QUES: Following the breakup of the Russian Empire in the aftermath of World War I for a brief period, from 1918 to 1920, Armenia was an independent republic. In late 1920, the communists came to power following an invasion of Armenia by the Red Army, and in 1922, Armenia became part of the Transcaucasian SFSR of the Soviet Union, later forming the Armenian Soviet Socialist Republic (1936 to September 21, 1991). In 1991, Armenia declared independence from the USSR and established the second Republic of Armenia.
When did Armenia leave the USSR?

ANS: 1991

QUES: Agriculture accounted for less than 20% of both net material product and total employment before the dissolution of the Soviet Union in 1991. After independence, the importance of agriculture in the economy increased markedly, its share at the end of the 1990s rising to more than 30% of GDP and more than 40% of total employment. This increase in the importance of agriculture was attributable to food security needs of the population in the face of uncertainty during the first phases of transition and the collapse of the non-agricultural sectors of the economy in the early 1990s. As the economic situation stabilized and growth resumed, the share of agriculture in GDP dropped to slightly over 20% (2006 data), although the share of agriculture in employment remained more than 40%.
Why did agriculture become so significant for Armenia's economy?

ANS: food security needs

QUES: DVB created first the standard for DVB-S digital satellite TV, DVB-C digital cable TV and DVB-T digital terrestrial TV. These broadcasting systems can be used for both SDTV and HDTV. In the US the Grand Alliance proposed ATSC as the new standard for SDTV and HDTV. Both ATSC and DVB were based on the MPEG-2 standard, although DVB systems may also be used to transmit video using the newer and more efficient H.264/MPEG-4 AVC compression standards. Common for all DVB standards is the use of highly efficient modulation techniques for further reducing bandwidth, and foremost for reducing receiver-hardware and antenna requirements.
What did the Grand Alliance propose as the new standard for SDTV and HDTV?

ANS: ATSC

QUES: The first known European explorer to reach Bermuda was Spanish sea captain Juan de Bermúdez in 1503, after whom the islands are named. He claimed the apparently uninhabited islands for the Spanish Empire. Paying two visits to the archipelago, Bermúdez never landed on the islands, but did create a recognisable map of the archipelago. Shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription in Portuguese Rock (previously called Spanish Rock). Subsequent Spanish or other European parties are believed to have released pigs there, which had become feral and abundant on the island by the time European settlement began. In 1609, the English Virginia Company, which had established Jamestown in Virginia (a term originally applied to all of the North American continent) two years earlier, permanently settled Bermuda in the aftermath of a hurricane, when the crew and passengers of the Sea Venture steered the ship onto the surrounding reef to prevent its sinking, then landed ashore.
What is the name of the first European explorer to reach Bermuda?

Juan de Bermúdez
