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: Richard "Dick" Purcell, a taxi driver, aspires to achieve his dream of becoming a singer. After a couple of theatre critics discover him while riding in his cab, one of them recommends him to a radio producer. The producer's secretary, Alice Hughes, hears him sing and falls in love with him. She sets up an audition for Dick to sing for the sponsor, Mrs. Flaggenheim. He's late for his audition and blows his big chance. 
Convinced she must go to Italy to find a good enough singer, with enough "romance" to represent her fine cheese products, Mrs. Flaggenheim takes Alice with her to find one in Venice. Dick watches as Alice boards the ship and manages to get on board and work for his passage to Italy. When in Venice, he looks up his friend and mentor from New York City, professor de Vinci, who had gone ahead to use his old connections to help Dick's singing career. They manage to score a couple of jobs as gondoliers for an upcoming event.
Dick uses the opportunity to showcase his voice. Mrs. Flaggenheim hears him and wants to sign him to a contract immediately, thinking he's an authentic Italian named "Ricardo Purcelli". Alice recognizes him, but they continue to hide his true identity and they all go back to New York, where he quickly becomes a radio sensation. Alice's jilted boyfriend finds out Ricardo Purcelli is actually just Dick and gives him an ultimatum. Dick must decide if he wants to continue masquerading as Ricardo and finally attain the fame and fortune he'd always dreamed of....or give it all up for Alice, the one he loves. 
Question: In order to be with the radio producer's secretary, who must he stop pretending to be?
Example Output: Ricardo Purcelli.

Example Input: Passage: After graduation, Shostakovich initially embarked on a dual career as concert pianist and composer, but his dry style of playing was often unappreciated (his American biographer, Laurel Fay, comments on his "emotional restraint" and "riveting rhythmic drive"). He nevertheless won an "honorable mention" at the First International Chopin Piano Competition in Warsaw in 1927. He attributed the disappointment at the competition to suffering from appendicitis and the jury being all-Polish. He had his appendix removed in April 1927. After the competition Shostakovich met the conductor Bruno Walter, who was so impressed by the composer's First Symphony that he conducted it at its Berlin premiere later that year. Leopold Stokowski was equally impressed and gave the work its U.S. premiere the following year in Philadelphia and also made the work's first recording.
Shostakovich concentrated on composition thereafter and soon limited his performances primarily to those of his own works. In 1927 he wrote his Second Symphony (subtitled To October), a patriotic piece with a great pro-Soviet choral finale. Owing to its experimental nature, as with the subsequent Third Symphony, it was not critically acclaimed with the enthusiasm given to the First.
1927 also marked the beginning of Shostakovich's relationship with Ivan Sollertinsky, who remained his closest friend until the latter's death in 1944. Sollertinsky introduced the composer to the music of Mahler, which had a strong influence on his music from the Fourth Symphony onwards.
While writing the Second Symphony, Shostakovich also began work on his satirical opera The Nose, based on the story by Nikolai Gogol. In June 1929, against the composer's own wishes, the opera was given a concert performance; it was ferociously attacked by the Russian Association of Proletarian Musicians (RAPM). Its stage premiere on 18 January 1930 opened to generally poor reviews and widespread incomprehension among musicians.In the late 1920s and early 1930s, Shostakovich worked at TRAM, a proletarian youth theatre. Although he did little work in this post, it shielded him from ideological attack. Much of this period was spent writing his opera, Lady Macbeth of the Mtsensk District, which was first performed in 1934. It was immediately successful, on both popular and official levels. It was described as "the result of the general success of Socialist construction, of the correct policy of the Party", and as an opera that "could have been written only by a Soviet composer brought up in the best tradition of Soviet culture".Shostakovich married his first wife, Nina Varzar, in 1932. Initial difficulties led to a divorce in 1935, but the couple soon remarried when Nina became pregnant with their first child, Galina. 
Question: What is the name of the composer whose First Symphony was conducted by Bruno Walter at its Berlin premiere?
Example Output: Shostakovich.

Example Input: Passage: The first recorded inhabitants of the Susquehanna River valley were the Susquehannocks, an Iroquoian speaking people. Their name meant "people of the muddy river" in the Algonquian, but their name for themselves is unknown. Decimated by diseases and warfare, they had largely died out, moved away, or been assimilated into other tribes by the early 18th century. The lands of the West Branch Susquehanna River valley were then chiefly occupied by the Munsee phratry of the Lenape (or Delaware), and were under the nominal control of the Five (later Six) Nations of the Iroquois. Two important paths of these native indigenous peoples ran along parts of White Deer Hole Creek.The Great Island Path was a major trail that ran north along the Susquehanna River from the Saponi village of Shamokin at modern Sunbury, fording the river there and following the west bank of the West Branch Susquehanna River north until White Deer Hole valley. The path turned west at Allenwood and followed White Deer Hole Creek until about the present location of Elimsport. There it headed northwest, crossed North White Deer Ridge and passed west through the Nippenose valley, then turned north and crossed Bald Eagle Mountain via McElhattan Creek and ran along the south bank of the river to the Great Island (near the present day city of Lock Haven). The stretch from the mouth of the creek to the Nippenose valley is approximately followed by Route 44. From the Great Island, the Great Shamokin Path continued further west to the modern boroughs of Clearfield and Kittanning, the last on the Allegheny River.
Culbertson's Path followed White Deer Hole Creek west from Allenwood, then followed Spring Creek north, crossed Bald Eagle Mountain and followed Mosquito Run to the river at the current borough of Duboistown. Here it crossed the river to "French Margaret's Town" (western modern day Williamsport) before joining the major Sheshequin Path, which led north up Lycoming Creek to the North Branch of the Susquehanna River, modern New York, and the Iroquois there. These trails were only wide enough for one person, but settlers in White Deer Hole valley broadened the path to DuBoistown to take grain to Culbertson's mill on Mosquito Run, hence the name. Culbertson's Path was used as a part of the Underground Railroad until the American Civil War began in 1861. Escaped slaves would often wade in creeks to hide their scent from pursuing bloodhounds. In 2009, there is still a "Culbertson's Trail", for hiking over Bald Eagle Mountain from Pennsylvania Route 554 to Duboistown. 
Question: What crossed the river to French Margaret's Town?
Example Output:
Culbertson's Path.
