Problem: Aircraft carrier:

Key personnel involved in the flight deck include the shooters, the handler, and the air boss. Shooters are naval aviators or Naval Flight Officers and are responsible for launching aircraft. The handler works just inside the island from the flight deck and is responsible for the movement of aircraft before launching and after recovery. The "air boss" (usually a commander) occupies the top bridge (Primary Flight Control, also called primary or the tower) and has the overall responsibility for controlling launch, recovery and "those aircraft in the air near the ship, and the movement of planes on the flight deck, which itself resembles a well-choreographed ballet." The captain of the ship spends most of his time one level below primary on the Navigation Bridge. Below this is the Flag Bridge, designated for the embarked admiral and his staff.

Where does the captain of the ship spend most of his time?
---
A: on the Navigation Bridge


Problem: High-voltage AC overhead systems are not only for standard gauge national networks. The meter gauge Rhaetian Railway (RhB) and the neighbouring Matterhorn Gotthard Bahn (MGB) operate on 11 kV at 16.7 Hz frequency. Practice has proven that both Swiss and German 15 kV trains can operate under these lower voltages. The RhB started trials of the 11 kV system in 1913 on the Engadin line (St. Moritz-Scuol/Tarasp). The MGB constituents Furka-Oberalp-Bahn (FO) and Brig-Visp-Zermatt Bahn (BVZ) introduced their electric services in 1941 and 1929 respectively, adopting the already proven RhB system.
Who started trials of the 111kV system?

The expression of genes encoded in DNA begins by transcribing the gene into RNA, a second type of nucleic acid that is very similar to DNA, but whose monomers contain the sugar ribose rather than deoxyribose. RNA also contains the base uracil in place of thymine. RNA molecules are less stable than DNA and are typically single-stranded. Genes that encode proteins are composed of a series of three-nucleotide sequences called codons, which serve as the "words" in the genetic "language". The genetic code specifies the correspondence during protein translation between codons and amino acids. The genetic code is nearly the same for all known organisms.:4.1
How does the expression of genes encoded in DNA begin?
A: by transcribing the gene into RNA


Context and question: The New Haven Green is the site of many free music concerts, especially during the summer months. These have included the New Haven Symphony Orchestra, the July Free Concerts on the Green in July, and the New Haven Jazz Festival in August. The Jazz Festival, which began in 1982, is one of the longest-running free outdoor festivals in the U.S., until it was canceled for 2007. Headliners such as The Breakfast, Dave Brubeck, Ray Charles and Celia Cruz have historically drawn 30,000 to 50,000 fans, filling up the New Haven Green to capacity. The New Haven Jazz Festival was revived in 2008 and has been sponsored since by Jazz Haven.
When did the first Jazz Festival made it debut?
Answer: 1982


Question: The rugby union team The Rock is the Eastern Canadian entry in the Americas Rugby Championship. The Rock play their home games at Swilers Rugby Park, as did the Rugby Canada Super League champions for 2005 and 2006, the Newfoundland Rock. The city hosted a Rugby World Cup qualifying match between Canada and the USA on 12 August 2006, where the Canadians heavily defeated the USA 56–7 to qualify for the 2007 Rugby World Cup finals in France. The 2007 age-grade Rugby Canada National Championship Festival was held in the city.
Is there an answer to this question: Who hosted the qualifying match between Canada and Europe?

Answer: unanswerable

In 2012, the AFL celebrated its silver anniversary for its 25th season of operations. The season kicked off on March 9, 2012. The Tulsa Talons moved to San Antonio, Texas and Jeffrey Vinik became owner of the Tampa Bay Storm. The Dallas Vigilantes were left off the schedule for the 2012 season with no announcement from the management, raising speculations that either the team had suspended operations for the season or was ceasing operations altogether. (Apparently the latter was the case as the organization did not field a team for the 2013 season or any subsequent one either.) Like the National Football League, the AFL postponed the free agency period to October 31 due to Hurricane Sandy.
Who bought the Tampa Bay Storm in 2012?
A:
Jeffrey Vinik
