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: Britain's declaration of war against Nazi Germany in September 1939 included the Crown colonies and India but did not automatically commit the Dominions of Australia, Canada, New Zealand, Newfoundland and South Africa. All soon declared war on Germany, but Ireland chose to remain legally neutral throughout the war.After the Fall of France in June 1940, Britain and the empire stood alone against Germany, until the German invasion of Greece on 7 April 1941. British Prime Minister Winston Churchill successfully lobbied President Franklin D. Roosevelt for military aid from the United States, but Roosevelt was not yet ready to ask Congress to commit the country to war. In August 1941, Churchill and Roosevelt met and signed the Atlantic Charter, which included the statement that "the rights of all peoples to choose the form of government under which they live" should be respected. This wording was ambiguous as to whether it referred to European countries invaded by Germany and Italy, or the peoples colonised by European nations, and would later be interpreted differently by the British, Americans, and nationalist movements.In December 1941, Japan launched, in quick succession, attacks on British Malaya, the United States naval base at Pearl Harbor, and Hong Kong. Churchill's reaction to the entry of the United States into the war was that Britain was now assured of victory and the future of the empire was safe, but the manner in which British forces were rapidly defeated in the Far East irreversibly harmed Britain's standing and prestige as an imperial power. Most damaging of all was the Fall of Singapore, which had previously been hailed as an impregnable fortress and the eastern equivalent of Gibraltar. The realisation that Britain could not defend its entire empire pushed Australia and New Zealand, which now appeared threatened by Japanese forces, into closer ties with the United States. This resulted in the 1951 ANZUS Pact between Australia, New Zealand and the United States of America. 
Question: What location was the city that was seen as impregnable fortress considered to be the eastern equivalent of?

Output: Gibraltar.


Input: Consider Input: Passage: Another letter to The New York Times blamed the shark infestation on the maneuvers of German U-boats near America's East Coast. The anonymous writer claimed, "These sharks may have devoured human bodies in the waters of the German war zone and followed liners to this coast, or even followed the Deutschland herself, expecting the usual toll of drowning men, women, and children." The writer concluded, "This would account for their boldness and their craving for human flesh."Decades later, there is no consensus among researchers over Murphy and Lucas's investigation and findings. Richard G. Fernicola published two studies of the event, and notes that "there are many theories behind the New Jersey attacks," and all are inconclusive. Researchers such as Thomas Helm, Harold W. McCormick, Thomas B. Allen, William Young, Jean Campbell Butler, and Michael Capuzzo generally agree with Murphy and Lucas. However, the National Geographic Society reported in 2002 that "some experts are suggesting that the great white may not in fact be responsible for many of the attacks pinned on the species. These people say the real culprit behind many of the reported incidents—including the famous 1916 shark attacks in New Jersey that may have served as inspiration for Jaws—may be the lesser known bull shark."Biologists George A. Llano and Richard Ellis suggest that a bull shark could have been responsible for the fatal Jersey Shore attacks. Bull sharks swim from the ocean into freshwater rivers and streams and have attacked people around the world. In his book Sharks: Attacks on Man (1975), Llano writes,
One of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea. Elsewhere in the book are accounts of well-documented shark-human interactions at Ahwaz, Iran, which is 90 miles (140 km) upriver from the sea. It may also be of interest to note that sharks live in Lake Nicaragua, a fresh-water body, and in 1944 there was a bounty offered for dead freshwater sharks, as they had "killed and severely injured lake bathers recently."
Ellis points out that the great white "is an oceanic species, and Schleisser's shark was caught in the ocean. To find it swimming in a tidal creek is, to say the least, unusual, and may even be impossible. The bull shark, however, is infamous for its freshwater meanderings, as well as for its pugnacious and aggressive nature."  He admits that "the bull shark is not a common species in New Jersey waters, but it does occur more frequently than the white."In an interview with Michael Capuzzo, ichthyologist George H. Burgess surmises, "The species involved has always been doubtful and likely will continue to generate spirited debate." Burgess, however, does not discount the great white:. 
Question: What is the full name of the book with accounts of well-documented shark-human interactions at Ahwaz, Iran?

Output: Sharks: Attacks on Man.


Input: Consider Input: Passage: Monteverdi was an established court composer in the service of Duke Vincenzo Gonzaga in Mantua when he wrote his first operas, L'Orfeo and L'Arianna, in the years 1606–08. After falling out with Vincenzo's successor, Duke Francesco Gonzaga, Monteverdi moved to Venice in 1613 and became director of music at St Mark's Basilica, a position he held for the rest of his life. Alongside his steady output of madrigals and church music, Monteverdi continued to compose works for the stage, though not actual operas. He wrote several ballets and, for the Venice carnival of 1624–25, Il combattimento di Tancredi e Clorinda ("The Battle of Tancred and Clorinda"), a hybrid work with some characteristics of ballet, opera and oratorio.
In 1637 fully-fledged opera came to Venice with the opening of the Teatro San Cassiano. Sponsored by the wealthy Tron family, this theatre was the first in the world specifically devoted to opera. The theatre's inaugural performance, on 6 March 1637, was L'Andromeda by Francesco Manelli and Benedetto Ferrari. This work was received with great enthusiasm, as was the same pair's La Maga fulminata the following year. In rapid succession three more opera houses opened in the city, as the ruling families of the Republic sought to express their wealth and status by investing in the new musical fashion. At first, Monteverdi remained aloof from these activities, perhaps on account of his age (he was over 70), or perhaps through the dignity of his office as maestro di capella at St. Mark's. Nevertheless, an unidentified contemporary, commenting on Monteverdi's silence, opined that the maestro might yet produce an opera for Venice: "God willing, one of these nights he too will step onto the stage." This remark proved prescient; Monteverdi's first public contribution to Venetian opera came in the 1639–40 carnival season, a revival of his L'Arianna at the Teatro San Moisè.L'Arianna was followed in rapid succession by three brand new Monteverdi operas, of which Il ritorno was the first. The second, Le nozze d' Enea in Lavinia ("The Marriage of Aeneas to Lavinia"), was performed during the 1640–41 carnival; Monteverdi's music is lost, but a copy of the libretto, of unknown authorship, survives. The last of the three, written for the 1642–43 carnival, was L'incoronazione di Poppea ("The Coronation of Poppea"), performed shortly before the composer's death in 1643. 
Question: What was the first opera that Monteverdi had wrote specifically for the Venice opera scene?


Output: Il ritorno.
