Problem: Greeks:

Most Greeks are Christians, belonging to the Greek Orthodox Church. During the first centuries after Jesus Christ, the New Testament was originally written in Koine Greek, which remains the liturgical language of the Greek Orthodox Church, and most of the early Christians and Church Fathers were Greek-speaking. There are small groups of ethnic Greeks adhering to other Christian denominations like Greek Catholics, Greek Evangelicals, Pentecostals, and groups adhering to other religions including Romaniot and Sephardic Jews and Greek Muslims. About 2,000 Greeks are members of Hellenic Polytheistic Reconstructionism congregations.

This language is the official dialect of worship for the traditional sect for church worshipers of Greece ?

Problem: The Chicago White Stockings, (today's Chicago Cubs), began spring training in Hot Springs, Arkansas in 1886. President Albert Spalding (founder of Spalding Sporting Goods) and player/manager Cap Anson brought their players to Hot Springs and played at the Hot Springs Baseball Grounds. The concept was for the players to have training and fitness before the start of the regular season. After the White Stockings had a successful season in 1886, winning the National League Pennant, other teams began bringing their players to "spring training". The Chicago Cubs, St. Louis Browns, New York Yankees, St. Louis Cardinals, Cleveland Spiders, Detroit Tigers, Pittsburgh Pirates, Cincinnati Reds, New York Highlanders, Brooklyn Dodgers and Boston Red Sox were among the early squads to arrive. Whittington Park (1894) and later Majestic Park (1909) and Fogel Field (1912) were all built in Hot Springs specifically to host Major League teams.
Who began spring training in Hot Springs, Arkansas in 1886?

The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can also occur. Early red LEDs were notable for their short service life. With the development of high-power LEDs the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantitatively classify useful lifetime in a standardized manner it has been suggested to use L70 or L50, which are the runtimes (typically given in thousands of hours) at which a given LED reaches 70% and 50% of initial light output, respectively.
What is rare in LED lighting?
A: Sudden failures

Context and question: It was not until 9 June 1982, with the Circulaire sur la langue et la culture regionales en Alsace (Memorandum on regional language and culture in Alsace) issued by the Vice-Chancellor of the Academie Pierre Deyon, that the teaching of German in primary schools in Alsace really began to be given more official status. The Ministerial Memorandum of 21 June 1982, known as the Circulaire Savary, introduced financial support, over three years, for the teaching of regional languages in schools and universities. This memorandum was, however, implemented in a fairly lax manner.
Who wrote the Circulaire Savary?
Answer: unanswerable

West of the Rocky Mountains lies the Intermontane Plateaus (also known as the Intermountain West), a large, arid desert lying between the Rockies and the Cascades and Sierra Nevada ranges. The large southern portion, known as the Great Basin, consists of salt flats, drainage basins, and many small north-south mountain ranges. The Southwest is predominantly a low-lying desert region. A portion known as the Colorado Plateau, centered around the Four Corners region, is considered to have some of the most spectacular scenery in the world. It is accentuated in such national parks as Grand Canyon, Arches, Mesa Verde National Park and Bryce Canyon, among others. Other smaller Intermontane areas include the Columbia Plateau covering eastern Washington, western Idaho and northeast Oregon and the Snake River Plain in Southern Idaho.
What is the name of the plateau that lies west of the Rocky Mountains?
A:
Intermontane Plateaus
