question:
Can BskyB refuse service to any entity?, Context: BSkyB has no veto over the presence of channels on their EPG, with open access being an enforced part of their operating licence from Ofcom. Any channel which can get carriage on a suitable beam of a satellite at 28 East is entitled to access to BSkyB's EPG for a fee, ranging from 15100,000. Third-party channels which opt for encryption receive discounts ranging from reduced price to free EPG entries, free carriage on a BSkyB leased transponder, or actual payment for being carried. However, even in this case, BSkyB does not carry any control over the channel's content or carriage issues such as picture quality.
answer:
BSkyB has no veto over the presence of channels

question:
Polytechnics generally focused on what in the beginning?, Context: Polytechnics were tertiary education teaching institutions in England, Wales and Northern Ireland. Since 1970 UK Polytechnics operated under the binary system of education along with universities. Polytechnics offered diplomas and degrees (bachelor's, master's, PhD) validated at the national level by the UK Council for National Academic Awards CNAA. They particularly excelled in engineering and applied science degree courses similar to technological universities in the USA and continental Europe. The comparable institutions in Scotland were collectively referred to as Central Institutions. Britain's first Polytechnic, the Royal Polytechnic Institution later known as the Polytechnic of Central London (now the University of Westminster) was established in 1838 at Regent Street in London and its goal was to educate and popularize engineering and scientific knowledge and inventions in Victorian Britain "at little expense." The London Polytechnic led a mass movement to create numerous Polytechnic institutes across the UK in the late 19th Century. Most Polytechnic institutes were established at the centre of major metropolitan cities and their focus was on engineering, applied science and technology education.
answer:
engineering, applied science and technology education

question:
Which is smaller, viruses or human nerves?, Context: Persistent infections occur because the body is unable to clear the organism after the initial infection. Persistent infections are characterized by the continual presence of the infectious organism, often as latent infection with occasional recurrent relapses of active infection. There are some viruses that can maintain a persistent infection by infecting different cells of the body. Some viruses once acquired never leave the body. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise.
answer:
viruses
