In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: Dr. Frank Peralta is stabbed to death in his apartment one night. The detective on the case, Lt. Stevenson, quickly finds multiple witnesses putting Peralta's lover, Terry Collins, at the scene. However, when Stevenson finds Terry and questions her, she has an iron-clad alibi with multiple witnesses. It is revealed that Terry has an identical twin sister, Ruth, and the pair share the same job and routinely switch places for their own benefit. Stevenson and the district attorney are unable to prosecute, since the twins refuse to confirm which one of them has the alibi.
Unable to accept the "perfect crime", Lt. Stevenson asks Dr. Scott Elliot for help. Scott is an expert on twin study, and has been routinely encountering the Collins twins at their shared place of work, but does not know which one is which. As a front, Scott asks Terry and Ruth if he can study both of them individually as part of his research. The twins accept, though Ruth is worried that Scott might find out that Terry was at Peralta's apartment the night of the murder. However, Terry is attracted to Scott and insists that they can keep the secret for the sake of seeing him. She also comforts Ruth, reminding her that she was only at Peralta's apartment but didn't kill him.
From Scott's psychological tests and by spending time with them, he discovers that Ruth is kind and loving, while Terry is highly intelligent, insane, and has been manipulating Ruth almost their entire lives. Terry is jealous that people keep preferring Ruth over her, and is again enraged when Scott falls in love with Ruth instead of her. Terry starts methodically gaslighting Ruth, making her believe that she's hallucinating and going insane, in the hopes of pushing her to suicide. 
Question: What is the last name of the person whose murder the insane woman is suspected of committing?
Example Output: Peralta.

Example Input: Passage: Conquistadors often wore steel armour that included chainmail and helmets. The Spanish were sufficiently impressed by the quilted cotton armour of their Maya enemies that they adopted it in preference to their own steel armour. Maya weaponry was not sufficiently powerful to justify the discomfort of wearing European armour. Quilted cotton armour, although still uncomfortably hot, was flexible and weighed much less. The Maya armour was adapted by the Spanish, who used knee-length quilted cotton tunics and Spanish-style caps. Horsemen wore long quilted cotton leg protectors; their horses were also protected with padded cotton armour. After the final push to the Petén lakes in early 1697, the Spanish recorded that they left with their garrison over 50 Dutch- and French-made muskets, three 1-pound (0.45 kg) calibre light cannons (piezas) cast from iron and mounted on carriages, four iron and two bronze pedreros (2-chambered stone-launchers) and six of at least eight bronze light cannons (known as esmiriles). 
Question: Who had four iron and two bronze pedreros?
Example Output: the Spanish.

Example Input: Passage: It has been eighteen months since Kurt Sloane killed Tong Po and avenged the death of his brother Eric. Now a professional mixed martial artist, Kurt defeats Renato Sobral using a move he calls the "Hurricane Armbar", a hurricanrana into an armbar. Kurt has been plagued by nightmares where he and his wife Liu are on a train and he finds himself fighting on the train which ends with him falling into water and possibly drowning. After the fight, Kurt is met by two U.S. Marshals who inform him that he must return to Thailand to be implicated in the death of Tong Po. When Kurt asks to see one of the Marshal's badges, he is tasered. 
Awakening in a prison in Thailand, Kurt meets Thomas Tang Moore, the mastermind behind the underground tournament where Kurt, Eric, and Tong Po have competed. Moore tells Kurt that when Tong Po was defeated, he was to remain there as the new champion, but instead with Kurt returning home, Moore needed to find a new champion. Moore offers Kurt to fight the new champion, Mongkut, a 6'8" 400-lb. fighter. Kurt finds himself taunted by Crawford, Tong Po's former right hand man who is working for Moore. Moore offers Kurt $1 million to fight Mongkut, but Kurt refuses. Stuck in prison, Kurt finds himself under constant threat from various prisoners, in which he then finds himself whipped by the prison guards each night. During one encounter, Kurt runs into Briggs, an American boxer who soon bonds with Kurt and even offers him a way to go through the pain from the whippings. Kurt also soon learns that his Muay Thai teacher, Durand, is now training some of the prisoners, but reveals that for his troubles, he has been blinded. 
Question: What are the first names of the two people riding on the train?
Example Output:
Kurt.
