Passage: Young couple Richard and Alex want what everyone wants: career, kids and a gorgeous home in L.A. But it all seems so impossible until they crash a party at Edendale, their dream house, owned by Jake and Chloe, who are hosting a fundraiser for the orphans of Bhutan.  Richard and Alex hit it off with the hosts, and while house-sitting for them, discover a secret room filled with a million in cash.
When Jake and Chloe die in a "rickshaw accident" overseas, Richard and Alex worry the cash might not go to the orphans, so they break into Edendale and take the money. They earnestly try to donate the money to Jigme Wangchuck, the deputy ambassador of the Embassy of Bhutan, and his assistant Priti Khagda.  But the Embassy officials, thinking they're being set up, refuse the money.  So Richard and Alex deposit the cash, find another charity, and end up writing a check to "The Porpoise Purpose," headed by Stuart Hendron and his assistant Olivier.
Just then, they learn from their Realtor, Logan, (Tom Lenk), that Edendale is now on the market.  They really want it but have given the money to the porpoise charity—so they stop payment on the check and use the money as down payment on the house, intending to repay the charity by taking out a second mortgage once escrow closes. 
Question: What is the name of the charity Richard and Alex stop payment on their check and use the money for a down payment on the house??
The Porpoise Purpose,.

Passage: Transportation in Oklahoma is generated by an anchor system of Interstate Highways, inter-city rail lines, airports, inland ports, and mass transit networks. Situated along an integral point in the United States Interstate network, Oklahoma contains three primary Interstate highways and four auxiliary Interstate Highways. In Oklahoma City, Interstate 35 intersects with Interstate 44 and Interstate 40, forming one of the most important intersections along the United States highway system.More than 12,000 miles (19,000 km) of roads make up the state's major highway skeleton, including state-operated highways, ten turnpikes or major toll roads, and the longest drivable stretch of Route 66 in the nation. In 2008, Interstate 44 in Oklahoma City was Oklahoma's busiest highway, with a daily traffic volume of 123,300 cars. In 2010, the state had the nation's third-highest number of bridges classified as structurally deficient, with nearly 5,212 bridges in disrepair, including 235 National Highway System Bridges.Oklahoma's largest commercial airport is Will Rogers World Airport in Oklahoma City, averaging a yearly passenger count of more than 3.5 million (1.7 million boardings) in 2010. Tulsa International Airport, the state's second-largest commercial airport, served more than 1.3 million boardings in 2010. Between the two, six airlines operate in Oklahoma. In terms of traffic, R. L. Jones Jr. (Riverside) Airport in Tulsa is the state's busiest airport, with 335,826 takeoffs and landings in 2008. Oklahoma has over 150 public-use airports.Oklahoma is connected to the nation's rail network via Amtrak's Heartland Flyer, its only regional passenger rail line. It currently stretches from Oklahoma City to Fort Worth, Texas, though lawmakers began seeking funding in early 2007 to connect the Heartland Flyer to Tulsa.Two inland ports on rivers serve Oklahoma: the Port of Muskogee and the Tulsa Port of Catoosa. The state's only port handling international cargo, the Tulsa Port of Catoosa is the most inland ocean-going port in the nation and ships over two million tons of cargo each year. Both ports are on the McClellan–Kerr Arkansas River Navigation System, which connects barge traffic from Tulsa and Muskogee to the Mississippi River via the Verdigris and Arkansas rivers, contributing to one of the busiest waterways in the world. 
Question: What is the name of Amtrack's rail line that currently stretches from Oklahoma City to Fort Worth Texas?
Heartland Flyer.

Passage: Impresario and author John Hollingshead, the lessee of London's Gaiety Theatre since 1868, had produced a number of successful musical burlesques and operettas there. Indeed, Hollingshead "boasted that he kept alight 'the sacred lamp of burlesque.'" Gilbert and Sullivan were each well acquainted with the Gaiety and its house artistes.  Gilbert's Robert the Devil (a burlesque of the opera Robert le Diable) had been on the programme on the theatre's opening night on 21 December 1868, with Nellie Farren in the title role, and played successfully for over 100 nights. Constance Loseby and Annie Tremaine (both of whom had roles in Thespis) were also in the cast of Robert, and Arthur Sullivan was in the audience on that opening night as one of Hollingshead's guests. It was a great success, "received with a storm of approbation". Less successfully, Gilbert had also written a play for the theatre in 1869 called An Old Score. Hollingshead would later say that the piece was "too true to nature". By late September or early October 1871, Gaiety programmes announced that "The Christmas Operatic Extravaganza will be written by W. S. Gilbert, with original music by Arthur Sullivan." There would be prominent roles for the popular comedian J. L. Toole, as well as Farren, the theatre's star "principal boy" in all of its burlesques.
How and when the pair came to collaborate on Thespis is uncertain. Gilbert was a logical choice for the assignment. With seven operas and plays premièring that year and over a dozen other burlesques, farces and extravaganzas under his belt, he was well known to London theatregoers as a comic dramatist. Sullivan, however, was at this point mainly known for his serious music. His completed music that year included the choral cantata On Shore and Sea, a suite of incidental music for Shakespeare's The Merchant of Venice, and numerous hymns, including "Onward, Christian Soldiers". He did have two comic operas to his credit, Cox and Box (1866) and The Contrabandista (1867), but the latter was four years in the past and had been unsuccessful. In September 1871, Sullivan had been engaged to conduct at The Royal National Opera, but it failed abruptly, leaving him unexpectedly without commitments. Hollingshead's offer of a role to his brother, Fred Sullivan, may have encouraged him to write the music for Thespis.The production "aroused a great deal of interest and speculation". Ironically, it had "probably the largest audience" of any Gilbert and Sullivan première, as the Gaiety was the largest of the five London theatres at which their joint works premièred. 
Question: What is the first name of the person mainly known for his serious music?

Arthur.
