Problem: Central African Republic:

Patasse purged many of the Kolingba elements from the government and Kolingba supporters accused Patasse's government of conducting a "witch hunt" against the Yakoma. A new constitution was approved on 28 December 1994 but had little impact on the country's politics. In 19961997, reflecting steadily decreasing public confidence in the government's erratic behaviour, three mutinies against Patasse's administration were accompanied by widespread destruction of property and heightened ethnic tension. During this time (1996) the Peace Corps evacuated all its volunteers to neighboring Cameroon. To date, the Peace Corps has not returned to the Central African Republic. The Bangui Agreements, signed in January 1997, provided for the deployment of an inter-African military mission, to Central African Republic and re-entry of ex-mutineers into the government on 7 April 1997. The inter-African military mission was later replaced by a U.N. peacekeeping force (MINURCA).

As of today what group has not returned to Yakoma?

A: unanswerable

Problem: Thuringia:

Thuringia generally accepted the Protestant Reformation, and Roman Catholicism was suppressed as early as 1520[citation needed]; priests who remained loyal to it were driven away and churches and monasteries were largely destroyed, especially during the German Peasants' War of 1525. In Muhlhausen and elsewhere, the Anabaptists found many adherents. Thomas Muntzer, a leader of some non-peaceful groups of this sect, was active in this city. Within the borders of modern Thuringia the Roman Catholic faith only survived in the Eichsfeld district, which was ruled by the Archbishop of Mainz, and to a small degree in Erfurt and its immediate vicinity.

Who was Thomas Muntzer?
---
A: a leader of some non-peaceful groups

Problem: Serbo-Croatian:

Enisa Kafadar argues that there is only one Serbo-Croatian language with several varieties. This has made possible to include all four varieties into a new grammar book. Daniel Buncic concludes that it is a pluricentric language, with four standard variants spoken in Serbia, Croatia, Montenegro and Bosnia and Herzegovina. The mutual intelligibility between their speakers "exceeds that between the standard variants of English, French, German, or Spanish". Other linguists have argued that the differences between the variants of Serbo-Croatian are less significant than those between the variants of English, German,, Dutch, and Hindi-Urdu.

How many standard variants of the Serbo-Croatian are spoken?
---
A: four

Problem: Royal Dutch Shell:

In February 2010 Shell and Cosan formed a 50:50 joint-venture, Raizen, comprising all of Cosan's Brazilian ethanol, energy generation, fuel distribution and sugar activities, and all of Shell's Brazilian retail fuel and aviation distribution businesses. In March 2010, Shell announced the sale of some of its assets, including its liquid petroleum gas (LPG) business, to meet the cost of a planned $28bn capital spending programme. Shell invited buyers to submit indicative bids, due by 22 March, with a plan to raise $23bn from the sale. In June 2010, Royal Dutch Shell agreed to acquire all the business of East Resources for a cash consideration of $4.7 billion. The transaction included East Resources' tight gas fields.

Why did Shell sell some of its assets in March 2010?
