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: Burges died, aged 53, in his Red Bed at the Tower House, at 11.45 p.m. on Wednesday 20 April 1881. While on a tour of works at Cardiff, he caught a chill and returned to London, half-paralysed, where he lay dying for some three weeks. Among his last visitors were Oscar Wilde and James Whistler. He was buried in the tomb he designed for his mother at West Norwood, London. On his death, John Starling Chapple, Burges's office manager and close associate for more than twenty years, wrote "a constant relationship ... with one of the brightest ornaments of the profession has rendered the parting most severe. Thank God his work will live and ... be the admiration of future students. I have hardly got to realize my lonely position yet. He was almost all the world to me." Lady Bute, wife of his greatest patron, wrote, "Dear Burges, ugly Burges, who designed such lovely things – what a duck."
In Saint Fin Barre's, together with memorials to his mother and sister, there is a memorial plaque to Burges, designed by him, and erected by his father. It shows the King of Heaven presiding over the four apostles, who hold open the Word of God. Under the inscription "Architect of this cathedral" is a simple shield and a small, worn, plaque with a mosaic surround, bearing Burges's entwined initials and name. Legal complications obstructed Burges's wish to be buried in the cathedral he had built. Burges's own words on Saint Fin Barre's, in his letter of January 1877 to the Bishop of Cork, sum up his career, "Fifty years hence, the whole affair will be on its trial and, the elements of time and cost being forgotten, the result only will be looked at. The great questions will then be, first, is this work beautiful and, secondly, have those to whom it was entrusted, done it with all their heart and all their ability.". 
Question: What was the last name of the person who was buried in a tomb designed for their mother?
Example Output: Burges.

Example Input: Passage: Wedge Donovan is a tough construction boss, building airstrips in the Pacific for the U.S. Navy during World War II. He clashes with his liaison officer, Lieutenant Commander Robert Yarrow, over the fact that his men are not allowed to arm themselves against the Japanese. When the enemy lands in force on the island, he finally takes matters into his own hands, leading his men into the fray. This prevents Yarrow from springing a carefully devised trap that would have wiped out the invaders in a murderous machinegun crossfire, with minimal American losses. Instead, many of Donovan's men are killed unnecessarily.
As a result of this tragedy, Yarrow finally convinces the US Navy to form Construction Battalions (CBs, or the more familiar "Seabees") with Donovan's assistance, despite their mutual romantic interest in war correspondent Constance Chesley. Donovan and many of his men enlist and receive formal military training.
The two men are teamed together on yet another island. The Japanese launch a major attack, which the Seabees barely manage to hold off, sometimes using heavy construction machinery such as bulldozers and a clamshell bucket. When word reaches Donovan of another approaching enemy column, there are no sailors left to oppose this new threat. In desperation, he rigs a bulldozer with explosives on its blade, intending to ram it into a petroleum storage tank. The plan works, sending a cascade of burning liquid into the path of the Japanese, who retreat in panic, right into the sights of waiting machine guns.  However, Wedge is shot in the process and dies in the explosion. 
Question: What is the last name of the man who clashes with Robert?
Example Output: Donovan.

Example Input: Passage: Tosca is an opera in three acts by Giacomo Puccini to an Italian libretto by Luigi Illica and Giuseppe Giacosa. It premiered at the Teatro Costanzi in Rome on 14 January 1900. The work, based on Victorien Sardou's 1887 French-language dramatic play, La Tosca, is a melodramatic piece set in Rome in June 1800, with the Kingdom of Naples's control of Rome threatened by Napoleon's invasion of Italy. It contains depictions of torture, murder and suicide, as well as some of Puccini's best-known lyrical arias.
Puccini saw Sardou's play when it was touring Italy in 1889 and, after some vacillation, obtained the rights to turn the work into an opera in 1895. Turning the wordy French play into a succinct Italian opera took four years, during which the composer repeatedly argued with his librettists and publisher. Tosca premiered at a time of unrest in Rome, and its first performance was delayed for a day for fear of disturbances. Despite indifferent reviews from the critics, the opera was an immediate success with the public.
Musically, Tosca is structured as a through-composed work, with arias, recitative, choruses and other elements musically woven into a seamless whole. Puccini used Wagnerian leitmotifs to identify characters, objects and ideas. While critics have often dismissed the opera as a facile melodrama with confusions of plot—musicologist Joseph Kerman called it a "shabby little shocker"—the power of its score and the inventiveness of its orchestration have been widely acknowledged. The dramatic force of Tosca and its characters continues to fascinate both performers and audiences, and the work remains one of the most frequently performed operas. Many recordings of the work have been issued, both of studio and live performances. 
Question: What is the first name of the person who used Wagnerian leitmotifs to identify characters, objects and ideas?
Example Output:
Giacomo.
