The house which forms the architectural core of the palace was built for the first Duke of Buckingham and Normanby in 1703 to the design of William Winde. The style chosen was of a large, three-floored central block with two smaller flanking service wings. Buckingham House was eventually sold by Buckingham's descendant, Sir Charles Sheffield, in 1761 to George III for 21,000. Sheffield's leasehold on the mulberry garden site, the freehold of which was still owned by the royal family, was due to expire in 1774.

The Muslim minority in Thrace, which amounts to approximately 0.95% of the total population, consists of speakers of Turkish, Bulgarian (Pomaks) and Romani. Romani is also spoken by Christian Roma in other parts of the country. Further minority languages have traditionally been spoken by regional population groups in various parts of the country. Their use has decreased radically in the course of the 20th century through assimilation with the Greek-speaking majority. Today they are only maintained by the older generations and are on the verge of extinction. This goes for the Arvanites, an Albanian-speaking group mostly located in the rural areas around the capital Athens, and for the Aromanians and Moglenites, also known as Vlachs, whose language is closely related to Romanian and who used to live scattered across several areas of mountainous central Greece. Members of these groups ethnically identify as Greeks and are today all at least bilingual in Greek.
What groups are called Vlachs?
A: Aromanians and Moglenites

Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.
What is the definition of atmospheric pressure?
A: unanswerable

Air defence in naval tactics, especially within a carrier group, is often built around a system of concentric layers with the aircraft carrier at the centre. The outer layer will usually be provided by the carrier's aircraft, specifically its AEW&C aircraft combined with the CAP. If an attacker is able to penetrate this layer, then the next layers would come from the surface-to-air missiles carried by the carrier's escorts; the area-defence missiles, such as the RIM-67 Standard, with a range of up to 100 nmi, and the point-defence missiles, like the RIM-162 ESSM, with a range of up to 30 nmi. Finally, virtually every modern warship will be fitted with small-calibre guns, including a CIWS, which is usually a radar-controlled Gatling gun of between 20mm and 30mm calibre capable of firing several thousand rounds per minute.
The next layer's surface-to-air missiles are carried by what?
A:
the carrier's escorts
