Article: During the development of a tree, the lower limbs often die, but may remain attached for a time, sometimes years. Subsequent layers of growth of the attaching stem are no longer intimately joined with the dead limb, but are grown around it. Hence, dead branches produce knots which are not attached, and likely to drop out after the tree has been sawn into boards.

Question: What will the lower limbs of a tree usually do during development?
Ans: die

Article: After the start of the civil war, various new telecommunications companies began to spring up in the country and competed to provide missing infrastructure. Somalia now offers some of the most technologically advanced and competitively priced telecommunications and internet services in the world. Funded by Somali entrepreneurs and backed by expertise from China, Korea and Europe, these nascent telecommunications firms offer affordable mobile phone and internet services that are not available in many other parts of the continent. Customers can conduct money transfers (such as through the popular Dahabshiil) and other banking activities via mobile phones, as well as easily gain wireless Internet access.

Question: Who funded the new telecommunications firms in Somalia?
Ans: Somali entrepreneurs

Article: Paris' disconnect with its suburbs, its lack of suburban transportation in particular, became all too apparent with the Paris agglomeration's growth. Paul Delouvrier promised to resolve the Paris-suburbs mesentente when he became head of the Paris region in 1961: two of his most ambitious projects for the Region were the construction of five suburban villes nouvelles ("new cities") and the RER commuter train network. Many other suburban residential districts (grands ensembles) were built between the 1960s and 1970s to provide a low-cost solution for a rapidly expanding population: these districts were socially mixed at first, but few residents actually owned their homes (the growing economy made these accessible to the middle classes only from the 1970s). Their poor construction quality and their haphazard insertion into existing urban growth contributed to their desertion by those able to move elsewhere and their repopulation by those with more limited possibilities.

Question: When did Paul Delouvrier become the head of the Paris region?
Ans: 1961

Article: George Gipp was the school's legendary football player during 191620. He played semiprofessional baseball and smoked, drank, and gambled when not playing sports. He was also humble, generous to the needy, and a man of integrity. It was in 1928 that famed coach Knute Rockne used his final conversation with the dying Gipp to inspire the Notre Dame team to beat the Army team and "win one for the Gipper." The 1940 film, Knute Rockne, All American, starred Pat O'Brien as Knute Rockne and Ronald Reagan as Gipp. Today the team competes in Notre Dame Stadium, an 80,795-seat stadium on campus. The current head coach is Brian Kelly, hired from the University of Cincinnati on December 11, 2009. Kelly's record in midway through his sixth season at Notre Dame is 5221. In 2012, Kelly's Fighting Irish squad went undefeated and played in the BCS National Championship Game. Kelly succeeded Charlie Weis, who was fired in November 2009 after five seasons. Although Weis led his team to two Bowl Championship Series bowl games, his overall record was 3527, mediocre by Notre Dame standards, and the 2007 team had the most losses in school history. The football team generates enough revenue to operate independently while $22.1 million is retained from the team's profits for academic use. Forbes named the team as the most valuable in college football, worth a total of $101 million in 2007.

Question: How many seats are in Notre Dame Stadium?
Ans:
80,795
