An independent test in 2009 uploaded multiple versions of the same song to YouTube, and concluded that while the system was "surprisingly resilient" in finding copyright violations in the audio tracks of videos, it was not infallible. The use of Content ID to remove material automatically has led to controversy in some cases, as the videos have not been checked by a human for fair use. If a YouTube user disagrees with a decision by Content ID, it is possible to fill in a form disputing the decision. YouTube has cited the effectiveness of Content ID as one of the reasons why the site's rules were modified in December 2010 to allow some users to upload videos of unlimited length.
What was the ultimate view of Content ID's performance after a 2009 test?
****
The answer: surprisingly resilient

Before the latter half of the 18th century, grain, timber and then coal were Plymouth's main imports. During this time the real source of wealth was from the neighbouring town of Plymouth Dock (renamed in 1824 to Devonport) and the major employer in the entire region was the dockyard. The Three Towns conurbation of Plymouth, Stonehouse and Devonport enjoyed some prosperity during the late 18th and early 19th century and were enriched by a series of neo-classical urban developments designed by London architect John Foulston. Foulston was important for both Devonport and Plymouth and was responsible for several grand public buildings, many now destroyed, including the Athenaeum, the Theatre Royal and Royal Hotel, and much of Union Street.
What architect was noted for his neoclassical designs in Plymouth?
****
The answer: John Foulston

Although the Arenafootball2 league played its tenth season in 2009, a conference call in December 2008 resulted in enough votes from owners and cooperation from the AFLPA for the AFL to suspend the entire 2009 season in order to create "a long-term plan to improve its economic model". In doing so, the AFL became the second sports league to cancel an entire season, after the National Hockey League cancelled the 2004-05 season because of a lockout. The AFL also became the third sports league to lose its postseason (the first being Major League Baseball, which lost its postseason in 1994 because of a strike). Efforts to reformat the league's business model were placed under the leadership of Columbus Destroyers owner Jim Renacci and interim commissioner Policy.
In what month and year was it decided to suspend the 2009 Arena Football League season?
****
The answer:
December 2008
