Problem: Premier League:

The TV rights agreement between the Premier League and Sky has faced accusations of being a cartel, and a number of court cases have arisen as a result. An investigation by the Office of Fair Trading in 2002 found BSkyB to be dominant within the pay TV sports market, but concluded that there were insufficient grounds for the claim that BSkyB had abused its dominant position. In July 1999 the Premier League's method of selling rights collectively for all member clubs was investigated by the UK Restrictive Practices Court, who concluded that the agreement was not contrary to the public interest.

What did the Office of Fair Trading decide regarding the claim that Sky abuses their position in 2002.

A: Office of Fair Trading in 2002 found BSkyB to be dominant within the pay TV sports market, but concluded that there were insufficient grounds for the claim

Problem: Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.
What element was used in the production of wrought iron?
---
Answer: oxygen

Context and question: The name Ashkenazi derives from the biblical figure of Ashkenaz, the first son of Gomer, son of Khaphet, son of Noah, and a Japhetic patriarch in the Table of Nations (Genesis 10). The name of Gomer has often been linked to the ethnonym Cimmerians. Biblical Ashkenaz is usually derived from Assyrian Askuza (cuneiform Askuzai/Iskuzai), a people who expelled the Cimmerians from the Armenian area of the Upper Euphrates, whose name is usually associated with the name of the Scythians. The intrusive n in the Biblical name is likely due to a scribal error confusing a waw with a nun .
The name of Gomer has often been linked to what ethnonym?
Answer: Cimmerians

There is confusion currently as to the name of the eldest Vinaccia luthier who first ran the shop. His name has been put forth as Gennaro Vinaccia (active c. 1710 to c. 1788) and Nic. Vinaccia. His son Antonio Vinaccia was active c. 1734 to c. 1796. An early extant example of a mandolin is one built by Antonio Vinaccia in 1759, which resides at the University of Edinburgh. Another is by Giuseppe Vinaccia, built in 1893, is also at the University of Edinburgh. The earliest extant mandolin was built in 1744 by Antonio's son, Gaetano Vinaccia.
