Question: The phonograph disc record was the primary medium used for music reproduction until late in the 20th century, replacing the phonograph cylinder record–with which it had co-existed from the late 1880s through to the 1920s–by the late 1920s. Records retained the largest market share even when new formats such as compact cassette were mass-marketed. By the late 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the vinyl record left the mainstream in 1991. From the 1990s to the 2010s, records continued to be manufactured and sold on a much smaller scale, and were especially used by disc jockeys (DJ)s, released by artists in some genres, and listened to by a niche market of audiophiles. The phonograph record has made a niche resurgence in the early 21st century – 9.2 million records were sold in the U.S. in 2014, a 260% increase since 2009. Likewise, in the UK sales have increased five-fold from 2009 to 2014.

Answer: What was the primary use of a phonographic disc record?


Question: As soon as the Greek War of Independence broke out in 1821, several Greek Cypriots left for Greece to join the Greek forces. In response, the Ottoman governor of Cyprus arrested and executed 486 prominent Greek Cypriots, including the Archbishop of Cyprus, Kyprianos and four other bishops. In 1828, modern Greece's first president Ioannis Kapodistrias called for union of Cyprus with Greece, and numerous minor uprisings took place. Reaction to Ottoman misrule led to uprisings by both Greek and Turkish Cypriots, although none were successful. After centuries of neglect by the Turks, the unrelenting poverty of most of the people, and the ever-present tax collectors fuelled Greek nationalism, and by the 20th century idea of enosis, or union, with newly independent Greece was firmly rooted among Greek Cypriots.

Answer: What year did the Greek war of independence break out?


Question: In 1997, OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the Federal Government. The development of the data standards stem in large measure from new responsibilities to enforce civil rights laws." Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group. Prior to this decision, the Census and other government data collections asked people to report only one race.

Answer:
Who decided on the standards for the classification of race and ethnicity and federal data?
