Problem: Please answer a question about the following article about London:
The Vikings established Danelaw over much of the eastern and northern part of England with its boundary roughly stretching from London to Chester. It was an area of political and geographical control imposed by the Viking incursions which was formally agreed to by the Danish warlord, Guthrum and west-Saxon king, Alfred the Great in 886 AD. The Anglo-Saxon Chronicle recorded that London was "refounded" by Alfred the Great in 886. Archaeological research shows that this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls. London then grew slowly until about 950, after which activity increased dramatically.
What was Danelaw?
A: political and geographical control imposed by the Viking incursions
Problem: Please answer a question about the following article about Philosophy of space and time:
But in statistical mechanics things get more complicated. On one hand, statistical mechanics is far superior to classical thermodynamics, in that thermodynamic behavior, such as glass breaking, can be explained by the fundamental laws of physics paired with a statistical postulate. But statistical mechanics, unlike classical thermodynamics, is time-reversal symmetric. The second law of thermodynamics, as it arises in statistical mechanics, merely states that it is overwhelmingly likely that net entropy will increase, but it is not an absolute law.
Is statistical mechanics asymmetric or symmetric in regards to time-reversal?
A: symmetric
Problem: Please answer a question about the following article about Napoleon:
Napoleon was crowned Emperor Napoleon I on 2 December 1804 at Notre Dame de Paris by Pope Pius VII. On 1 April 1810, Napoleon religiously married the Austrian princess Marie Louise. During his brother's rule in Spain, he abolished the Spanish Inquisition in 1813. In a private discussion with general Gourgaud during his exile on Saint Helena, Napoleon expressed materialistic views on the origin of man,[note 9]and doubted the divinity of Jesus, stating that it is absurd to believe that Socrates, Plato, Muslims, and the Anglicans should be damned for not being Roman Catholics.[note 10] He also said to Gourgaud in 1817 "I like the Mohammedan religion best. It has fewer incredible things in it than ours." and that "the Mohammedan religion is the finest of all." However, Napoleon was anointed by a priest before his death.
When did Napoleon marry Marie Louise?
A: 1 April 1810
Problem: Please answer a question about the following article about High-definition television:
Since 1972, International Telecommunication Union's radio telecommunications sector (ITU-R) had been working on creating a global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 also led to the acceptance of recommendations ITU-R BT.709. In anticipation of these standards the Digital Video Broadcasting (DVB) organisation was formed, an alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI.
What is the DVB's role?
A:
develops and agrees upon specifications
