Question: One big impetus for the development of the AC radio format was that, when rock and roll music first became popular in the mid-1950s, many more conservative radio stations wanted to continue to play current hit songs while shying away from rock. These middle of the road (or "MOR") stations also frequently included older, pre-rock-era adult standards and big band titles to further appeal to adult listeners who had grown up with those songs.
Is there an answer to this question: What does the acronym MOR stand for?

Answer: middle of the road

Question: In 1920, Turkish nationalist forces invaded the fledgling Armenian republic from the east. Turkish forces under the command of Kazm Karabekir captured Armenian territories that Russia had annexed in the aftermath of the 18771878 Russo-Turkish War and occupied the old city of Alexandropol (present-day Gyumri). The violent conflict finally concluded with the Treaty of Alexandropol on 2 December 1920. The treaty forced Armenia to disarm most of its military forces, cede all former Ottoman territory granted to it by the Treaty of Sevres, and to give up all the "Wilsonian Armenia" granted to it at the Sevres treaty. Simultaneously, the Soviet Eleventh Army, under the command of Grigoriy Ordzhonikidze, invaded Armenia at Karavansarai (present-day Ijevan) on 29 November. By 4 December, Ordzhonikidze's forces entered Yerevan and the short-lived Armenian republic collapsed.
Is there an answer to this question: When did the Armenian republic breakdown?

Answer: 4 December

Question: Manufacturers of devices may have their own proprietary numbering system, for example CK722. Since devices are second-sourced, a manufacturer's prefix (like "MPF" in MPF102, which originally would denote a Motorola FET) now is an unreliable indicator of who made the device. Some proprietary naming schemes adopt parts of other naming schemes, for example a PN2222A is a (possibly Fairchild Semiconductor) 2N2222A in a plastic case (but a PN108 is a plastic version of a BC108, not a 2N108, while the PN100 is unrelated to other xx100 devices).
Is there an answer to this question: What is the marking for a 2N2222A in a plastic case?

Answer: PN2222A

Question: Many factors played a role in Britain's long-term economic growth, such as the industrial revolution in the late 1700s and the prominent presence of child labour during the industrial age. Children who worked at an early age were often not forced; but did so because they needed to help their family survive financially. Due to poor employment opportunities for many parents, sending their children to work on farms and in factories was a way to help feed and support the family. Child Labour first started to occur in England when household businesses were turned into local labour markets that mass-produced the once homemade goods. Because children often helped produce the goods out of their homes, working in a factory to make those same goods was a simple change for many of these youths. Although there are many counts of children under the age of ten working for factories, the majority of children workers were between the ages of ten and fourteen. This age range was an important time for many youths as they were first helping to provide for their families; while also transitioning to save for their own future families.
Is there an answer to this question: What was the age of the majority of child workers in Britain?

Answer:
between the ages of ten and fourteen
