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.

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?
Gibraltar.

Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?
Ferrier.

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 full name of the man whose men are not allowed to arm themselves?

Wedge Donovan.
