Input: Read this: UN aerial reconnaissance had difficulty sighting PVA units in daytime, because their march and bivouac discipline minimized aerial detection. The PVA marched "dark-to-dark" (19:0003:00), and aerial camouflage (concealing soldiers, pack animals, and equipment) was deployed by 05:30. Meanwhile, daylight advance parties scouted for the next bivouac site. During daylight activity or marching, soldiers were to remain motionless if an aircraft appeared, until it flew away; PVA officers were under order to shoot security violators. Such battlefield discipline allowed a three-division army to march the 286 miles (460 km) from An-tung, Manchuria, to the combat zone in some 19 days. Another division night-marched a circuitous mountain route, averaging 18 miles (29 km) daily for 18 days.
Question: What were PVA officers supposed to do if troops disobeyed the security protocol?

Output: shoot security violators

Input: Read this: In its 2014 Press Freedom Index, Reporters Without Borders ranked the media environment in Eritrea at the very bottom of a list of 178 countries, just below totalitarian North Korea. According to the BBC, "Eritrea is the only African country to have no privately owned news media", and Reporters Without Borders said of the public media, "[they] do nothing but relay the regime's belligerent and ultra-nationalist discourse. ... Not a single [foreign correspondent] now lives in Asmara." The state-owned news agency censors news about external events. Independent media have been banned since 2001. In 2015, The Guardian published an opinion piece claiming,
Question: What type of media has been banned from Eritrea since 2001?

Input: Read this: Occasional severe flooding is experienced. There was the Great Mississippi Flood of 1927, the Great Flood of 1993, and widespread flooding and mudslides caused by the 1982-1983 El Nino event in the western United States. Localized flooding can, however, occur anywhere, and mudslides from heavy rain can cause problems in any mountainous area, particularly the Southwest. Large stretches of desert shrub in the west can fuel the spread of wildfires. The narrow canyons of many mountain areas in the west and severe thunderstorm activity during the summer lead to sometimes devastating flash floods as well, while Nor'Easter snowstorms can bring activity to a halt throughout the Northeast (although heavy snowstorms can occur almost anywhere).
Question: What is the name of the major event that caused flooding in the eastern United States?

Output: unanswerable

Input: Read this: One of the first victims was Northern Rock, a medium-sized British bank. The highly leveraged nature of its business led the bank to request security from the Bank of England. This in turn led to investor panic and a bank run in mid-September 2007. Calls by Liberal Democrat Treasury Spokesman Vince Cable to nationalise the institution were initially ignored; in February 2008, however, the British government (having failed to find a private sector buyer) relented, and the bank was taken into public hands. Northern Rock's problems proved to be an early indication of the troubles that would soon befall other banks and financial institutions.
Question: When did Northern Rock investors panic and a bank run begin?

Output:
September 2007
