economy and commerce. So, in the second half of the 17th century the Junta frequently denied or considerably reduced the initial petitions of the monarch, and though the tension didn't rise to the levels experienced in Portugal or Catalonia, there were frequent urban mutinies and some voices even asked for the secession of the Kingdom of Galicia.
Is there an answer to this question: War broke out with which other countries?

Answer: Portugal and Catalonia
