[EX Q]: Passage: Louis Salinger, an Interpol detective, and Eleanor Whitman, an Assistant District Attorney from Manhattan, are investigating the International Bank of Business and Credit, which funds activities such as money laundering, terrorism, arms trading, and the destabilization of governments. Salinger's and Whitman's investigation takes them from Berlin to Milan, where the IBBC assassinates Umberto Calvini, an arms manufacturer who is an Italian prime ministerial candidate. The bank's assassin diverts suspicion to a local assassin with political connections, who is promptly killed by a corrupt policeman. Salinger and Whitman get a lead on the second assassin, but the corrupt policeman shows up again and orders them out of the country. At the airport they are able to check the security camera footage for clues on the whereabouts on the bank's assassin, and follow a suspect to New York City.
In New York, Salinger and Whitman are met by two New York Police Department detectives, Iggy Ornelas and Bernie Ward, who have a photograph of the assassin's face when he arrived in New York airport. Salinger, Ornelas, and Ward locate Dr. Isaacson to whose practice the assassin's leg brace has been traced. They find the assassin and follow him to the Solomon R. Guggenheim Museum.
Jonas Skarssen, the chairman of the IBBC, reveals to his senior men White and Wexler that the bank had Calvini killed so that they could deal with his sons to buy missile guidance systems in which the bank has invested. Since the bank knows that Salinger and Whitman are close to finding their assassin, they send a hit team to kill him at a meeting between him and his handler, Wexler. Wexler leaves and is arrested by Ornelas. As Salinger speaks to the assassin, a shootout at the Guggenheim erupts when a number of gunmen attempt to kill them with automatic weapons. They escape, but the assassin is mortally wounded. 
Question: What are the first names of the people who locate Dr. Isaacson?
[EX A]: Louis.

[EX Q]: Passage: Biographer Hannah Fink estimated that Oliver produced 290 works over a career of 22 years. Of these, public art works are Oliver's best known sculptures. These include Eyrie, created for Adelaide's Hyatt Hotel in 1993, and Magnolia and Palm, commissioned in 1999 by the Sydney Botanical Gardens, as part of the Sydney Sculpture Walk. That same year, Big Feathers was commissioned for the Queen Street Mall in Brisbane. It comprises two large feather-shaped forms suspended above the pedestrian precinct, representing "Queen Street's history of parades as well as the mall's connection between earth and sky".In 2000, Oliver's piece Entwine was a finalist in the inaugural Helen Lempriere National Sculpture Award, while in the following year, Oliver won the University of New South Wales inaugural sculpture commission competition, with her three-metre-high Globe. Other success followed, when Trace was selected for the National Gallery of Australia's 2002 National Sculpture Prize exhibition.In August 2002 she was one of five artists shortlisted by the Australian Government for a project to produce a public artwork celebrating the centenary of women's suffrage in Australia.By the 2000s most of Oliver's output constituted commissioned pieces, whether public or private. The most substantial of these is Vine, a 16.5 metre high sculpture installed as part of the $400 million refurbishment of the Sydney Hilton. Taking twelve months to create and requiring a budget of up to half million dollars, the work was completed in 2005. The sculpture was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders.By 2006, Oliver had held 18 solo exhibitions of her work, half of them at Roslyn Oxley9 Gallery, which represented her throughout her career as a sculptor. Only one of those solo exhibitions was held outside Australia: a 1992 exhibition at Auckland City Gallery. However, Oliver was represented in numerous international group shows, including five during the period 1983 to 1984, around the time she completed her master's degree in London. Four of the group shows at that time were in the United Kingdom; the fifth was at the Museum of Traditional Industries in Kyoto. Subsequent international group shows included 'Five Australian Artists' at Brest's Centre Culturale in 1988, the year she undertook an artist's residency in that city. Later group shows of which Oliver was part included 'Prospect '93' at the Frankfurter Kunstverein, 'Systems End: Contemporary Art in Australia', which exhibited in several east Asian galleries in 1996, and the Beijing International Biennale in 2003. 
Question: What is the name of the sculpture that was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders?
[EX A]: Vine.

[EX Q]: Passage: De Long's party found no immediate sign at their landing-place of any human habitation, and had only a sketchy idea of where they were—Petermann's map provided few useful details. On September 19, having buried their non-essential possessions in a mound marked by a tent pole, they set out in search of settlements. Progress was hampered by the poor physical condition of the men, in particular Eriksen, who was badly affected by frostbite. On September 21 they halted at two empty huts, probably part of a hunting camp, where Alexey raised spirits by shooting a deer to replenish their dwindling food stocks. De Long allowed his exhausted party several days' rest before resuming the march.On September 28 the party found a large hut, with signs of recent occupation–edible food in the store, and moccasin tracks in the snow. When searches in the locality brought no sign of people, De Long decided to move on. By October 4, Eriksen could not continue; the party halted at another abandoned hut where, on October 6, Eriksen died. On October 9, with the condition of several men worsening, De Long decided to send two of the fittest in the group, Nindemann and Noros, to seek help. Ambler was offered the opportunity to go with them, but felt that his duty as a doctor required him to stay with the main body.For the next week De Long's party struggled on, sometimes making barely a mile a day. Although they jettisoned more of their possessions on the way, De Long insisted on carrying his maps and journals. His entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine". A few days later Alexey, the group's principal hunter, shot a ptarmigan which provided soup. But Alexey was weakening, and on October 17 he died.On October 20, trapped by the weather and without supplies, the party came to a final halt. Throughout the march De Long had written up his journal each day, but after October 20 his entries became intermittent, largely limited to terse statements of the dying and the dead. He noted the deaths of Kaak and Lee on October 21, Iverson on the 28th, Dressler on the 29th. His last entry, dated October 30, records the deaths of Boyd and Görtz and ends "Mr Collins dying". 
Question: What is the last name of the person who entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine?"?
[EX A]:
De Long.
