input question: Question: "What the settlement that is now the capital of the land now ruled by Elizabeth II was effectively refounded by a ruler from the western part of an area in eastern Germany?" Context: "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." Answer:???
output answer: London

Question: "What happens when something changes in the system?" Context: "Analysis of lighting quality particularly emphasizes use of natural lighting, but also considers spectral content if artificial light is to be used. Not only will greater reliance on natural light reduce energy consumption, but will favorably impact human health and performance. New studies have shown that the performance of students is influenced by the time and duration of daylight in their regular schedules. Designing school facilities to incorporate the right types of light at the right time of day for the right duration may improve student performance and well-being. Similarly, designing lighting systems that maximize the right amount of light at the appropriate time of day for the elderly may help relieve symptoms of Alzheimer's Disease. The human circadian system is entrained to a 24-hour light-dark pattern that mimics the earth's natural light/dark pattern. When those patterns are disrupted, they disrupt the natural circadian cycle. Circadian disruption may lead to numerous health problems including breast cancer, seasonal affective disorder, delayed sleep phase syndrome, and other ailments." Answer:
----
Answer: disruption may lead to numerous health problems including breast cancer, seasonal affective disorder, delayed sleep phase syndrome, and other ailments

Q: Question: "what is the first nation mentioned?" Context: "Cork was one of the most rail-oriented cities in Ireland, featuring eight stations at various times. The main route, still much the same today, is from Dublin Heuston. Originally terminating on the city's outskirts at Blackpool, the route now reaches the city centre terminus of Kent Station via Glanmire tunnel. Now a through station, the line through Kent connects the towns of Cobh and Midleton east of the city. This also connected to the seaside town of Youghal, until the 1980s.[citation needed]" Answer:
A: Ireland

The "All-India Sanskrit Festival" (since 2002) holds composition contests. The 1991 Indian census reported 49,736 fluent speakers of Sanskrit. Sanskrit learning programmes also feature on the lists of most AIR broadcasting centres. The Mattur village in central Karnataka claims to have native speakers of Sanskrit among its population. Inhabitants of all castes learn Sanskrit starting in childhood and converse in the language. Even the local Muslims converse in Sanskrit. Historically, the village was given by king Krishnadevaraya of the Vijayanagara Empire to Vedic scholars and their families, while people in his kingdom spoke Kannada and Telugu. Another effort concentrates on preserving and passing along the oral tradition of the Vedas, www.shrivedabharathi.in is one such organisation based out of Hyderabad that has been digitising the Vedas by recording recitations of Vedic Pandits." Answer:

[A]: India

Problem: Given the question: Question: "What must physical action be in classical statistical mechanics?" Context: "Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden." Answer:
++++++++++++++++++++++++++++++++
The answer is:
some multiple of a very small quantity
