Problem: Pain:

Wilhelm Erb's (1874) "intensive" theory, that a pain signal can be generated by intense enough stimulation of any sensory receptor, has been soundly disproved. Some sensory fibers do not differentiate between noxious and non-noxious stimuli, while others, nociceptors, respond only to noxious, high intensity stimuli. At the peripheral end of the nociceptor, noxious stimuli generate currents that, above a given threshold, begin to send signals along the nerve fiber to the spinal cord. The "specificity" (whether it responds to thermal, chemical or mechanical features of its environment) of a nociceptor is determined by which ion channels it expresses at its peripheral end. Dozens of different types of nociceptor ion channels have so far been identified, and their exact functions are still being determined.

What is Erb Wilhelm's intensive theory?

Problem: Labour Party (UK):

Fear of advances by the nationalist parties, particularly in Scotland, led to the suppression of a report from Scottish Office economist Gavin McCrone that suggested that an independent Scotland would be 'chronically in surplus'. By 1977 by-election losses and defections to the breakaway Scottish Labour Party left Callaghan heading a minority government, forced to trade with smaller parties in order to govern. An arrangement negotiated in 1977 with Liberal leader David Steel, known as the Lib-Lab Pact, ended after one year. Deals were then forged with various small parties including the Scottish National Party and the Welsh nationalist Plaid Cymru, prolonging the life of the government.

What arrangement lasted longer than one year?

A: unanswerable

Problem: Compact disc:

SVCD has two-thirds the resolution of DVD, and over 2.7 times the resolution of VCD. One CD-R disc can hold up to 60 minutes of standard quality SVCD-format video. While no specific limit on SVCD video length is mandated by the specification, one must lower the video bit rate, and therefore quality, to accommodate very long videos. It is usually difficult to fit much more than 100 minutes of video onto one SVCD without incurring significant quality loss, and many hardware players are unable to play video with an instantaneous bit rate lower than 300 to 600 kilobits per second.

Why is it difficult to put more than 60 minutes on a DVD?

A: unanswerable

Problem: Cyprus:

The Turkish invasion, followed by occupation and the declaration of independence of the TRNC have been condemned by United Nations resolutions, which are reaffirmed by the Security Council every year. The last major effort to settle the Cyprus dispute was the Annan Plan in 2004, drafted by the then Secretary General, Kofi Annan. The plan was put to a referendum in both Northern Cyprus and the Republic of Cyprus. 65% of Turkish Cypriots voted in support of the plan and 74% Greek Cypriots voted against the plan, claiming that it disproportionately favoured the Turkish side. In total, 66.7% of the voters rejected the Annan Plan V. On 1 May 2004 Cyprus joined the European Union, together with nine other countries. Cyprus was accepted into the EU as a whole, although the EU legislation is suspended in the territory occupied by Turkey (TRNC), until a final settlement of the Cyprus problem. In July 2006, the island served as a haven for people fleeing Lebanon, due to the conflict between Israel and Hezbollah (also called "The July War").

In 2006 people fled to Cyprus from what country?

A:
Lebanon
