Ex Input:
What channel claimed that there had once been a civilization in the Amazon rainforest?, Context: The first European to travel the length of the Amazon River was Francisco de Orellana in 1542. The BBC's Unnatural Histories presents evidence that Orellana, rather than exaggerating his claims as previously thought, was correct in his observations that a complex civilization was flourishing along the Amazon in the 1540s. It is believed that the civilization was later devastated by the spread of diseases from Europe, such as smallpox. Since the 1970s, numerous geoglyphs have been discovered on deforested land dating between AD 0–1250, furthering claims about Pre-Columbian civilizations. Ondemar Dias is accredited with first discovering the geoglyphs in 1977 and Alceu Ranzi with furthering their discovery after flying over Acre. The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Ex Input:
What styles influenced the styles used in the region?, Context: Increasing military and cultural contacts with the Muslim world, including the Norman conquest of Islamic Sicily in 1090, the Crusades, beginning 1096, and the Islamic presence in Spain, may have influenced Medieval Europe's adoption of the pointed arch, although this hypothesis remains controversial. Certainly, in those parts of the Western Mediterranean subject to Islamic control or influence, rich regional variants arose, fusing Romanesque and later Gothic traditions with Islamic decorative forms, as seen, for example, in Monreale and Cefalù Cathedrals, the Alcázar of Seville, and Teruel Cathedral.

Ex Output:
Gothic traditions with Islamic decorative forms


Ex Input:
Which of the following is not one of the causes of the bank failure: bad investments, a bailout or embezzlement?, Context: After the financial crisis of 2007–08, it was known in 2008–2009 that two Portuguese banks (Banco Português de Negócios (BPN) and Banco Privado Português (BPP)) had been accumulating losses for years due to bad investments, embezzlement and accounting fraud. The case of BPN was particularly serious because of its size, market share, and the political implications - Portugal's then current President, Cavaco Silva, and some of his political allies, maintained personal and business relationships with the bank and its CEO, who was eventually charged and arrested for fraud and other crimes. In the grounds of avoiding a potentially serious financial crisis in the Portuguese economy, the Portuguese government decided to give them a bailout, eventually at a future loss to taxpayers and to the Portuguese people in general.

Ex Output:
a bailout
