Problem: Elementary and secondary public schools are overseen by the North Carolina Department of Public Instruction. The North Carolina Superintendent of Public Instruction is the secretary of the North Carolina State Board of Education, but the board, rather than the superintendent, holds most of the legal authority for making public education policy. In 2009, the board's chairman also became the "chief executive officer" for the state's school system. North Carolina has 115 public school systems, each of which is overseen by a local school board. A county may have one or more systems within it. The largest school systems in North Carolina are the Wake County Public School System, Charlotte-Mecklenburg Schools, Guilford County Schools, Winston-Salem/Forsyth County Schools, and Cumberland County Schools. In total there are 2,425 public schools in the state, including 99 charter schools. North Carolina Schools were segregated until the Brown v. Board of Education trial and the release of the Pearsall Plan.
What agency oversees public schools in North Carolina?
The answer is the following: North Carolina Department of Public Instruction

Problem: Beginning in mid-2007, four major airlines, United, Continental, Delta, and Emirates, reached agreements to install iPod seat connections. The free service will allow passengers to power and charge an iPod, and view video and music libraries on individual seat-back displays. Originally KLM and Air France were reported to be part of the deal with Apple, but they later released statements explaining that they were only contemplating the possibility of incorporating such systems.
Where can people using iPods on planes view the device's interface?
The answer is the following: individual seat-back displays

Problem: In only his third career start, Kerry Wood struck out 20 batters against Houston on May 6, 1998. This is the franchise record and tied for the Major League record for the most strikeouts in one game by one pitcher (the only other pitcher to strike out 20 batters in a nine-inning game was Roger Clemens, who achieved it twice). The game is often considered the most dominant pitching performance of all time. Interestingly, Wood's first pitch struck home plate umpire Jerry Meals in the facemask. Wood then struck out the first five batters he faced. Wood hit one batter, Craig Biggio, and allowed one hit, a scratch single by Ricky Gutierrez off third baseman Kevin Orie's glove. The play was nearly scored an error, which would have given Wood a no-hitter.
When did Kerry Wood strike out 20 batters against Houston?
The answer is the following: May 6, 1998
