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: There are over 40 species of mammals in the Pine Creek Gorge. Leonard Harrison State Park's extensive forest cover makes it a habitat for "big woods" wildlife, including white-tailed deer, black bear, wild turkey, red and gray squirrels. Less common creatures include bobcats, coyote, fishers, river otters, and timber rattlesnakes. There are over 26 species of fish in Pine Creek, including trout, suckers, fallfish, and rock bass. Other aquatic species include crayfish and frogs.Several species have been reintroduced to the gorge. White-tailed deer were imported from Michigan and released throughout Pennsylvania to reestablish what had once been a thriving population. The current population of deer in Pennsylvania are descended from the original stock introduced beginning in 1906, after the lumberman had moved out of the area. The deer population has grown so much that today they exceed their carrying capacity in many areas. River otters were successfully reintroduced in 1983 and now breed in the gorge. Despite the fears of anglers, their diet is only 5 percent trout.Fishers, medium-sized weasels, were reintroduced to Pine Creek Gorge as part of an effort to establish a healthy population of fishers in Pennsylvania. Prior to the lumber era, fishers were numerous throughout the forests of Pennsylvania. They are generalized predators and will hunt any smaller creatures in their territory, including porcupines. Elk have been reintroduced west of the gorge in Clinton County and occasionally wander near the west rim of the canyon. Coyotes have come back on their own. Invasive insect species in the gorge include gypsy moths, which eat all the leaves off trees, especially oaks, and hemlock woolly adelgids, which weaken and kill hemlocks. Invasive plant species include purple loosestrife and Japanese knotweed. 
Question: What is the full name of the place that has gypsy moths?
Example Output: Pine Creek Gorge.

Example Input: Passage: Massenet was a prolific composer; he put this down to his way of working, rising early and composing from four o'clock in the morning until midday, a practice he maintained all his life. In general he worked fluently, seldom revising, although Le roi de Lahore, his nearest approach to a traditional grand opera, took him several years to complete to his own satisfaction. It was finished in 1877 and was one of the first new works to be staged at the Palais Garnier, opened two years previously. The opera, with a story taken from the Mahabharata, was an immense success and was quickly taken up by the opera houses of eight Italian cities. It was also performed at the Hungarian State Opera House, the Bavarian State Opera, the Semperoper, Dresden, the Teatro Real in Madrid, and the Royal Opera House, Covent Garden, in London. After the first Covent Garden performance, The Times summed the piece up in a way that was frequently to be applied to the composer's operas: "M. Massenet's opera, although not a work of genius proper, is one of more than common merit, and contains all the elements of at least temporary success."This period was an early high point in Massenet's career. He had been made a chevalier of the Legion of Honour in 1876, and in 1878 he was appointed professor of counterpoint, fugue and composition at the Conservatoire under Thomas, who was now the director. In the same year he was elected to the Institut de France, a prestigious honour, rare for a man in his thirties. Camille Saint-Saëns, whom Massenet beat in the election for the vacancy, was resentful at being passed over for a younger composer. When the result of the election was announced, Massenet sent Saint-Saëns a courteous telegram: "My dear colleague: the Institut has just committed a great injustice". Saint-Saëns cabled back, "I quite agree." He was elected three years later, but his relations with Massenet remained cool.Massenet was a popular and respected teacher at the Conservatoire. His pupils included Bruneau, Charpentier, Chausson, Hahn, Leroux, Pierné, Rabaud and Vidal. He was known for the care he took in drawing out his pupils' ideas, never trying to impose his own. One of his last students, Charles Koechlin, recalled Massenet as a voluble professor, dispensing "a teaching active, living, vibrant, and moreover comprehensive". According to some writers, Massenet's influence extended beyond his own students. In the view of the critic Rodney Milnes, "In word-setting alone, all French musicians profited from the freedom he won from earlier restrictions." Romain Rolland and Francis Poulenc have both considered Massenet an influence on Debussy's Pelléas et Mélisande; Debussy was a student at the Conservatoire during Massenet's professorship but did not study under him. 
Question: What was the full name of one of Massenet's last students?
Example Output: Charles Koechlin.

Example Input: Passage: Mrs Baring, a businesswoman and patron of classical music, has arranged for a celebrated Eastern Bloc musician, Spolenski, to play in a series of concerts in Britain.

Johnny Burns, an aspiring singer is hanging around a music shop he frequents when he spot Mrs Baring's daughter, Joanna.

Later, when Mrs Baring is short of a butler he offers his services and is so successful at his duties that he is taken on in a more permanent basis. He slowly begins to bond and court Joanna while doing his best to conceal his love of popular, modern music from Mrs Baring who is resolutely opposed to it and has forbidden her daughter to listen to it. Her financial problems continue to mount up and her phone is cut due to unpaid bills.
Burns' friend and agent, Freddy, meanwhile has secured him an audition with Greenslade, a major popular record label, who are impressed with his performance. Convinced he is going to be a major star, they make plans to sign him up on a long-term contract. Burn's first demand of Greenslade is for money to pay for Mrs Baring's telephone to be restored. Mrs Baring is relieved by this gesture, but  believes the money came from one of her other friends rather than Burns. 
Question: Who is the butler's friend?

Freddy.
