Problem: Zhejiang:

Zhejiang was part of the Wu during the Three Kingdoms. Wu (229–280), commonly known as Eastern Wu or Sun Wu, had been the economically most developed state among the Three Kingdoms (220–280 CE). The historical novel Romance of the Three Kingdoms records that Zhejiang had the best-equipped, strong navy force. The story depicts how the states of Wei (魏) and Shu (蜀), lack of material resources, avoided direct confrontation with the Wu. In armed military conflicts with Wu, the two states relied intensively on tactics of camouflage and deception to steal Wu's military resources including arrows and bows.

 What was the least developed state among the Three Kingdoms?

A: unanswerable


Problem: Though Brazilians of at least partial African heritage make up a large percentage of the population, few blacks have been elected as politicians. The city of Salvador, Bahia, for instance, is 80% people of color, but voters have not elected a mayor of color. Journalists like to say that US cities with black majorities, such as Detroit and New Orleans, have not elected white mayors since after the civil rights movement, when the Voting Rights Act of 1965 protected the franchise for minorities, and blacks in the South regained the power to vote for the first time since the turn of the 20th century. New Orleans elected its first black mayor in the 1970s. New Orleans elected a white mayor after the widescale disruption and damage of Hurricane Katrina in 2005.
When did the US institute the Voting Rights Act?

Answer: 1965


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
All of Britain's campaigns against New France succeeded in 1759, part of what became known as an Annus Mirabilis. Fort Niagara and Fort Carillon on 8 July 1758 fell to sizable British forces, cutting off French frontier forts further west. On 13 September 1759, following a three-month siege of Quebec, General James Wolfe defeated the French on the Plains of Abraham outside the city. The French staged a counteroffensive in the spring of 1760, with initial success at the Battle of Sainte-Foy, but they were unable to retake Quebec, due to British naval superiority following the battle of Neuville. The French forces retreated to Montreal, where on 8 September they surrendered to overwhelming British numerical superiority.
When did General Wolfe take Quebec?
A: On 13 September 1759, following a three-month siege of Quebec, General James Wolfe defeated the French


Context and question: The term mainly refers to a mix of lithium and aluminosilicates that yields an array of materials with interesting thermomechanical properties. The most commercially important of these have the distinction of being impervious to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking. The negative thermal expansion coefficient (CTE) of the crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 °C.
How high of a temperature change can CTEs handle?
Answer: unanswerable


Question: After World War I, when Britain and France divided up the Middle East's countries, apart from Turkey, between them, pursuant to the Sykes-Picot agreement—in violation of solemn wartime promises of postwar Arab autonomy—there came an immediate reaction: the Muslim Brotherhood emerged in Egypt, the House of Saud took over the Hijaz, and regimes led by army officers came to power in Iran and Turkey. "[B]oth illiberal currents of the modern Middle East," writes de Bellaigne, "Islamism and militarism, received a major impetus from Western empire-builders." As often happens in countries undergoing social crisis, the aspirations of the Muslim world's translators and modernizers, such as Muhammad Abduh, largely had to yield to retrograde currents.
Is there an answer to this question: What did the aspirations of the Muslim world's translators find themselves yielding to?

Answer: retrograde currents


QUES: Socialism confronted consumerism in the chain State Department Stores (GUM), set up by Lenin in 1921 as a model retail enterprise. It operated stores throughout Russia and targeted consumers across class, gender, and ethnic lines. GUM was designed to advance the Bolsheviks' goals of eliminating private enterprise and rebuilding consumerism along socialist lines, as well as democratizing consumption for workers and peasants nationwide. GUM became a major propaganda purveyor, with advertising and promotional campaigns that taught Russians the goals of the regime and attempted to inculcate new attitudes and behavior. In trying to create a socialist consumer culture from scratch, GUM recast the functions and meanings of buying and selling, turning them into politically charged acts that could either contribute to or delay the march toward utopian communism. By the late 1920s, however, GUM's gandiose goals had proven unrealistic and largely alienated consumers, who instead learned a culture of complaint and entitlement. GUM's main function became one of distributing whatever the factories sent them, regardless of consumer demand or quality.

Who formed the State Department Stores, AKA GUM? 
What is the answer?
ANS:
Lenin
