instruction:

question:
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.
answer:
BBC


question:
What is the most common way to transmit email?, Context: Many mailbox providers are also access providers, while others are not (e.g., Yahoo! Mail, Outlook.com, Gmail, AOL Mail, Po box). The definition given in RFC 6650 covers email hosting services, as well as the relevant department of companies, universities, organizations, groups, and individuals that manage their mail servers themselves. The task is typically accomplished by implementing Simple Mail Transfer Protocol (SMTP) and possibly providing access to messages through Internet Message Access Protocol (IMAP), the Post Office Protocol, Webmail, or a proprietary protocol.
answer:
(SMTP)


question:
Which of the following is not a disputed territory: the Gaza Strip, the Second Intifada or the West Bank?, Context: After the collapse of the talks and a controversial visit by Likud leader Ariel Sharon to the Temple Mount, the Second Intifada began. Some commentators contend that the uprising was pre-planned by Yasser Arafat due to the collapse of peace talks. Sharon became prime minister in a 2001 special election. During his tenure, Sharon carried out his plan to unilaterally withdraw from the Gaza Strip and also spearheaded the construction of the Israeli West Bank barrier, ending the Intifada. By this time 1,100 Israelis had been killed, mostly in suicide bombings. The Palestinian fatalities, by 30 April 2008, reached 4,745 killed by Israeli security forces, 44 killed by Israeli civilians, and 577 killed by Palestinians.
answer:

Second Intifada
