Problem: Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UTin which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.
When was GMT adopted by the International Astronomical Union?

Starting in 2006, Apple's industrial design shifted to favor aluminum, which was used in the construction of the first MacBook Pro. Glass was added in 2008 with the introduction of the unibody MacBook Pro. These materials are billed as environmentally friendly. The iMac, MacBook Pro, MacBook Air, and Mac Mini lines currently all use aluminum enclosures, and are now made of a single unibody. Chief designer Jonathan Ive continues to guide products towards a minimalist and simple feel, including eliminating of replaceable batteries in notebooks. Multi-touch gestures from the iPhone's interface have been applied to the Mac line in the form of touch pads on notebooks and the Magic Mouse and Magic Trackpad for desktops.
What has Chief Designer Jonathan Ive been able to eliminate in HP notebooks?
A: unanswerable

Context and question: Law offers more ambiguity. Some writings of Plato and Aristotle, the law tables of Hammurabi of Babylon, or even the early parts of the Bible could be seen as legal literature. Roman civil law as codified in the Corpus Juris Civilis during the reign of Justinian I of the Byzantine Empire has a reputation as significant literature. The founding documents of many countries, including Constitutions and Law Codes, can count as literature; however, most legal writings rarely exhibit much literary merit, as they tend to be rather Written by Samuel Dean.
What does Samuel Dean say law offers?
Answer: unanswerable

Question: In 1063, Ferdinand I of Castile divided his realm among his sons, and the Kingdom of Galicia was granted to Garcia II of Galicia. In 1072, it was forcibly annexed by Garcia's brother Alfonso VI of Leon; from that time Galicia was united with the Kingdom of Leon under the same monarchs. In the 13th century Alfonso X of Castile standardized the Castilian language and made it the language of court and government. Nevertheless, in his Kingdom of Galicia the Galician language was the only language spoken, and the most used in government and legal uses, as well as in literature.
Is there an answer to this question: Who standardized Castillan and made it the government's official language?

Answer: Alfonso X

Problem: Molotov%E2%80%93Ribbentrop Pact:

At the beginning of the 1930s, the Nazi Party's rise to power increased tensions between Germany and the Soviet Union along with other countries with ethnic Slavs, who were considered "Untermenschen" (inferior) according to Nazi racial ideology. Moreover, the anti-Semitic Nazis associated ethnic Jews with both communism and financial capitalism, both of which they opposed. Consequently, Nazi theory held that Slavs in the Soviet Union were being ruled by "Jewish Bolshevik" masters. In 1934, Hitler himself had spoken of an inescapable battle against both Pan-Slavism and Neo-Slavism, the victory in which would lead to "permanent mastery of the world", though he stated that they would "walk part of the road with the Russians, if that will help us." The resulting manifestation of German anti-Bolshevism and an increase in Soviet foreign debts caused GermanSoviet trade to dramatically decline.[b] Imports of Soviet goods to Germany fell to 223 million Reichsmarks in 1934 as the more isolationist Stalinist regime asserted power and the abandonment of postWorld War I Treaty of Versailles military controls decreased Germany's reliance on Soviet imports.[clarification needed]

Which political group removed problems between the Soviet and German governments?
