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.

Input: Consider Input: Passage: After thief Alex Cardo gets caught and betrayed by his partner in crime John while stealing an ancient Jian in Thailand, he soon finds himself imprisoned and beaten. One of the guards, Demon, is particularly upset by Alex's appearance and tortures him whenever he gets the opportunity. Alex finds one friend and mentor in the jailhouse, Master Sun, who teaches him a superior fighting style called "Iron Hand". When a "best of the best kumite" is to take place, Demon gets an invitation. Now Master Sun and Alex need to find a way to let Alex take part in the kumite, too.
The final fight pits Alex and Demon together. At first, and for a long time, Demon has the upper hand in terms of strength and fighting ability. When Alex is down, he takes one last look at Master Sun and uses the "Iron Hand" against his opponent, severely damaging and defeating Demon. Alex is the winner, and as part of deals previously made, Master Sun is freed from prison, and so is Alex.
Question: What is the full name of the person who learns the "Iron Hand" fighting style?

Output: Alex Cardo.

Input: Consider Input: Passage: As the national media descended on Beach Haven, Spring Lake, and Matawan, the Jersey Shore attacks started a shark panic. According to Capuzzo, this panic was "unrivaled in American history," "sweeping along the coasts of New York and New Jersey and spreading by telephone and wireless, letter and postcard." At first, after the Beach Haven incident, scientists and the press reluctantly blamed the death of Charles Vansant on a shark. The New York Times reported that Vansant "was badly bitten in the surf ... by a fish, presumably a shark." Still, State Fish Commissioner of Pennsylvania and former director of the Philadelphia Aquarium James M. Meehan asserted in the Philadelphia Public Ledger that the shark was preying on the dog, but bit Vansant by mistake. He specifically de-emphasized the threat sharks posed to humans:
Despite the death of Charles Vansant and the report that two sharks having been caught in that vicinity recently, I do not believe there is any reason why people should hesitate to go in swimming at the beaches for fear of man-eaters. The information in regard to the sharks is indefinite and I hardly believe that Vansant was bitten by a man-eater. Vansant was in the surf playing with a dog and it may be that a small shark had drifted in at high water, and was marooned by the tide. Being unable to move quickly and without food, he had come in to bite the dog and snapped at the man in passing.
The media's response to the second attack was more sensational. Major American newspapers such as the Boston Herald, Chicago Sun-Times, The Philadelphia Inquirer, The Washington Post and San Francisco Chronicle placed the story on the front page. The New York Times' headline read, "Shark Kills Bather Off Jersey Beach". The growing panic had cost New Jersey resort owners an estimated $250,000 ($5,800,000 in 2018) in lost tourism, and sun bathing had declined by 75 percent in some areas. A press conference was convened on July 8, 1916, at the American Museum of Natural History with scientists Frederic Augustus Lucas, John Treadwell Nichols, and Robert Cushman Murphy as panelists. To calm the growing panic, the three men stressed that a third run in with a shark was unlikely, although they were admittedly surprised that sharks bit anyone at all. Nevertheless, Nicholsthe only ichthyologist in the triowarned swimmers to stay close to shore and to take advantage of the netted bathing areas installed at public beaches after the first attack.
Question: What are the full names of the three men who were admittedly surprised that sharks bit anyone at all?

Output: Frederic Augustus Lucas.

Input: Consider Input: Passage: Kathleen Mary Ferrier, CBE (22 April 1912 8 October 1953) was an English contralto singer who achieved an international reputation as a stage, concert and recording artist, with a repertoire extending from folksong and popular ballads to the classical works of Bach, Brahms, Mahler and Elgar. Her death from cancer, at the height of her fame, was a shock to the musical world and particularly to the general public, which was kept in ignorance of the nature of her illness until after her death.
The daughter of a Lancashire village schoolmaster, Ferrier showed early talent as a pianist, and won numerous amateur piano competitions while working as a telephonist with the General Post Office. She did not take up singing seriously until 1937, when after winning a prestigious singing competition at the Carlisle Festival she began to receive offers of professional engagements as a vocalist. Thereafter she took singing lessons, first with J.E. Hutchinson and later with Roy Henderson. After the outbreak of the Second World War Ferrier was recruited by the Council for the Encouragement of Music and the Arts (CEMA), and in the following years sang at concerts and recitals throughout the UK. In 1942 her career was boosted when she met the conductor Malcolm Sargent, who recommended her to the influential Ibbs and Tillett concert management agency. She became a regular performer at leading London and provincial venues, and made numerous BBC radio broadcasts.
In 1946, Ferrier made her stage debut, in the Glyndebourne Festival premiere of Benjamin Britten's opera The Rape of Lucretia. A year later she made her first appearance as Orfeo in Gluck's Orfeo ed Euridice, a work with which she became particularly associated. By her own choice, these were her only two operatic roles. As her reputation grew, Ferrier formed close working relationships with major musical figures, including Britten, Sir John Barbirolli, Bruno Walter and the accompanist Gerald Moore. She became known internationally through her three tours to the United States between 1948 and 1950 and her many visits to continental Europe.
Ferrier was diagnosed with breast cancer in March 1951. In between periods of hospitalisation and convalescence she continued to perform and record; her final public appearance was as Orfeo, at the Royal Opera House in February 1953, eight months before her death. Among her many memorials, the Kathleen Ferrier Cancer Research Fund was launched in May 1954. The Kathleen Ferrier Scholarship Fund, administered by the Royal Philharmonic Society, has since 1956 made annual awards to aspiring young professional singers.
Question: What is the last name of the person who took singing lessons with Roy Henderson?
Output: Ferrier.
