Problem: The tour in March 1987[citation needed] of Knuckles, Jefferson, Fingers Inc. (Heard) and Adonis as the DJ International Tour boosted house in the UK. Following the number-one success of MARRS' "Pump Up The Volume" in October, the years 1987 to 1989 also saw UK acts such as The Beatmasters, Krush, Coldcut, Yazz, Bomb The Bass, S-Express, and Italy's Black Box opening the doors to a house music onslaught on the UK charts. Early British house music quickly set itself apart from the original Chicago house sound;[citation needed] many of the early hits were based on sample montage, rap was often used for vocals (far more than in the US),[citation needed] and humor was frequently an important element.
What was the name of MARRS's number-one single in October 1989?

Problem: Britain's first use of brass occurred around the 3rd2nd century BC. In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600. Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD; it proceeded at a much slower rate on other continents. Copper burial ornamentals from the 15th century have been uncovered, but the metal's commercial production did not start until the early 20th century.
What country stopped a strong copper production in 1000 AD?

Problem: The women's division of professional wrestling has maintained a recognized world champion since 1937, when Mildred Burke won the original World Women's title. She then formed the World Women's Wrestling Association in the early 1950s and recognized herself as the first champion, although the championship would be vacated upon her retirement in 1956. The NWA, however, ceased to acknowledge Burke as their Women's World champion in 1954, and instead acknowledged June Byers as champion after a controversial finish to a high-profile match between Burke and Byers that year. Upon Byers' retirement in 1964, The Fabulous Moolah, who won a junior heavyweight version of the NWA World Women's Championship (the predecessor to the WWE's Women's Championship) in a tournament back in 1958, was recognized by most NWA promoters as champion by default.
What did Mildred Burke form?
