Problem: Green:

Green can communicate safety to proceed, as in traffic lights. Green and red were standardized as the colors of international railroad signals in the 19th century. The first traffic light, using green and red gas lamps, was erected in 1868 in front of the Houses of Parliament in London. It exploded the following year, injuring the policeman who operated it. In 1912, the first modern electric traffic lights were put up in Salt Lake City, Utah. Red was chosen largely because of its high visibility, and its association with danger, while green was chosen largely because it could not be mistaken for red. Today green lights universally signal that a system is turned on and working as it should. In many video games, green signifies both health and completed objectives, opposite red.

When was the first traffic light erected?

A: 1868

Problem: The CD was planned to be the successor of the gramophone record for playing music, rather than primarily as a data storage medium. From its origins as a musical format, CDs have grown to encompass other applications. In 1983, following the CD's introduction, Immink and Braat presented the first experiments with erasable compact discs during the 73rd AES Convention. In June 1985, the computer-readable CD-ROM (read-only memory) and, in 1990, CD-Recordable were introduced, also developed by both Sony and Philips. Recordable CDs were a new alternative to tape for recording music and copying music albums without defects introduced in compression used in other digital recording methods. Other newer video formats such as DVD and Blu-ray use the same physical geometry as CD, and most DVD and Blu-ray players are backward compatible with audio CD.
Who created the DVD and Blu-ray discs?

Burke's religious writing comprises published works and commentary on the subject of religion. Burke's religious thought was grounded in the belief that religion is the foundation of civil society. He sharply criticised deism and atheism, and emphasised Christianity as a vehicle of social progress. Born in Ireland to a Catholic mother and a Protestant father, Burke vigorously defended the Anglican Church, but also demonstrated sensitivity to Catholic concerns. He linked the conservation of a state (established) religion with the preservation of citizens' constitutional liberties and highlighted Christianity's benefit not only to the believer's soul, but also to political arrangements.
What did Burke think was the foundation of society?
A: religion

Context and question: Since the start of the 199495 season, the FA Cup has been sponsored. However, to protect the identity of the competition, the sponsored name has always included 'The FA Cup' in addition to the sponsor's name, unlike sponsorship deals for the League Cup where the word 'cup' is preceded by only the sponsor's name. Sponsorship deals run for four years, though as in the case of E.ON one-year extensions may be agreed. Emirates airline is the sponsor from 2015 to 2018, renaming the competition as 'The Emirates FA Cup', unlike previous editions, which included 'The FA Cup in association with E.ON' and 'The FA Cup with Budweiser'.
How long does the sponsor remain?
Answer: Sponsorship deals run for four years

Question: In 2003 the FA took the decision to permanently use the new Wembley for semi-finals to recoup debts in financing the new stadium. This was controversial, with the move seen as both unfair to fans of teams located far from London, as well as taking some of the prestige away from a Wembley final. In defending the move, the FA has also cited the extra capacity Wembley offers, although the 2013 fixture between Millwall and Wigan led to the unprecedented step of placing 6,000 tickets on sale to neutral fans after the game failed to sell out. A fan poll by The Guardian in 2013 found 86% opposition to Wembley semi-finals.
Is there an answer to this question: Do the people of London agree with this action?

Answer: the move seen as both unfair to fans of teams located far from London

The phrase is usually used in local political debates, in polemic writing or in private conversations. It is rarely used by politicians themselves in a public context, although at certain times in Canadian history political parties have used other similarly loaded imagery. In the 1988 federal election, the Liberals asserted that the proposed Free Trade Agreement amounted to an American takeover of Canadanotably, the party ran an ad in which Progressive Conservative (PC) strategists, upon the adoption of the agreement, slowly erased the Canada-U.S. border from a desktop map of North America. Within days, however, the PCs responded with an ad which featured the border being drawn back on with a permanent marker, as an announcer intoned "Here's where we draw the line."
Who erased the border in political parties?
A:
