Ex Input:
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 Output:
Louis.

Passage: Three species of mangrove trees exist in the region: red (Rhizophora mangle), black (Avicennia germinans), and white (Laguncularia racemosa), although all are from different families. All have the same characteristics: they are tolerant of salt, brackish, and fresh water; they grow in oxygen-poor soil; and they can survive drastic water-level changes. Black and white mangroves excrete salt from under their leaves, and red mangroves filter the salinity of sea water. All species are integral to coastline protection during severe storms. Red mangroves, for example, have far-reaching roots that trap sediments. The trees not only stabilize coastlines, but add land as more sand and decaying vegetation is trapped in the root systems. All three mangroves also absorb the energy of waves and storm surges.
The estuaries act as fisheries for fry and nurseries for crustaceans. Shrimp, oysters, crabs, whelks, cockles, and snails thrive in these waters, as do primordial horseshoe crabs (Limulus polyphemus). The region supports a $59 million-a-year Tortugas pink shrimp (Farfantepenaeus duorarum) industry, and a $22 million-a-year stone crab (Menippe mercenaria) industry.  Between 80 and 90 percent of species that are harvested commercially in Florida are born or spend time in the shallow waters near the Everglades. Oysters and mangroves work in tandem to build up the coastline. The sand around the coastline has minute white particles of quartz and fine shells. When currents are right, oysters grow in colonies or beds, and deposit their shells, reinforcing the bed. Mangrove seeds, called propagules, are full embryos and float in water until they reach a favorable location and take root, often on oyster beds. They shed skin and litter, ensuring other trees will not compete for space and nutrients.Mangroves also serve as excellent rookeries for birds. Wading birds, such as roseate spoonbills (Platalea ajaja), egrets, and tricolored herons (Egretta tricolor) use the mangroves as a nursery, due to the proximity of food sources and the protection offered from most prey. Thousands of birds can nest in the mangroves at once, making a noisy and messy colony, but their droppings fertilize the mangrove trees. Shorebirds like rails, terns and gulls; diving birds such as pelicans and grebes; and birds of prey such as ospreys, hawks and vultures are among the more than 100 species of birds that use Everglades mangrove trees to raise their young. 
Question: What are the full scientific names of the three species of mangrove trees that exist in the Everglades?

Ex Output:
Rhizophora mangle.

Passage: Lyon Gaultier is a paratrooper in the French Foreign Legion, stationed in Djibouti, North Africa. His brother, who is married to an American woman in Los Angeles, is burned alive during a drug deal gone wrong and suffers third-degree burns, dying shortly afterward. Lyon deserts his legion when he finds out they have been withholding letters from his brother's wife and ultimately refuse to let him see his dying brother. He steals a jeep and escapes through the desert, finding work on a tramp steamer headed for the U.S. Meanwhile, the Legion Commandant travels to Paris, arriving at the government Consulate, where he is told that Lyon's desertion is ranked at low importance with the LAPD, so the Commandant suggests sending two of his own men to bring Gaultier back, which is approved.
Lyon arrives pennyless in New York City and is attracted to an illegal street fighting match that is being run by a New Yorker called Joshua, a man who runs fights for money. Gaultier steps forward to take part in the next fight and destroys his opponent, leaving Joshua looking astounded at what he just saw. Joshua takes Lyon to meet a person called Cynthia, also known as 'The Lady' who organizes underground fights for the rich elite and she decides to sponsor him. Figuring that this would be the best way to earn the money he needs to get to L.A., Lyon fights in a no-holds-barred bare-knuckle fights to finance the trip.
Once in L.A. Lyon goes to the hospital where his brother was taken. He learns that he cannot avenge his brother's murder, as he failed to identify his killers before dying. Grief-stricken, Lyon asks the help of Joshua who tracks down his brother's widow's address. However she refuses to accept any financial aid from him, even though she obviously needs it, because she is angry with Lyon for "deserting" his brother years ago. She threatens to call the cops and Lyon has no choice but to leave. 
Question: What is the full name of the person whose brother failed to identify his killers before dying?

Ex Output:

Lyon Gaultier.
