Problem: Frédéric Chopin:

Chopin's public popularity as a virtuoso began to wane, as did the number of his pupils, and this, together with the political strife and instability of the time, caused him to struggle financially. In February 1848, with the cellist Auguste Franchomme, he gave his last Paris concert, which included three movements of the Cello Sonata Op. 65.

When did Chopin last perform?

A: February 1848


Problem: Since annelids are soft-bodied, their fossils are rare – mostly jaws and the mineralized tubes that some of the species secreted. Although some late Ediacaran fossils may represent annelids, the oldest known fossil that is identified with confidence comes from about 518 million years ago in the early Cambrian period. Fossils of most modern mobile polychaete groups appeared by the end of the Carboniferous, about 299 million years ago. Palaeontologists disagree about whether some body fossils from the mid Ordovician, about 472 to 461 million years ago, are the remains of oligochaetes, and the earliest indisputable fossils of the group appear in the Tertiary period, which began 65 million years ago.
What types of annelids disappeared 299 million years ago?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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? 
A: Lenin


Context and question: Sony's PlayStation 3 has extensive HD compatibility because of its built in Blu-ray disc based player, so does Microsoft's Xbox 360 with the addition of Netflix and Windows Media Center HTPC streaming capabilities, and the Zune marketplace where users can rent or purchase digital HD content. Recently, Nintendo released a next generation high definition gaming platform, The Wii U, which includes TV remote control features in addition to IPTV streaming features like Netflix. The HD capabilities of the consoles has influenced some developers to port games from past consoles onto the PS3, Xbox 360 and Wii U, often with remastered or upscaled graphics.
What high definition gaming platform did Nintendo recently release?
Answer: The Wii U


Question: Following the end of World War II the educational gap between White and Black Americans was widened by Dwight D. Eisenhower's GI Bill. This piece of legislation paved the way for white GIs to attend college. Despite their veteran status returning black servicemen were not afforded loans at the same rate as whites. Furthermore, at the time of its introduction, segregation was still the law of the land barring blacks from the best institutions. Overall, "Nearly 8 million servicemen and servicewomen were educated under the provisions of the GI Bill after World War II. But for blacks, higher educational opportunities were so few that the promise of the GI Bill went largely unfulfilled."
Is there an answer to this question: What major event preceded the growth of the divide in education between White and Asian Americans?

Answer: unanswerable


Question: Like Finnish and Hungarian, Estonian is a somewhat agglutinative language, but unlike them, it has lost vowel harmony, the front vowels occurring exclusively on the first or stressed syllable, although in older texts the vowel harmony can still be recognized. Furthermore, the apocope of word-final sounds is extensive and has contributed to a shift from a purely agglutinative to a fusional language.[citation needed] The basic word order is subject–verb–object.
Is there an answer to this question: What kind of harmony has Estonian lost?

Answer:
vowel
