Problem: Napoleon:

Before going to Iberia, Napoleon decided to address several lingering issues with the Russians. At the Congress of Erfurt in October 1808, Napoleon hoped to keep Russia on his side during the upcoming struggle in Spain and during any potential conflict against Austria. The two sides reached an agreement, the Erfurt Convention, that called upon Britain to cease its war against France, that recognized the Russian conquest of Finland from Sweden, and that affirmed Russian support for France in a possible war against Austria "to the best of its ability." Napoleon then returned to France and prepared for war. The Grande Armee, under the Emperor's personal command, rapidly crossed the Ebro River in November 1808 and inflicted a series of crushing defeats against the Spanish forces. After clearing the last Spanish force guarding the capital at Somosierra, Napoleon entered Madrid on 4 December with 80,000 troops. He then unleashed his soldiers against Moore and the British forces. The British were swiftly driven to the coast, and they withdrew from Spain entirely after a last stand at the Battle of Corunna in January 1809.

The Erfurt Convention insisted that Britain stop war against which nation?

A: France

Problem: By 1990, the Census Bureau included more than a dozen ethnic/racial categories on the census, reflecting not only changing social ideas about ethnicity, but the wide variety of immigrants who had come to reside in the United States due to changing historical forces and new immigration laws in the 1960s. With a changing society, more citizens have begun to press for acknowledging multiracial ancestry. The Census Bureau changed its data collection by allowing people to self-identify as more than one ethnicity. Some ethnic groups are concerned about the potential political and economic effects, as federal assistance to historically underserved groups has depended on Census data. According to the Census Bureau, as of 2002, over 75% of all African Americans had multiracial ancestries.
By 2002, what percent of African Americans had multiracial ancestries?
---
Answer: over 75%

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A combined UN civilian and peace-keeping force called UNTAG (United Nations Transition Assistance Group) under Finnish diplomat Martti Ahtisaari was deployed from April 1989 to March 1990 to monitor the peace process, elections and supervise military withdrawals. As UNTAG began to deploy peacekeepers, military observers, police, and political workers, hostilities were briefly renewed on the day the transition process was supposed to begin. After a new round of negotiations, a second date was set and the elections process began in earnest. After the return of SWAPO exiles (over 46,000 exiles), Namibia's first one-person one-vote elections for the constitutional assembly took place in November 1989. The official election slogan was "Free and Fair Elections". This was won by SWAPO although it did not gain the two-thirds majority it had hoped for; the South African-backed Democratic Turnhalle Alliance (DTA) became the official opposition. The elections were peaceful and declared free and fair.
Who backed SWAPO?
A: unanswerable

Context and question: John had already begun to improve his Channel forces before the loss of Normandy and he rapidly built up further maritime capabilities after its collapse. Most of these ships were placed along the Cinque Ports, but Portsmouth was also enlarged. By the end of 1204 he had around 50 large galleys available; another 54 vessels were built between 1209 and 1212. William of Wrotham was appointed "keeper of the galleys", effectively John's chief admiral. Wrotham was responsible for fusing John's galleys, the ships of the Cinque Ports and pressed merchant vessels into a single operational fleet. John adopted recent improvements in ship design, including new large transport ships called buisses and removable forecastles for use in combat.
How many galleys were available by the end of 1204?
Answer: 50

Question: The foundation of Northwestern University is traceable to a meeting on May 31, 1850 of nine prominent Chicago businessmen, Methodist leaders and attorneys who had formed the idea of establishing a university to serve what had once been known as the Northwest Territory. On January 28, 1851, the Illinois General Assembly granted a charter to the Trustees of the North-Western University, making it the first chartered university in Illinois. The school's nine founders, all of whom were Methodists (three of them ministers), knelt in prayer and worship before launching their first organizational meeting. Although they affiliated the university with the Methodist Episcopal Church, they were committed to non-sectarian admissions, believing that Northwestern should serve all people in the newly developing territory.
Is there an answer to this question: What denomination did the all of the founders disassociate with?

Answer:
unanswerable
