The problem: Answer a question about this article:
After the development of the large London Porter breweries in the 18th century, the trend grew for pubs to become tied houses which could only sell beer from one brewery (a pub not tied in this way was called a Free house). The usual arrangement for a tied house was that the pub was owned by the brewery but rented out to a private individual (landlord) who ran it as a separate business (even though contracted to buy the beer from the brewery). Another very common arrangement was (and is) for the landlord to own the premises (whether freehold or leasehold) independently of the brewer, but then to take a mortgage loan from a brewery, either to finance the purchase of the pub initially, or to refurbish it, and be required as a term of the loan to observe the solus tie.
In what century did the habit arise of pubs selling beer from only one brewery?

The answer: 18th

When Nike took over from Adidas as Arsenal's kit provider in 1994, Arsenal's away colours were again changed to two-tone blue shirts and shorts. Since the advent of the lucrative replica kit market, the away kits have been changed regularly, with Arsenal usually releasing both away and third choice kits. During this period the designs have been either all blue designs, or variations on the traditional yellow and blue, such as the metallic gold and navy strip used in the 200102 season, the yellow and dark grey used from 2005 to 2007, and the yellow and maroon of 2010 to 2013. As of 2009, the away kit is changed every season, and the outgoing away kit becomes the third-choice kit if a new home kit is being introduced in the same year.
Since what year has the away kit been changed every year?
****
The answer: 2009

In testimony before the Senate Committee on Commerce, Science, and Transportation on June 3, 2008, former director of the CFTC Division of Trading & Markets (responsible for enforcement) Michael Greenberger specifically named the Atlanta-based IntercontinentalExchange, founded by Goldman Sachs, Morgan Stanley and BP as playing a key role in speculative run-up of oil futures prices traded off the regulated futures exchanges in London and New York. However, the IntercontinentalExchange (ICE) had been regulated by both European and U.S. authorities since its purchase of the International Petroleum Exchange in 2001. Mr Greenberger was later corrected on this matter.
Where are regulated future exchanges located?
