Ex Input:
Passage: Richie Donovan works as a professional thief for Groznyi, a wealthy businessman, to pay off his debt for being smuggled into the U.S. as a child. He pulls off an initially successful diamond heist, but it is botched when he is involved in two separate car accidents. He is given one last chance to pay off his debt by going to Russia to steal a priceless antique cross, locked in a safe in a Moscow penthouse apartment. Richie and his Russian accomplices, brothers Peter and Yuri, recover the cross; but their elevator becomes stuck on the uncompleted 13th floor. Believing the police have stopped the elevator, the thieves take their fellow passengers hostage to negotiate an escape. They agree to send one hostage down; but, when the elevator doors open on the ground floor, the hostage has mysteriously been beheaded. 
The remaining hostages quickly divide into two groups: a Christian group consisting of Sonya, Helena and Katerina, who are later joined by Yuri, and another group consisting of nerdy Dmitry, beautiful Anna, and incompetent security guard Boris.
In the confusion, the Christian group seizes firearms and takes control, shooting Peter. Katerina is sent to stand guard over Richie and the remainder of the hostages, while Sonya takes Yuri to a chamber where he is to sacrificed by a wild man in armor named Alex. Yuri escapes, but he is impaled by one of Alex's traps, complete with disco music and lighting. In his rage, Alex kills Katerina, allowing Richie and the hostages to escape. They discover Alex's lair, where he has been watching everyone using security cameras. A photo reveals that Alex is the twin brother of Sonya, and they both believe themselves to be descendants of Ivan the Terrible. The group splits when Richie and Anna decide to chase after Alex, while Boris and Dmitry prefer to rig the room with various traps they have constructed and wait for Alex to come to them. 
Question: Who are the people who think the authorities are responsible for the elevator stopping, leading them to take hostages?

Ex Output:
Richie.

Passage: From the colonizers' perspective, Carabane's position at the mouth of the river was an undeniable asset. In the 20th and 21st centuries, in terms of trade and tourism issues, this location is more of a disadvantage because it effectively separates the island from the rest of the country.
While a direct route by sea has not been available since the sinking of the Joola, the traveller from Dakar may use various other means of transportation in order to arrive in Basse Casamance. Some national roads connect to Ziguinchor, down the N1 to Kaolack. The N4 and N5 roads cross the Gambia (both the country and the river), the former running through Nioro du Rip to Farafenni, and the latter crossing the river to Banjul. The two roads merge in Bignona before descending to Ziguinchor. However, traffic is forbidden on both roads between 7 p.m. and 10 a.m., and the routes are subject to frequent accidents and constant demining operations. Alternatively, it is possible to travel by plane to the airport in Ziguinchor or Cap Skirring, or to travel by boat to one of these locations. Reaching Carabane from either town is relatively straightforward.By boat, the distance between Dakar and Carabane is 265 kilometres (143 nmi), although Ziguinchor is only 48 kilometres (30 mi) away. Before the launch of the Joola, other boats, mostly well-worn ones, made the connection: first Cap Skirring, then the Casamance Express, and then Island Karabane. In January 1991, a brand new ferry went into operation. Like its predecessors, it connected Dakar to Ziguinchor, stopping near Carabane where canoes could reach the island. On September 26, 2002, 180 extra passengers boarded the already overloaded ship at this stop, and a few hours later, the Joola sank. For security reasons, the Joola's successor, the Wilis, stopped calling at Carabane, to the great displeasure of the inhabitants. Tourists became rare after that, and from time to time, inhabitants of the island found it necessary to move to Dakar or Ziguinchor. Significant modifications to the MV Aline Sitoe Diatta, which replaced the Wilis in March 2008, were considered to allow it to stop safely at the island, and the construction of a berth was announced. Souleymane Ndéné Ndiaye, who later became Prime Minister of Senegal, laid the first stone of the berth in July 2008, and the entire construction project was financed by the Senegalese government at an estimated cost of 12 billion West African CFA francs. On April 26, 2014, the MV Aline Sitoe Diatta stopped at the Carabane berth for the first time, improving transportation for locals and tourists. As of 2015, the ferry stops at Carabane four times each week in the middle of its trips between Dakar and Ziguinchor. 
Question: What is the name of the ferry that, since 2015, stops at Carabane four times each week in the middle of its trips between Dakar and Ziguinchor?

Ex Output:
MV Aline Sitoe Diatta.

Passage: Another letter to The New York Times blamed the shark infestation on the maneuvers of German U-boats near America's East Coast. The anonymous writer claimed, "These sharks may have devoured human bodies in the waters of the German war zone and followed liners to this coast, or even followed the Deutschland herself, expecting the usual toll of drowning men, women, and children." The writer concluded, "This would account for their boldness and their craving for human flesh."Decades later, there is no consensus among researchers over Murphy and Lucas's investigation and findings. Richard G. Fernicola published two studies of the event, and notes that "there are many theories behind the New Jersey attacks," and all are inconclusive. Researchers such as Thomas Helm, Harold W. McCormick, Thomas B. Allen, William Young, Jean Campbell Butler, and Michael Capuzzo generally agree with Murphy and Lucas. However, the National Geographic Society reported in 2002 that "some experts are suggesting that the great white may not in fact be responsible for many of the attacks pinned on the species. These people say the real culprit behind many of the reported incidents—including the famous 1916 shark attacks in New Jersey that may have served as inspiration for Jaws—may be the lesser known bull shark."Biologists George A. Llano and Richard Ellis suggest that a bull shark could have been responsible for the fatal Jersey Shore attacks. Bull sharks swim from the ocean into freshwater rivers and streams and have attacked people around the world. In his book Sharks: Attacks on Man (1975), Llano writes,
One of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea. Elsewhere in the book are accounts of well-documented shark-human interactions at Ahwaz, Iran, which is 90 miles (140 km) upriver from the sea. It may also be of interest to note that sharks live in Lake Nicaragua, a fresh-water body, and in 1944 there was a bounty offered for dead freshwater sharks, as they had "killed and severely injured lake bathers recently."
Ellis points out that the great white "is an oceanic species, and Schleisser's shark was caught in the ocean. To find it swimming in a tidal creek is, to say the least, unusual, and may even be impossible. The bull shark, however, is infamous for its freshwater meanderings, as well as for its pugnacious and aggressive nature."  He admits that "the bull shark is not a common species in New Jersey waters, but it does occur more frequently than the white."In an interview with Michael Capuzzo, ichthyologist George H. Burgess surmises, "The species involved has always been doubtful and likely will continue to generate spirited debate." Burgess, however, does not discount the great white:. 
Question: What is the first name of the person who does not discount the great white?

Ex Output:

George.
