Problem: Queen (band):

The single "Killer Queen" from Sheer Heart Attack reached number two on the British charts, and became their first US hit, reaching number 12 on the Billboard Hot 100. It combines camp, vaudeville, and British music hall with May's guitar virtuosity. The album's second single, "Now I'm Here", a more traditional hard rock composition, was a number eleven hit in Britain, while the high speed rocker "Stone Cold Crazy" featuring May's uptempo riffs is a precursor to speed metal. In recent years, the album has received acclaim from music publications: In 2006, Classic Rock ranked it number 28 in "The 100 Greatest British Rock Albums Ever", and in 2007, Mojo ranked it No.88 in "The 100 Records That Changed the World". It is also the second of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.

Problem: Caesar was now the primary figure of the Roman state, enforcing and entrenching his powers. His enemies feared that he had ambitions to become an autocratic ruler. Arguing that the Roman Republic was in danger, a group of senators hatched a conspiracy and assassinated Caesar at a meeting of the Senate in March 44 BC. Mark Antony, Caesar's lieutenant, condemned Caesar's assassination, and war broke out between the two factions. Antony was denounced as a public enemy, and Caesar's adopted son and chosen heir, Gaius Octavianus, was entrusted with the command of the war against him. At the Battle of Mutina Mark Antony was defeated by the consuls Hirtius and Pansa, who were both killed.
Who was now considered to be the primary figure in the Roman state?

Answer: Caesar

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Insect respiration is accomplished without lungs. Instead, the insect respiratory system uses a system of internal tubes and sacs through which gases either diffuse or are actively pumped, delivering oxygen directly to tissues that need it via their trachea (element 8 in numbered diagram). Since oxygen is delivered directly, the circulatory system is not used to carry oxygen, and is therefore greatly reduced. The insect circulatory system has no veins or arteries, and instead consists of little more than a single, perforated dorsal tube which pulses peristaltically. Toward the thorax, the dorsal tube (element 14) divides into chambers and acts like the insect's heart. The opposite end of the dorsal tube is like the aorta of the insect circulating the hemolymph, arthropods' fluid analog of blood, inside the body cavity.:6165 Air is taken in through openings on the sides of the abdomen called spiracles.
Insect's respiratory system contains sacs, and what else?
A: internal tubes

Context and question: Increasing state control over the oil sector, the RCC began a program of nationalization, starting with the expropriation of British Petroleum's share of the British Petroleum-N.B. Hunt Sahir Field in December 1971. In September 1973, it was announced that all foreign oil producers active in Libya were to be nationalized. For Gaddafi, this was an important step towards socialism. It proved an economic success; while gross domestic product had been $3.8 billion in 1969, it had risen to $13.7 billion in 1974, and $24.5 billion in 1979. In turn, the Libyans' standard of life greatly improved over the first decade of Gaddafi's administration, and by 1979 the average per-capita income was at $8,170, up from $40 in 1951; this was above the average of many industrialized countries like Italy and the U.K.
In what month and year was a blanket nationalization of foreign oil production proclaimed?
Answer: September 1973

Question: Many people from Strasbourg were incorporated in the German Army against their will, and were sent to the eastern front, those young men and women were called Malgre-nous. Many tried to escape from the incorporation, join the French Resistance, or desert the Wehrmacht but many couldn't because they were running the risk of having their families sent to work or concentration camps by the Germans. Many of these men, especially those who did not answer the call immediately, were pressured to "volunteer" for service with the SS, often by direct threats on their families. This threat obliged the majority of them to remain in the German army. After the war, the few that survived were often accused of being traitors or collaborationists, because this tough situation was not known in the rest of France, and they had to face the incomprehension of many. In July 1944, 1500 malgre-nous were released from Soviet captivity and sent to Algiers, where they joined the Free French Forces. Nowadays history recognizes the suffering of those people, and museums, public discussions and memorials have been built to commemorate this terrible period of history of this part of Eastern France (Alsace and Moselle). Liberation of Strasbourg took place on 23 November 1944.
Is there an answer to this question: What were the men and women sent to the eastern front against their will called?

Answer: Malgre-nous
