The concept of emissivity is important in understanding the infrared emissions of objects. This is a property of a surface that describes how its thermal emissions deviate from the ideal of a black body. To further explain, two objects at the same physical temperature will not show the same infrared image if they have differing emissivity. For example, for any pre-set emissivity value, objects with higher emissivity will appear hotter, and those with a lower emissivity will appear cooler. For that reason, incorrect selection of emissivity will give inaccurate results when using infrared cameras and pyrometers.
What is the term for the property that describes how a surface's thermal emissions deviate from the ideal of a black body?
emissivity

Input: Modern history
However, the crisis did not exist in a void; it came after a long series of diplomatic clashes between the Great Powers over European and colonial issues in the decade prior to 1914 which had left tensions high. The diplomatic clashes can be traced to changes in the balance of power in Europe since 1870. An example is the Baghdad Railway which was planned to connect the Ottoman Empire cities of Konya and Baghdad with a line through modern-day Turkey, Syria and Iraq. The railway became a source of international disputes during the years immediately preceding World War I. Although it has been argued that they were resolved in 1914 before the war began, it has also been argued that the railroad was a cause of the First World War. Fundamentally the war was sparked by tensions over territory in the Balkans. Austria-Hungary competed with Serbia and Russia for territory and influence in the region and they pulled the rest of the great powers into the conflict through their various alliances and treaties. The Balkan Wars were two wars in South-eastern Europe in 19121913 in the course of which the Balkan League (Bulgaria, Montenegro, Greece, and Serbia) first captured Ottoman-held remaining part of Thessaly, Macedonia, Epirus, Albania and most of Thrace and then fell out over the division of the spoils, with incorporation of Romania this time.

Why did Albania fall out with Thessaly, Macedonia and Epirus?
Output: over the division of the spoils

Input: Article: In November, Seattle averages more rainfall than any other U.S. city of more than 250,000 people; it also ranks highly in winter precipitation. Conversely, the city receives some of the lowest precipitation amounts of any large city from June to September. Seattle is one of the five rainiest major U.S. cities as measured by the number of days with precipitation, and it receives some of the lowest amounts of annual sunshine among major cities in the lower 48 states, along with some cities in the Northeast, Ohio and Michigan. Thunderstorms are rare, as the city reports thunder on just seven days per year. By comparison, Fort Myers, Florida reports thunder on 93 days per year, Kansas City on 52, and New York City on 25.

Now answer this question: What weather feature is highly unusual in Seattle?

Output: Thunderstorms

Article: It is very rare for top clubs to miss the competition, although it can happen in exceptional circumstances. Defending holders Manchester United did not enter the 19992000 FA Cup, as they were already in the inaugural Club World Championship, with the club stating that entering both tournaments would overload their fixture schedule and make it more difficult to defend their Champions League and Premiership titles. The club claimed that they did not want to devalue the FA Cup by fielding a weaker side. The move benefited United as they received a two-week break and won the 19992000 league title by an 18-point margin, although they did not progress past the group stage of the Club World Championship. The withdrawal from the FA Cup, however, drew considerable criticism as this weakened the tournament's prestige and Sir Alex Ferguson later admitted his regret regarding their handling of the situation.

Question: How did people feel about Manchester's decision?
Ans: drew considerable criticism as this weakened the tournament's prestige

Here is a question about this article: Left-wing politics have been particularly strong in municipal government since the 1960s. Voters approved charter amendments that have lessened the penalties for possession of marijuana (1974), and that aim to protect access to abortion in the city should it ever become illegal in the State of Michigan (1990). In 1974, Kathy Kozachenko's victory in an Ann Arbor city-council race made her the country's first openly homosexual candidate to win public office. In 1975, Ann Arbor became the first U.S. city to use instant-runoff voting for a mayoral race. Adopted through a ballot initiative sponsored by the local Human Rights Party, which feared a splintering of the liberal vote, the process was repealed in 1976 after use in only one election. As of August 2009, Democrats hold the mayorship and all council seats. The left tilt of politics in the city has earned it the nickname "The People's Republic of Ann Arbor". Nationally, Ann Arbor is located in Michigan's 12th congressional district, represented by Democrat Debbie Dingell.
What is the answer to this question: Voters in the city approve which kind of amendment?
****
So... charter

Article: On 14 June 1925, in a spontaneous reaction against Primo de Rivera's dictatorship, the crowd in the stadium jeered the Royal March. As a reprisal, the ground was closed for six months and Gamper was forced to relinquish the presidency of the club. This coincided with the transition to professional football, and, in 1926, the directors of Barcelona publicly claimed, for the first time, to operate a professional football club. On 3 July 1927, the club held a second testimonial match for Paulino Alcantara, against the Spanish national team. To kick off the match, local journalist and pilot Josep Canudas dropped the ball onto the pitch from his airplane. In 1928, victory in the Spanish Cup was celebrated with a poem titled "Oda a Platko", which was written by a member of the Generation of '27, Rafael Alberti, inspired by the heroic performance of the Barcelona goalkeeper, Franz Platko. On 23 June 1929, Barcelona won the inaugural Spanish League. A year after winning the championship, on 30 July 1930, Gamper committed suicide after a period of depression brought on by personal and financial problems.

Question: What past president of the Barcelona club committed suicide in 1930?
Ans:
Gamper
