Question: Passage: Seattle was awarded a Major League Baseball franchise, the Seattle Pilots, in 1969. The team played at Sick's Stadium in Mount Baker for one season before relocating to Milwaukee and becoming the Milwaukee Brewers. The city, county, and state governments sued the league and was offered a second expansion team, the Seattle Mariners, who began play at the Kingdome in 1977. The Mariners struggled in the stadium and moved to a purpose-built baseball stadium, T-Mobile Park (formerly Safeco Field), in 1999. The Mariners have never reached a World Series and only appeared in the MLB playoffs four times, all between 1995 and 2001, despite having Hall of Fame players and candidates like Ken Griffey Jr., Randy Johnson, Ichiro, and Alex Rodriguez. The team tied the all-time single regular season wins record in 2001 with 116 wins. Since 2001, the Mariners have failed to qualify for the playoffs—the longest active postseason drought in North American sports, at 17 seasons.
From 1967 to 2008 Seattle was also home to a National Basketball Association (NBA) franchise: the Seattle SuperSonics, who were the 1978–79 NBA champions. The SuperSonics relocated to Oklahoma City and became the Oklahoma City Thunder for the 2008–09 season.The Major League Baseball All-Star Game was held in Seattle twice, first at the Kingdome in 1979 and again at Safeco Field in 2001. The NBA All-Star Game was also held in Seattle twice: the first in 1974 at the Seattle Center Coliseum and the second in 1987 at the Kingdome.Seattle also boasts two collegiate sports teams based at the University of Washington and Seattle University, both competing in NCAA Division I for various sports. The University of Washington's athletic program, nicknamed the Huskies, competes in the Pac-12 Conference, and Seattle University's athletic program, nicknamed the Redhawks, mostly competes in the Western Athletic Conference. The Huskies teams use several facilities, including the 70,000-seat Husky Stadium for football and the Hec Edmundson Pavilion for basketball and volleyball. The two schools have basketball and soccer teams that compete against each other in non-conference games and have formed a local rivalry due to their sporting success.The Seattle Thunderbirds hockey team plays in the Canadian major-junior Western Hockey League and are based in the Seattle suburb of Kent. Seattle successfully applied for a new expansion team with the National Hockey League, which will make its first appearance in 2021. Seattle plans to renovate KeyArena to use for the possible NHL team. On March 1, 2018, a ticket drive began to gauge interests in season ticket deposits. Oak View reported that their initial goal of 10,000 deposits was surpassed in 12 minutes, and that they received 25,000 deposits in 75 minutes. 
Question: What arena will the city that held the NBA All-Star game twice renovate for possible use for an NHL expansion team?

Answer: KeyArena.


Question: Passage: Bach's early cantatas are Choralkonzerte (chorale concertos) in the style of the 17th century, different from the recitative and aria cantata format associated with Neumeister that Bach started to use for church cantatas in 1714. Wolff points out the relation of Bach's early cantatas to works by Dieterich Buxtehude, with whom Bach had studied in Lübeck. Christ lag in Todes Banden shows similarities to a composition of Johann Pachelbel based on the same Easter chorale. Although there is no evidence that Bach and Pachelbel met, Bach grew up in Thuringia while Pachelbel was based in the same region, and Bach's elder brother and teacher Johann Christoph Bach studied with Pachelbel in Erfurt. Another of Pachelbel's works appears to be referenced in the early Bach cantata, Nach dir, Herr, verlanget mich, BWV 150, and there has been recent speculation that Bach wanted to pay tribute to Pachelbel after his death in 1706.The texts for the early cantatas were drawn mostly from biblical passages and hymns. Features characteristic of his later cantatas, such as recitatives and arias on contemporary poetry, were not yet present, although Bach may have heard them in oratorios by Buxtehude, or even earlier. Instead, these early cantatas include 17th-century elements such as motets and chorale concertos. They often begin with an instrumental sinfonia or sonata (sonatina). The following table lists the seven extant works composed by Bach until 1708, when he moved on to the Weimar court.
Bach uses the limited types of instruments at his disposal for unusual combinations, such as two recorders and two viole da gamba in the funeral cantata Gottes Zeit ist die allerbeste Zeit, also known as Actus Tragicus. He uses instruments of the continuo group as independent parts, such as a cello in Nach dir, Herr, verlanget mich and a bassoon in Der Herr denket an uns. The cantata for the inauguration of a town council is richly scored for trumpets, woodwinds and strings. Wolff notes:
The overall degree of mastery by which these early pieces compare favourably with the best church compositions from the first decade of the eighteenth century ... proves that the young Bach did not confine himself to playing organ and clavier, but, animated by his Buxtehude visit, devoted considerable time and effort to vocal composition. The very few such early works that exist, each a masterpiece in its own right, must constitute a remnant only ... of a larger body of similar compositions.
The Bach scholar Richard D. P. Jones notes in The Creative Development of Johann Sebastian Bach:
"His remarkable flair for text illustration is evident even in the early cantatas, particularly the two finest of them, the Actus tragicus, BWV 106, and Christ lag in Todes Banden, BWV 4. We already sense a powerful mind behind the notes in the motivic unity of the early cantatas, in the use of reprise to bind their mosaic forms together ...". 
Question: What often begin with an instrumental sinfonia or sonata?

Answer: cantatas.


Question: Passage: Because of the 1932 Byrd Road Act, the state government controls most of Virginia's roads, instead of a local county authority as is usual in other states. As of 2018, the Virginia Department of Transportation owns and operates 57,867 miles (93,128 km) of the total 70,105 miles (112,823 km) of roads in the state, making it the third largest state highway system in the United States. Although the Washington Metropolitan Area, which includes Northern Virginia, has the second highest rate of traffic congestion in the nation, Virginia as a whole has the 21st-lowest rate of congestion and the average commute time is 26.9 minutes. Virginia hit peak car usage before the year 2000, making it one of the first such states.
Virginia has Amtrak passenger rail service along several corridors, and Virginia Railway Express (VRE) maintains two commuter lines into Washington, D.C. from Fredericksburg and Manassas. VRE is one of the nation's fastest growing commuter rail services, handling nearly 20,000 passengers a day. Arlington accounted for 40% of Virginia's public transit trips as of 2013, with most of that being from the Washington Metro transit system, which also serves Alexandria  and communities in Fairfax County along I-66. The system is currently expanding west into additional areas of Loudoun County. Major freight railroads in Virginia include Norfolk Southern and CSX Transportation, the former of which is headquartered in Norfolk. Commuter buses include the Fairfax Connector and the Shenandoah Valley Commuter Bus. The Virginia Department of Transportation operates several free ferries throughout Virginia, the most notable being the Jamestown-Scotland ferry which crosses the James River in Surry County.Virginia has five major airports: Washington Dulles International and Reagan Washington National in Northern Virginia, both of which handle over 20 million passengers a year; Richmond International; and Newport News/Williamsburg International Airport and Norfolk International serving the Hampton Roads area. Several other airports offer limited commercial passenger service, and sixty-six public airports serve the state's aviation needs. The Virginia Port Authority's main seaports are those in Hampton Roads, which carried 17,726,251 short tons (16,080,984 t) of bulk cargo in 2007, the sixth most of United States ports. The Eastern Shore of Virginia is the site of Wallops Flight Facility, a rocket testing center owned by NASA, and the Mid-Atlantic Regional Spaceport, a commercial spaceport. Space tourism is also offered through Vienna-based Space Adventures. 
Question: Which freight railroad is headquartered in Norfolk?

Answer:
Norfolk Southern.
