Problem: Tibet:

The atmosphere is severely dry nine months of the year, and average annual snowfall is only 18 inches (46 cm), due to the rain shadow effect. Western passes receive small amounts of fresh snow each year but remain traversible all year round. Low temperatures are prevalent throughout these western regions, where bleak desolation is unrelieved by any vegetation bigger than a low bush, and where wind sweeps unchecked across vast expanses of arid plain. The Indian monsoon exerts some influence on eastern Tibet. Northern Tibet is subject to high temperatures in the summer and intense cold in the winter.

What influences the weather in northern Tibet?

Problem: The first phase of neoclassicism in France is expressed in the "Louis XVI style" of architects like Ange-Jacques Gabriel (Petit Trianon, 1762–68); the second phase, in the styles called Directoire and "Empire", might be characterized by Jean Chalgrin's severe astylar Arc de Triomphe (designed in 1806). In England the two phases might be characterized first by the structures of Robert Adam, the second by those of Sir John Soane. The interior style in France was initially a Parisian style, the "Goût grec" ("Greek style") not a court style. Only when the young king acceded to the throne in 1771 did Marie Antoinette, his fashion-loving Queen, bring the "Louis XVI" style to court.
Who styled the court in France for more modern design after 1771?

Answer: Marie Antoinette

Translation of sung texts is generally much more restrictive than translation of poetry, because in the former there is little or no freedom to choose between a versified translation and a translation that dispenses with verse structure. One might modify or omit rhyme in a singing translation, but the assignment of syllables to specific notes in the original musical setting places great challenges on the translator. There is the option in prose sung texts, less so in verse, of adding or deleting a syllable here and there by subdividing or combining notes, respectively, but even with prose the process is almost like strict verse translation because of the need to stick as closely as possible to the original prosody of the sung melodic line.
Why is the translation of sung texts more restrictive?
A: little or no freedom to choose between a versified translation


Context and question: Alsace is one of the most conservative régions of France. It is one of just two régions in metropolitan France where the conservative right won the 2004 région elections and thus controls the Alsace Regional Council. Conservative leader Nicolas Sarkozy got his best score in Alsace (over 65%) in the second round of the French presidential elections of 2007. The president of the Regional Council is Philippe Richert, a member of the Union for a Popular Movement, elected in the 2010 regional election. The frequently changing status of the région throughout history has left its mark on modern day politics in terms of a particular interest in national identity issues. Alsace is also one of the most pro-EU regions of France. It was one of the few French regions that voted 'yes' to the European Constitution in 2005.
What constitution was voted on in 2010?
Answer: unanswerable


Question: The shape and size of the brain varies greatly in different species, and identifying common features is often difficult. Nevertheless, there are a number of principles of brain architecture that apply across a wide range of species. Some aspects of brain structure are common to almost the entire range of animal species; others distinguish "advanced" brains from more primitive ones, or distinguish vertebrates from invertebrates.
Is there an answer to this question: Animals without a spine are called what?

Answer: invertebrates

At no more than 200 kilometres (120 mi) north to south and 130 kilometres (81 mi) east to west, Swaziland is one of the smallest countries in Africa. Despite its size, however, its climate and topography is diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is primarily ethnic Swazis whose language is siSwati. They established their kingdom in the mid-18th century under the leadership of Ngwane III; the present boundaries were drawn up in 1881. After the Anglo-Boer War, Swaziland was a British protectorate from 1903 until 1967. It regained its independence on 6 September 1968.
When did the ethnic Swazis establish a kingdom?
A:
mid-18th century
