Problem: The 19th century also saw the use of red in art to create specific emotions, not just to imitate nature. It saw the systematic study of color theory, and particularly the study of how complementary colors such as red and green reinforced each other when they were placed next to each other. These studies were avidly followed by artists such as Vincent van Gogh. Describing his painting, The Night Cafe, to his brother Theo in 1888, Van Gogh wrote: "I sought to express with red and green the terrible human passions. The hall is blood red and pale yellow, with a green billiard table in the center, and four lamps of lemon yellow, with rays of orange and green. Everywhere it is a battle and antithesis of the most different reds and greens."
What was the name of vincent van Gogh's brother?

Answer: Theo


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Ibn Sina subsequently settled at Rey, in the vicinity of modern Tehran, the home town of Rhazes; where Majd Addaula, a son of the last Buwayhid emir, was nominal ruler under the regency of his mother (Seyyedeh Khatun). About thirty of Ibn Sina's shorter works are said to have been composed in Rey. Constant feuds which raged between the regent and her second son, Shams al-Daula, however, compelled the scholar to quit the place. After a brief sojourn at Qazvin he passed southwards to Hamadãn where Shams al-Daula, another Buwayhid emir, had established himself. At first, Ibn Sina entered into the service of a high-born lady; but the emir, hearing of his arrival, called him in as medical attendant, and sent him back with presents to his dwelling. Ibn Sina was even raised to the office of vizier. The emir decreed that he should be banished from the country. Ibn Sina, however, remained hidden for forty days in sheikh Ahmed Fadhel's house, until a fresh attack of illness induced the emir to restore him to his post. Even during this perturbed time, Ibn Sina persevered with his studies and teaching. Every evening, extracts from his great works, the Canon and the Sanatio, were dictated and explained to his pupils. On the death of the emir, Ibn Sina ceased to be vizier and hid himself in the house of an apothecary, where, with intense assiduity, he continued the composition of his works.
Who did Ibn Sina hide for forty days?
A: unanswerable


Context and question: From the 1930s through much of the 1960s, Florida was essentially a one-party state dominated by white conservative Democrats, who together with other Democrats of the Solid South, exercised considerable control in Congress. They gained federal money from national programs; like other southern states, Florida residents have received more federal monies than they pay in taxes: the state is a net beneficiary. Since the 1970s, the conservative white majority of voters in the state has largely shifted from the Democratic to the Republican Party. It has continued to support Republican presidential candidates through the 20th century, except in 1976 and 1996, when the Democratic nominee was from the South. They have had "the luxury of voting for presidential candidates who pledge to cut taxes and halt the expansion of government while knowing that their congressional delegations will continue to protect federal spending."
What party dominated Florida before 1930?
Answer: unanswerable


Question: Economists argue that one of the factors behind the differing economic development in Africa and Asia is that in Africa, corruption has primarily taken the form of rent extraction with the resulting financial capital moved overseas rather than invested at home (hence the stereotypical, but often accurate, image of African dictators having Swiss bank accounts). In Nigeria, for example, more than $400 billion was stolen from the treasury by Nigeria's leaders between 1960 and 1999.
Is there an answer to this question: In Africa, the finances are often moved where?

Answer: overseas
