PROBLEM: The Neolithic 2 (PPNB) began around 8,800 BCE according to the ASPRO chronology in the Levant (Jericho, Israel). As with the PPNA dates, there are two versions from the same laboratories noted above. This system of terminology, however, is not convenient for southeast Anatolia and settlements of the middle Anatolia basin. This era was before the Mesolithic era.[citation needed] A settlement of 3,000 inhabitants was found in the outskirts of Amman, Jordan. Considered to be one of the largest prehistoric settlements in the Near East, called 'Ain Ghazal, it was continuously inhabited from approximately 7,250 – 5,000 B.

PROBLEM: 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.

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