The problem: Answer a question about this article:
The name of the winning team is engraved on the silver band around the base as soon as the final has finished, in order to be ready in time for the presentation ceremony. This means the engraver has just five minutes to perform a task which would take twenty under normal conditions, although time is saved by engraving the year on during the match, and sketching the presumed winner. During the final, the trophy wears is decorated with ribbons in the colours of both finalists, with the loser's ribbons being removed at the end of the game. Traditionally, at Wembley finals, the presentation is made at the Royal Box, with players, led by the captain, mounting a staircase to a gangway in front of the box and returning by a second staircase on the other side of the box. At Cardiff the presentation was made on a podium on the pitch.
how long does the engraved have from start to finish?

Several countries have established their national churches, linking the ecclesiastical structure with the state. Jurisdictions where a Protestant denomination has been established as a state religion include several Nordic countries; Denmark (including Greenland), the Faroe Islands (its church being independent since 2007), Iceland and Norway have established Evangelical Lutheran churches. Tuvalu has the only established church in Reformed tradition in the world, while Tongain the Methodist tradition. The Church of England is the officially established religious institution in England, and also the Mother Church of the worldwide Anglican Communion.
How long has the Faroe Islands church been independent?
****
The answer: since 2007

Bell was connected with the eugenics movement in the United States. In his lecture Memoir upon the formation of a deaf variety of the human race presented to the National Academy of Sciences on November 13, 1883 he noted that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that couples where both parties were deaf should not marry. However, it was his hobby of livestock breeding which led to his appointment to biologist David Starr Jordan's Committee on Eugenics, under the auspices of the American Breeders' Association. The committee unequivocally extended the principle to man. From 1912 until 1918 he was the chairman of the board of scientific advisers to the Eugenics Record Office associated with Cold Spring Harbor Laboratory in New York, and regularly attended meetings. In 1921, he was the honorary president of the Second International Congress of Eugenics held under the auspices of the American Museum of Natural History in New York. Organisations such as these advocated passing laws (with success in some states) that established the compulsory sterilization of people deemed to be, as Bell called them, a "defective variety of the human race." By the late 1930s, about half the states in the U.S. had eugenics laws, and California's compulsory sterilization law was used as a model for that of Nazi Germany.
What did Bell like to do that led to his involvement with eugenics?
****
The answer: livestock breeding

The problem: Answer a question about this article:
Off-grid PV systems have traditionally used rechargeable batteries to store excess electricity. With grid-tied systems, excess electricity can be sent to the transmission grid, while standard grid electricity can be used to meet shortfalls. Net metering programs give household systems a credit for any electricity they deliver to the grid. This is handled by 'rolling back' the meter whenever the home produces more electricity than it consumes. If the net electricity use is below zero, the utility then rolls over the kilowatt hour credit to the next month. Other approaches involve the use of two meters, to measure electricity consumed vs. electricity produced. This is less common due to the increased installation cost of the second meter. Most standard meters accurately measure in both directions, making a second meter unnecessary.
How is the credit to households accomplished?
