Problem: London:

The administration of London is formed of two tiersa city-wide, strategic tier and a local tier. City-wide administration is coordinated by the Greater London Authority (GLA), while local administration is carried out by 33 smaller authorities. The GLA consists of two elected components; the Mayor of London, who has executive powers, and the London Assembly, which scrutinises the mayor's decisions and can accept or reject the mayor's budget proposals each year. The headquarters of the GLA is City Hall, Southwark; the mayor is Boris Johnson. The mayor's statutory planning strategy is published as the London Plan, which was most recently revised in 2011. The local authorities are the councils of the 32 London boroughs and the City of London Corporation. They are responsible for most local services, such as local planning, schools, social services, local roads and refuse collection. Certain functions, such as waste management, are provided through joint arrangements. In 20092010 the combined revenue expenditure by London councils and the GLA amounted to just over 22 billion (14.7 billion for the boroughs and 7.4 billion for the GLA).

Problem: Whitehead and Russell had thought originally that Principia Mathematica would take a year to complete; it ended up taking them ten years. To add insult to injury, when it came time for publication, the three-volume work was so massive (more than 2,000 pages) and its audience so narrow (professional mathematicians) that it was initially published at a loss of 600 pounds, 300 of which was paid by Cambridge University Press, 200 by the Royal Society of London, and 50 apiece by Whitehead and Russell themselves. Despite the initial loss, today there is likely no major academic library in the world which does not hold a copy of Principia Mathematica.
Why was there a funding shortfall for the publishing of Princpia Mathematica?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Punjab witnessed major battles between the armies of India and Pakistan in the wars of 1965 and 1971. Since the 1990s Punjab hosted several key sites of Pakistan's nuclear program such as Kahuta. It also hosts major military bases such as at Sargodha and Rawalpindi. The peace process between India and Pakistan, which began in earnest in 2004, has helped pacify the situation. Trade and people-to-people contacts through the Wagah border are now starting to become common. Indian Sikh pilgrims visit holy sites such as Nankana Sahib.
Who visits Nankana Sahib?

Context and question: Definitions of literature have varied over time; it is a "culturally relative definition". In Western Europe prior to the eighteenth century, literature as a term indicated all books and writing. A more restricted sense of the term emerged during the Romantic period, in which it began to demarcate "imaginative" literature. Contemporary debates over what constitutes literature can be seen as returning to the older, more inclusive notion of what constitutes literature. Cultural studies, for instance, takes as its subject of analysis both popular and minority genres, in addition to canonical works.
During that 18th century period, literature began to be applied how?
Answer: it began to demarcate "imaginative" literature

Question: In October 2004, Sarah Forsyth claimed that she had been dismissed unfairly by Eton College and had been bullied by senior staff. She also claimed she was instructed to do some of Prince Harry's coursework to enable him to pass AS Art. As evidence, Forsyth provided secretly recorded conversations with both Prince Harry and her Head of Department, Ian Burke. An employment tribunal in July 2005 found that she had been unfairly dismissed and criticised Burke for bullying her and for repeatedly changing his story. It also criticised the school for failing to produce its capability procedures and criticised the Head Master for not reviewing the case independently.
Is there an answer to this question: What position did Sarah Forsyth have at Eton in 2004?

Answer: unanswerable

According to the Office for National Statistics, at the 2001 census there were over a million black people in the United Kingdom; 1% of the total population described themselves as "Black Caribbean", 0.8% as "Black African", and 0.2% as "Black other". Britain encouraged the immigration of workers from the Caribbean after World War II; the first symbolic movement was those who came on the ship the Empire Windrush. The preferred official umbrella term is "black and minority ethnic" (BME), but sometimes the term "black" is used on its own, to express unified opposition to racism, as in the Southall Black Sisters, which started with a mainly British Asian constituency, and the National Black Police Association, which has a membership of "African, African-Caribbean and Asian origin".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In 2001 how many black people lived in the UK?
Ah, so..
over a million black
