It was temporarily under the control of the Tibetan empire and Chinese from 650–680 and then under the control of the Umayyads in 710. The Samanid Empire, 819 to 999, restored Persian control of the region and enlarged the cities of Samarkand and Bukhara (both cities are today part of Uzbekistan) which became the cultural centers of Iran and the region was known as Khorasan. The Kara-Khanid Khanate conquered Transoxania (which corresponds approximately with modern-day Uzbekistan, Tajikistan, southern Kyrgyzstan and southwest Kazakhstan) and ruled between 999–1211. Their arrival in Transoxania signaled a definitive shift from Iranian to Turkic predominance in Central Asia, but gradually the Kara-khanids became assimilated into the Perso-Arab Muslim culture of the region.
Who shrunk the cities of Samarkand and Bukhara?

The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base, the matrix, or the solvent. The secondary constituents are often called solutes. If there is a mixture of only two types of atoms, not counting impurities, such as a copper-nickel alloy, then it is called a binary alloy. If there are three types of atoms forming the mixture, such as iron, nickel and chromium, then it is called a ternary alloy. An alloy with four constituents is a quaternary alloy, while a five-part alloy is termed a quinary alloy. Because the percentage of each constituent can be varied, with any mixture the entire range of possible variations is called a system. In this respect, all of the various forms of an alloy containing only two constituents, like iron and carbon, is called a binary system, while all of the alloy combinations possible with a ternary alloy, such as alloys of iron, carbon and chromium, is called a ternary system.
An alloy with five what is called a quaternary alloy?
A: unanswerable

Public buildings generally varied between the extremes of plain boxes with grid windows and Italian Late Renaissance palaces, depending on budget. Somerset House in London, designed by Sir William Chambers in 1776 for government offices, was as magnificent as any country house, though never quite finished, as funds ran out. Barracks and other less prestigious buildings could be as functional as the mills and factories that were growing increasingly large by the end of the period. But as the period came to an end many commercial projects were becoming sufficiently large, and well-funded, to become "architectural in intention", rather than having their design left to the lesser class of "surveyors".
In what year was Somerset House designed?
A: 1776
