Nashville's 13-county metropolitan area has been the state's largest since c. 1990. Chattanooga and Knoxville, both in the eastern part of the state near the Great Smoky Mountains, each has approximately one-third of the population of Memphis or Nashville. The city of Clarksville is a fifth significant population center, some 45 miles (72 km) northwest of Nashville. Murfreesboro is the sixth-largest city in Tennessee, consisting of some 108,755 residents.

QUES: A TiVo service update in July 2008 allowed the system to search and play YouTube videos. In January 2009, YouTube launched "YouTube for TV", a version of the website tailored for set-top boxes and other TV-based media devices with web browsers, initially allowing its videos to be viewed on the PlayStation 3 and Wii video game consoles. In June 2009, YouTube XL was introduced, which has a simplified interface designed for viewing on a standard television screen. YouTube is also available as an app on Xbox Live. On November 15, 2012, Google launched an official app for the Wii, allowing users to watch YouTube videos from the Wii channel. An app is also available for Wii U and Nintendo 3DS, and videos can be viewed on the Wii U Internet Browser using HTML5. Google made YouTube available on the Roku player on December 17, 2013 and in October 2014, the Sony PlayStation 4.

QUES: By the time of the Uruk period (c. 41002900 BC calibrated), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers. It is fairly certain that it was during the Uruk period that Sumerian cities began to make use of slave labor captured from the hill country, and there is ample evidence for captured slaves as workers in the earliest texts. Artifacts, and even colonies of this Uruk civilization have been found over a wide areafrom the Taurus Mountains in Turkey, to the Mediterranean Sea in the west, and as far east as central Iran.
During which period did Sumerian cities begin using slave labor?

ANS: Uruk

Some of the earliest recorded observations ever made through a telescope, Galileo's drawings on 28 December 1612 and 27 January 1613, contain plotted points that match up with what is now known to be the position of Neptune. On both occasions, Galileo seems to have mistaken Neptune for a fixed star when it appeared closein conjunctionto Jupiter in the night sky; hence, he is not credited with Neptune's discovery. At his first observation in December 1612, Neptune was almost stationary in the sky because it had just turned retrograde that day. This apparent backward motion is created when Earth's orbit takes it past an outer planet. Because Neptune was only beginning its yearly retrograde cycle, the motion of the planet was far too slight to be detected with Galileo's small telescope. In July 2009, University of Melbourne physicist David Jamieson announced new evidence suggesting that Galileo was at least aware that the 'star' he had observed had moved relative to the fixed stars.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who drew Neptune after observing it with a telescope?
Ah, so.. Galileo

Context and question: The Boston Globe wrote that "if there's one school that can lay claim to educating the nation's top national leaders over the past three decades, it's Yale." Yale alumni were represented on the Democratic or Republican ticket in every U.S. Presidential election between 1972 and 2004. Yale-educated Presidents since the end of the Vietnam War include Gerald Ford, George H.W. Bush, Bill Clinton, and George W. Bush, and major-party nominees during this period include John Kerry (2004), Joseph Lieberman (Vice President, 2000), and Sargent Shriver (Vice President, 1972). Other Yale alumni who made serious bids for the Presidency during this period include Hillary Clinton (2008), Howard Dean (2004), Gary Hart (1984 and 1988), Paul Tsongas (1992), Pat Robertson (1988) and Jerry Brown (1976, 1980, 1992).
