Problem: Please answer a question about the following article about Brain:
As a side effect of the electrochemical processes used by neurons for signaling, brain tissue generates electric fields when it is active. When large numbers of neurons show synchronized activity, the electric fields that they generate can be large enough to detect outside the skull, using electroencephalography (EEG) or magnetoencephalography (MEG). EEG recordings, along with recordings made from electrodes implanted inside the brains of animals such as rats, show that the brain of a living animal is constantly active, even during sleep. Each part of the brain shows a mixture of rhythmic and nonrhythmic activity, which may vary according to behavioral state. In mammals, the cerebral cortex tends to show large slow delta waves during sleep, faster alpha waves when the animal is awake but inattentive, and chaotic-looking irregular activity when the animal is actively engaged in a task. During an epileptic seizure, the brain's inhibitory control mechanisms fail to function and electrical activity rises to pathological levels, producing EEG traces that show large wave and spike patterns not seen in a healthy brain. Relating these population-level patterns to the computational functions of individual neurons is a major focus of current research in neurophysiology.
MEG of the brain is an abbreviation of what?
A: magnetoencephalography

In the early 20th century Valencia was an industrialised city. The silk industry had disappeared, but there was a large production of hides and skins, wood, metals and foodstuffs, this last with substantial exports, particularly of wine and citrus. Small businesses predominated, but with the rapid mechanisation of industry larger companies were being formed. The best expression of this dynamic was in the regional exhibitions, including that of 1909 held next to the pedestrian avenue L'Albereda (Paseo de la Alameda), which depicted the progress of agriculture and industry. Among the most architecturally successful buildings of the era were those designed in the Art Nouveau style, such as the North Station (Gare du Nord) and the Central and Columbus markets.

When was an exhibition held that showed agricultural and industrial progress?
Answer: 1909

Problem: On July 20, 2009, Sports Business Journal reported that the AFL owed approximately $14 million to its creditors and were considering filing for Chapter 11 bankruptcy protection. In early August 2009, numerous media outlets began reporting that the AFL was folding permanently and would file for Chapter 7 bankruptcy. The league released a statement on August 4 to the effect that while the league was not folding, it was suspending league operations indefinitely. Despite this, several of the league's creditors filed papers to force a Chapter 7 liquidation if the league did not do so voluntarily. This request was granted on August 7, though converted to a Chapter 11 reorganization on August 26.
On what date did the AFL announce that it was not shutting down?
The answer is the following: August 4

In the north, the Republic of Novgorod prospered because it controlled trade routes from the River Volga to the Baltic Sea. As Kievan Rus' declined, Novgorod became more independent. A local oligarchy ruled Novgorod; major government decisions were made by a town assembly, which also elected a prince as the city's military leader. In the 12th century, Novgorod acquired its own archbishop Ilya in 1169, a sign of increased importance and political independence, while about 30 years prior to that in 1136 in Novgorod was established a republican form of government - elective monarchy. Since then Novgorod enjoyed a wide degree of autonomy although being closely associated with the Kievan Rus.
What happened to Novgorod when Kievan Rus began to decline?
became more independent

Input: Videoconferencing
One of the first demonstrations of the ability for telecommunications to help sign language users communicate with each other occurred when AT&T's videophone (trademarked as the "Picturephone") was introduced to the public at the 1964 New York World's Fair two deaf users were able to communicate freely with each other between the fair and another city. Various universities and other organizations, including British Telecom's Martlesham facility, have also conducted extensive research on signing via videotelephony. The use of sign language via videotelephony was hampered for many years due to the difficulty of its use over slow analogue copper phone lines, coupled with the high cost of better quality ISDN (data) phone lines. Those factors largely disappeared with the introduction of more efficient video codecs and the advent of lower cost high-speed ISDN data and IP (Internet) services in the 1990s.

What company introduced the first device to help deaf people communicate through telecommunications?
Output: AT&T

Problem: Please answer a question about the following article about Poultry:
The modern domesticated turkey is descended from one of six subspecies of wild turkey (Meleagris gallopavo) found in the present Mexican states of Jalisco, Guerrero and Veracruz. Pre-Aztec tribes in south-central Mexico first domesticated the bird around 800 BC, and Pueblo Indians inhabiting the Colorado Plateau in the United States did likewise around 200 BC. They used the feathers for robes, blankets, and ceremonial purposes. More than 1,000 years later, they became an important food source. The first Europeans to encounter the bird misidentified it as a guineafowl, a bird known as a "turkey fowl" at that time because it had been introduced into Europe via Turkey.
When and with what culture did domesticated turkey start to appear in the United States ?
A:
Pueblo Indians inhabiting the Colorado Plateau in the United States did likewise around 200 BC.
