Input: Read this: 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.
Question: From where is the temperature of a glacier measured?

Output: base alone

QUES: The considerable spending did not lead to more growth and did not benefit the poor. Much of the increased spending has gone to current expenditures related to wages, transfers, and subsidies. The wage bill today constitutes over 15% of GDP and 55% of total public spending; these are some of the highest levels on the African continent. The recent rapid growth in SACU revenues has, however, reversed the fiscal situation, and a sizeable surplus was recorded since 2006. SACU revenues today account for over 60% of total government revenues. On the positive side, the external debt burden has declined markedly over the last 20 years, and domestic debt is almost negligible; external debt as a percent of GDP was less than 20% in 2006.

What has a decline in SACU revenues done?
What is the answer?
ANS: unanswerable

QUES: Unlike in Westminster style legislatures or as with the Senate Majority Leader, the House Majority Leader's duties and prominence vary depending upon the style and power of the Speaker of the House. Typically, the Speaker does not participate in debate and rarely votes on the floor. In some cases, Majority Leaders have been more influential than the Speaker; notably Tom DeLay who was more prominent than Speaker Dennis Hastert. In addition, Speaker Newt Gingrich delegated to Dick Armey an unprecedented level of authority over scheduling legislation on the House floor.
What did Tom Delay give Dick Armey the authority over on the House floor?

ANS: unanswerable

After Kim Jong Il, the second ruler of North Korea, died in December 2011, Kim Jong Un stepped up and began mandating the use of Hanja as a source of definition for the Korean language. Currently, it is said that North Korea teaches around 3,000 Hanja characters to North Korean students, and in some cases, the characters appear within advertisements and newspapers. However, it is also said that the authorities implore students not to use the characters in public. Due to North Korea's strict isolationism, accurate reports about hanja use in North Korea are hard to obtain.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the second ruler of North Korea pass away?
Ah, so.. December 2011

Question: Spectre had its world premiere in London on 26 October 2015 at the Royal Albert Hall, the same day as its general release in the United Kingdom and Republic of Ireland. Following the announcement of the start of filming, Paramount Pictures brought forward the release of Mission: Impossible Rogue Nation to avoid competing with Spectre. In March 2015 IMAX corporation announced that Spectre would be screened in its cinemas, following Skyfall's success with the company. In the UK it received a wider release than Skyfall, with a minimum of 647 cinemas including 40 IMAX screens, compared to Skyfall's 587 locations and 21 IMAX screens.
Try to answer this question if possible: On what date was Spectre first shown for general audiences?
Answer: 26 October 2015

Question: The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.
Try to answer this question if possible: What invention allowed horses rather than oxen to be used to plow?
Answer:
the horse collar
