Problem: Glacier:

Thermally, a temperate glacier is at melting point throughout the year, from its surface to its base. The ice of a polar glacier is always below freezing point from the surface to its base, although the surface snowpack may experience seasonal melting. A sub-polar glacier includes both temperate and polar ice, depending on depth beneath the surface and position along the length of the glacier. In a similar way, the thermal regime of a glacier is often described by the temperature at its base alone. A cold-based glacier is below freezing at the ice-ground interface, and is thus frozen to the underlying substrate. A warm-based glacier is above or at freezing at the interface, and is able to slide at this contact. This contrast is thought to a large extent to govern the ability of a glacier to effectively erode its bed, as sliding ice promotes plucking at rock from the surface below. Glaciers which are partly cold-based and partly warm-based are known as polythermal.

What temperature makes a glacier polythermal?

A: partly cold-based and partly warm-based

Problem: The political separation of the Church of England from Rome under Henry VIII brought England alongside this broad Reformation movement. Reformers in the Church of England alternated between sympathies for ancient Catholic tradition and more Reformed principles, gradually developing into a tradition considered a middle way (via media) between the Roman Catholic and Protestant traditions. The English Reformation followed a particular course. The different character of the English Reformation came primarily from the fact that it was driven initially by the political necessities of Henry VIII. King Henry decided to remove the Church of England from the authority of Rome. In 1534, the Act of Supremacy recognized Henry as the only Supreme Head on earth of the Church of England. Between 1535 and 1540, under Thomas Cromwell, the policy known as the Dissolution of the Monasteries was put into effect. Following a brief Roman Catholic restoration during the reign of Mary I, a loose consensus developed during the reign of Elizabeth I. The Elizabethan Religious Settlement largely formed Anglicanism into a distinctive church tradition. The compromise was uneasy and was capable of veering between extreme Calvinism on the one hand and Roman Catholicism on the other. It was relatively successful until the Puritan Revolution or English Civil War in the 17th century.
Who was made the Supreme Head of the Church of England in 1534?

Many beers are sold in cans, though there is considerable variation in the proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing "skunked" beer) and have a seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic (PET) bottles are used by some breweries.
What major sporting event was held in 2001?
A: unanswerable

Context and question: The process of making beer is known as brewing. A dedicated building for the making of beer is called a brewery, though beer can be made in the home and has been for much of its history. A company that makes beer is called either a brewery or a brewing company. Beer made on a domestic scale for non-commercial reasons is classified as homebrewing regardless of where it is made, though most homebrewed beer is made in the home. Brewing beer is subject to legislation and taxation in developed countries, which from the late 19th century largely restricted brewing to a commercial operation only. However, the UK government relaxed legislation in 1963, followed by Australia in 1972 and the US in 1978, allowing homebrewing to become a popular hobby.
What became a hobby in the US due to relaxed laws in 1987?
Answer: unanswerable

Question: Energy sources unsuitable for mobile power plants, such as nuclear power, renewable hydroelectricity, or wind power can be used. According to widely accepted global energy reserve statistics, the reserves of liquid fuel are much less than gas and coal (at 42, 167 and 416 years respectively). Most countries with large rail networks do not have significant oil reserves and those that did, like the United States and Britain, have exhausted much of their reserves and have suffered declining oil output for decades. Therefore, there is also a strong economic incentive to substitute other fuels for oil. Rail electrification is often considered an important route towards consumption pattern reform. However, there are no reliable, peer-reviewed studies available to assist in rational public debate on this critical issue, although there are untranslated Soviet studies from the 1980s.
Is there an answer to this question: Most countries with small rail networks do not have what?

Answer: unanswerable
