Problem: Miami:

Black labor played a crucial role in Miami's early development. During the beginning of the 20th century, migrants from the Bahamas and African-Americans constituted 40 percent of the city's population. Whatever their role in the city's growth, their community's growth was limited to a small space. When landlords began to rent homes to African-Americans in neighborhoods close to Avenue J (what would later become NW Fifth Avenue), a gang of white man with torches visited the renting families and warned them to move or be bombed.

What was NW Fourth Avenue previously called?

Problem: China, France, Russia, the United Kingdom and the United States are often referred to as great powers by academics due to "their political and economic dominance of the global arena". These five nations are the only states to have permanent seats with veto power on the UN Security Council. They are also the only recognized "Nuclear Weapons States" under the Nuclear Non-Proliferation Treaty, and maintain military expenditures which are among the largest in the world. However, there is no unanimous agreement among authorities as to the current status of these powers or what precisely defines a great power. For example, sources have at times referred to China, France, Russia and the United Kingdom as middle powers.
What treaty addresses global political and economic dominance?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In Iran (Persia), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran. In Persian poets' poems, especially Ferdowsi's Shahname, there are references to cotton ("panbe" in Persian). Marco Polo (13th century) refers to the major products of Persia, including cotton. John Chardin, a French traveler of the 17th century who visited the Safavid Persia, spoke approvingly of the vast cotton farms of Persia.
What Frenchman in the 13th century noted cotton farming in Persia?
A: unanswerable


Context and question: Luftwaffe policy at this point was primarily to continue progressive attacks on London, chiefly by night attack; second, to interfere with production in the vast industrial arms factories of the West Midlands, again chiefly by night attack; and third to disrupt plants and factories during the day by means of fighter-bombers. Kesselring, commanding Luftflotte 2, was ordered to send 50 sorties per night against London and attack eastern harbours in daylight. Sperrle, commanding Luftflotte 3, was ordered to dispatch 250 sorties per night including 100 against the West Midlands. Seeschlange would be carried out by Fliegerkorps X (10th Air Corps) which concentrated on mining operations against shipping. It also took part in the bombing over Britain. By 19/20 April 1941, it had dropped 3,984 mines, ⅓ of the total dropped. The mines' ability to destroy entire streets earned them respect in Britain, but several fell unexploded into British hands allowing counter-measures to be developed which damaged the German anti-shipping campaign.
What did the Fliegerkorps X concentrate on?
Answer: mining operations against shipping


Question: "Junior" Laemmle persuaded his father to bring Universal up to date. He bought and built theaters, converted the studio to sound production, and made several forays into high-quality production. His early efforts included the critically mauled part-talkie version of Edna Ferber's novel Show Boat (1929), the lavish musical Broadway (1929) which included Technicolor sequences; and the first all-color musical feature (for Universal), King of Jazz (1930). The more serious All Quiet on the Western Front (1930), won its year's Best Picture Oscar.
Is there an answer to this question: What 1929 all-color musical feature did Universal produce?

Answer: unanswerable


The son of Murad II, Mehmed the Conqueror, reorganized the state and the military, and conquered Constantinople on 29 May 1453. Mehmed allowed the Orthodox Church to maintain its autonomy and land in exchange for accepting Ottoman authority. Because of bad relations between the states of western Europe and the later Byzantine Empire, the majority of the Orthodox population accepted Ottoman rule as preferable to Venetian rule. Albanian resistance was a major obstacle to Ottoman expansion on the Italian peninsula.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was the son of Murad II?
Ah, so..
Mehmed the Conqueror
