Input: Consider Input: Passage: Half of Minneapolis–Saint Paul residents work in the city where they live. Most residents drive cars, but 60% of the 160,000 people working downtown commute by means other than a single person per auto. The Metropolitan Council's Metro Transit, which operates the light rail system and most of the city's buses, provides free travel vouchers through the Guaranteed Ride Home program to allay fears that commuters might otherwise be occasionally stranded if, for example, they work late hours.On January 1, 2011, the city's limit of 343 taxis was lifted.Minneapolis currently has two light rail lines and one commuter rail line. The METRO Blue Line LRT (formerly the Hiawatha Line) serves 34,000 riders daily and connects the Minneapolis–Saint Paul International Airport and Mall of America in Bloomington to downtown. Most of the line runs at surface level, although parts of the line run on elevated tracks (including the Franklin Avenue and Lake Street/Midtown stations) and approximately 2 miles (3.2 km) of the line runs underground, including the Lindbergh terminal subway station at the airport. 
Question: What is the former name of the line that has a terminal subway station at the airport?

Output: Hiawatha Line.


Input: Consider Input: 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??

Output: The Porpoise Purpose,.


Input: Consider Input: Passage: Karluk had been chosen by Pedersen and bought by Stefansson for the bargain price of US$10,000. Stefansson was advised by Pedersen that, of four ships that were available, Karluk was "the soundest and best adapted for our purpose", but Bartlett had deep reservations about her fitness for prolonged Arctic service. The ship, a 29-year-old brigantine, was 129 feet (39 m) in length with a beam of 23 feet (7.0 m). She had been built for the Aleutian fishing industry (karluk is the Aleut word for "fish") and later converted for whaling, when her bows and sides had been sheathed with 2-inch (51 mm) Australian ironwood. Despite 14 arctic whaling voyages, including six overwinterings, she had not been built to withstand sustained ice pressure, and lacked the engine power to force a passage through the ice. She did not match the expectations of Bartlett, or of many of the more experienced crew.The ship spent most of April and May 1913 undergoing repairs and refitting at the dockyard in Esquimalt. When Bartlett arrived in early June he immediately ordered further repair work. In addition to Karluk, Stefansson had purchased sight unseen a small gasoline-driven schooner, Alaska, to act as a supply ship for the Southern Party. He later added a second schooner, Mary Sachs, when the hold space in Alaska proved inadequate. In the confusion surrounding the expedition's departure, McKinlay notes, no attempt was made to align men or equipment to their appropriate ships. Thus anthropologists Henri Beuchat and Diamond Jenness, both designated for the Southern Party, found themselves sailing with Karluk, while their equipment was on board Alaska. McKinlay himself, aboard Karluk as magnetic observer, discovered that most of his equipment was with Alaska. Stefansson insisted that all would be sorted out when the ships reached their Herschel Island rendezvous. "Heaven help us all if we failed to reach Herschel Island", McKinlay wrote. 
Question: What were the names of the three ships bought by Stefansson?


Output: Karluk.
