Problem: Computer:

A key component common to all CPUs is the program counter, a special memory cell (a register) that keeps track of which location in memory the next instruction is to be read from.

Problem: Of major Canadian cities, St. John's is the foggiest (124 days), windiest (24.3 km/h (15.1 mph) average speed), and cloudiest (1,497 hours of sunshine). St. John's experiences milder temperatures during the winter season in comparison to other Canadian cities, and has the mildest winter for any Canadian city outside of British Columbia. Precipitation is frequent and often heavy, falling year round. On average, summer is the driest season, with only occasional thunderstorm activity, and the wettest months are from October to January, with December the wettest single month, with nearly 165 millimetres of precipitation on average. This winter precipitation maximum is quite unusual for humid continental climates, which most commonly have a late spring or early summer precipitation maximum (for example, most of the Midwestern U.S.). Most heavy precipitation events in St. John's are the product of intense mid-latitude storms migrating from the Northeastern U.S. and New England states, and these are most common and intense from October to March, bringing heavy precipitation (commonly 4 to 8 centimetres of rainfall equivalent in a single storm), and strong winds. In winter, two or more types of precipitation (rain, freezing rain, sleet and snow) can fall from passage of a single storm. Snowfall is heavy, averaging nearly 335 centimetres per winter season. However, winter storms can bring changing precipitation types. Heavy snow can transition to heavy rain, melting the snow cover, and possibly back to snow or ice (perhaps briefly) all in the same storm, resulting in little or no net snow accumulation. Snow cover in St. John's is variable, and especially early in the winter season, may be slow to develop, but can extend deeply into the spring months (March, April). The St. John's area is subject to freezing rain (called "silver thaws"), the worst of which paralyzed the city over a three-day period in April 1984.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1922 the British Empire held sway over about 458 million people, one-fifth of the world's population at the time, and covered more than 13,000,000 sq mi (33,670,000 km2), almost a quarter of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.
How much of the world's population did the British Empire rule in 1922?
A: one-fifth


Context and question: Holt increased Australian commitment to the growing War in Vietnam, which met with some public opposition. His government oversaw conversion to decimal currency. Holt faced Britain's withdrawal from Asia by visiting and hosting many Asian leaders and by expanding ties to the United States, hosting the first visit to Australia by an American president, his friend Lyndon B. Johnson. Holt's government introduced the Migration Act 1966, which effectively dismantled the White Australia Policy and increased access to non-European migrants, including refugees fleeing the Vietnam War. Holt also called the 1967 Referendum which removed the discriminatory clause in the Australian Constitution which excluded Aboriginal Australians from being counted in the census – the referendum was one of the few to be overwhelmingly endorsed by the Australian electorate (over 90% voted 'yes'). By the end of 1967, the Liberals' initially popular support for the war in Vietnam was causing increasing public protest.
Which of Holt's stances received some public opposition?
Answer: commitment to the growing War in Vietnam


Question: Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid 1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.
Is there an answer to this question: This decision reflected a revision of what?

Answer: the ASME A17.1


The Iranian languages or Iranic languages form a branch of the Indo-Iranian languages, which in turn are a branch of the Indo-European language family. The speakers of Iranian languages are known as Iranian peoples. Historical Iranian languages are grouped in three stages: Old Iranian (until 400 BCE), Middle Iranian (400 BCE – 900 CE), and New Iranian (since 900 CE). Of the Old Iranian languages, the better understood and recorded ones are Old Persian (a language of Achaemenid Iran) and Avestan (the language of the Avesta). Middle Iranian languages included Middle Persian (a language of Sassanid Iran), Parthian, and Bactrian.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are Indo-Iranian languages a subset of?
Ah, so..
Indo-European language family
