Question: Passage: The most precise timekeeping device of the ancient world was the water clock, or clepsydra, one of which was found in the tomb of Egyptian pharaoh Amenhotep I (15251504 BC). They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea (southeastern Mesopotamia) regularly maintained timekeeping records as an essential part of their astronomical observations. Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. In the 11th century, Chinese inventors and engineers invented the first mechanical clocks driven by an escapement mechanism.

Answer: What device was invented by the ancient Greeks?

Question: Passage: The managing director of London Weekend Television (LWT), Greg Dyke, met with the representatives of the "big five" football clubs in England in 1990. The meeting was to pave the way for a break away from The Football League. Dyke believed that it would be more lucrative for LWT if only the larger clubs in the country were featured on national television and wanted to establish whether the clubs would be interested in a larger share of television rights money. The five clubs decided it was a good idea and decided to press ahead with it; however, the league would have no credibility without the backing of The Football Association and so David Dein of Arsenal held talks to see whether the FA were receptive to the idea. The FA did not enjoy an amicable relationship with the Football League at the time and considered it as a way to weaken the Football League's position.

Answer:
Who is the managing director of The Football League?
