In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: In 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany. 
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance. 
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines. 
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.
[A]: What is the first name of the man that is fired for being German-born?


[Q]: Passage: On the night of 6 November 1995, a fire broke out in the Rova compound, destroying or severely damaging all of its buildings. Once the flames had been extinguished, all that remained of the original structures were the stone shells of the royal chapel and Manjakamiadana. Fire-fighters arrived late at the scene. Their capacity to douse the fire was hampered by the discovery that their fire hoses did not properly fit onto the nearby hydrants. In addition, the water pressure at the hydrants was significantly reduced due to Analamanga hilltop's high elevation. As the fire-fighters battled the flames, numerous bystanders ran into Rova compound buildings to retrieve artefacts of historic and cultural significance. Approximately 1,675 objects were saved out of an estimated total of 6,700. Some pillaging is believed to have occurred. On the night of the fire, the body of one of the queens was found in the public square in the centre of the city. A funeral vigil was held the following day for these royal remains. The remains were later identified as belonging to Ranavalona III, and have since been re-interred in the royal tombs at Ambohimanga.The destruction of the Rova of Antananarivo occurred at a time when the complex was in the final stages of the process to become classified as Madagascar's first cultural UNESCO World Heritage Site. Six people were initially charged in connection with the Rova's destruction in an Antananarivo court of law, but the official investigation concluded that the fire was an accident. Public accusations of a cover-up placed the blame for the fire on government officials, various ethnic groups, foreign powers and other parties. Widespread belief persists within and outside Madagascar that a deliberate arson was the cause. Rumoured motivations for arson at the Rova were numerous and remain unproven. The revelation that important financial archives had been destroyed early on the morning of the fire sparked rumours that corrupt government officials had lit the blaze to create a public distraction from their illicit activities. Other explanations have included popular dissatisfaction with the election of divisive mayor Guy Willy Razanamasy or a flare-up of long-standing tensions among coastal peoples resentful of Merina socio-political domination. Accusations were also made against both then-president Albert Zafy and his predecessor, Didier Ratsiraka. The debate over why and how the Rova burned remains an unresolved and highly contentious subject decades later.
[A]: How many cultural and historical objects were involved in the fire at the Rova compound?


[Q]: Passage: Possibly because of its size, The Sirens and Ulysses failed to sell at the 1837 Summer Exhibition. In October 1837 wealthy Manchester cotton merchant Daniel Grant, an admirer of Etty who had already commissioned Venus and her Doves from him, met Etty at Heaton Park races and offered to buy The Sirens and Ulysses and Etty's smaller Samson Betrayed by Delilah unseen for a total of £200. Etty was hoping for £400 for the two paintings, but on being told by Grant that his firm had lost £100,000 that year offered a price of £300 for the pair. Grant counter-offered £250 (about £22,000 in today's terms), which Etty refused. On leaving at the end of the evening, Grant suddenly said, "Will you take the money?", startling Etty, who in his surprise agreed. Grant died shortly afterwards, leaving the painting to his brother William, who in turn gave it to the Royal Manchester Institution in 1839.Etty considered the painting to be his best work, insisting that it form the centrepiece of his 1849 Royal Society of Arts solo exhibition. The Royal Manchester Institution was concerned that the painting would be damaged if moved, refusing to allow it to be used in the exhibition until Etty, and a number of influential friends, visited Manchester to beg them to release it. Etty died later that year, and his work enjoyed a brief boom in popularity. Interest in him declined over time, and by the end of the 19th century the cost of all his paintings had fallen below their original prices. As it was rarely exhibited, The Sirens and Ulysses had little influence on later artists, although it is credited as an influence on Frederic Leighton's 1858 The Fisherman and the Syren.
Ulysses and the Sirens is one of those great efforts of my Art achieved in the vigour of my life, I can never make again.
[A]:
What were the names of what Etty was hoping to get £400 for?
