Problem: Another example relates to AIG, which insured obligations of various financial institutions through the usage of credit default swaps. The basic CDS transaction involved AIG receiving a premium in exchange for a promise to pay money to party A in the event party B defaulted. However, AIG did not have the financial strength to support its many CDS commitments as the crisis progressed and was taken over by the government in September 2008. U.S. taxpayers provided over $180 billion in government support to AIG during 2008 and early 2009, through which the money flowed to various counterparties to CDS transactions, including many large global financial institutions.
When did the government take over AIG?

Answer: September 2008

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Russell's ministry, though Whig, was not favoured by the Queen. She found particularly offensive the Foreign Secretary, Lord Palmerston, who often acted without consulting the Cabinet, the Prime Minister, or the Queen. Victoria complained to Russell that Palmerston sent official dispatches to foreign leaders without her knowledge, but Palmerston was retained in office and continued to act on his own initiative, despite her repeated remonstrances. It was only in 1851 that Palmerston was removed after he announced the British government's approval of President Louis-Napoleon Bonaparte's coup in France without consulting the Prime Minister. The following year, President Bonaparte was declared Emperor Napoleon III, by which time Russell's administration had been replaced by a short-lived minority government led by Lord Derby.
President Bonaparte was declared what in France?
A: Emperor Napoleon III

Context and question: Some of the most influential theorists on emotion from the 20th century have died in the last decade. They include Magda B. Arnold (19032002), an American psychologist who developed the appraisal theory of emotions; Richard Lazarus (19222002), an American psychologist who specialized in emotion and stress, especially in relation to cognition; Herbert A. Simon (19162001), who included emotions into decision making and artificial intelligence; Robert Plutchik (19282006), an American psychologist who developed a psychoevolutionary theory of emotion; Robert Zajonc (19232008) a PolishAmerican social psychologist who specialized in social and cognitive processes such as social facilitation; Robert C. Solomon (19422007), an American philosopher who contributed to the theories on the philosophy of emotions with books such as What Is An Emotion?: Classic and Contemporary Readings (Oxford, 2003); Peter Goldie (19462011), a British philosopher who specialized in ethics, aesthetics, emotion, mood and character; Nico Frijda (19272015), a Dutch psychologist who advanced the theory that human emotions serve to promote a tendency to undertake actions that are appropriate in the circumstances, detailed in his book The Emotions (1986).
What theory was developed by Arnold?
Answer: the appraisal theory of emotions

Question: Widespread segregation in 19th- and early 20th-century North America made it difficult for African-Americans to join Lodges outside of Prince Hall jurisdictions and impossible for inter-jurisdiction recognition between the parallel U.S. Masonic authorities. By the 1980s, such discrimination was a thing of the past, and today most U.S. Grand Lodges recognise their Prince Hall counterparts, and the authorities of both traditions are working towards full recognition. The United Grand Lodge of England has no problem with recognising Prince Hall Grand Lodges. While celebrating their heritage as lodges of black Americans, Prince Hall is open to all men regardless of race or religion.
Is there an answer to this question: When did North American Masonic lodges recognize members of the Prince Hall Lodge?

Answer: By the 1980s

Question: Modern morphology recognizes a continuum between the major morphological categories of root, stem (caulome), leaf (phyllome) and trichome. Furthermore, it emphasizes structural dynamics. Modern systematics aims to reflect and discover phylogenetic relationships between plants. Modern Molecular phylogenetics largely ignores morphological characters, relying on DNA sequences as data. Molecular analysis of DNA sequences from most families of flowering plants enabled the Angiosperm Phylogeny Group to publish in 1998 a phylogeny of flowering plants, answering many of the questions about relationships among angiosperm families and species. The theoretical possibility of a practical method for identification of plant species and commercial varieties by DNA barcoding is the subject of active current research.
Is there an answer to this question: What did the Angiosperm Phylogeny group use determine a phylogeny of flowering plants?

Answer:
Molecular analysis of DNA
