Question: A further limitation of the gramophone record is that fidelity steadily declines as playback progresses; there is more vinyl per second available for fine reproduction of high frequencies at the large-diameter beginning of the groove than exist at the smaller-diameters close to the end of the side. At the start of a groove on an LP there are 510 mm of vinyl per second traveling past the stylus while the ending of the groove gives 200210 mm of vinyl per second less than half the linear resolution. Distortion towards the end of the side is likely to become more apparent as record wear increases.*
Is there an answer to this question: Where can you find only 200-210mm of vinyl?

Answer: ending of the groove

Question: The status of "language" is not solely determined by linguistic criteria, but it is also the result of a historical and political development. Romansh came to be a written language, and therefore it is recognized as a language, even though it is very close to the Lombardic alpine dialects. An opposite example is the case of Chinese, whose variations such as Mandarin and Cantonese are often called dialects and not languages, despite their mutual unintelligibility.
Is there an answer to this question: What types of development help to determine the status of Mandarin?

Answer: unanswerable

Question: Within Shia Islam (Shiism), the various sects came into being because they differed over their Imams' successions, just as the Shia - Sunni separation within Islam itself had come into being from the dispute that had arisen over the succession to Muhammad. Each succession dispute brought forth a different tariqah (literal meaning 'path'; extended meaning 'sect') within Shia Islam. Each Shia tariqah followed its own particular Imam's dynasty, thus resulting in different numbers of Imams for each particular Shia tariqah. When the dynastic line of the separating successor Imam ended with no heir to succeed him, then either he (the last Imam) or his unborn successor was believed to have gone into concealment, that is, The Occultation.
Is there an answer to this question: What great separation came to be from a dispute over the succession to Muhammad?

Answer: Shia - Sunni

Question: The Arsacid Kingdom of Armenia, itself a branch of the Arsacid dynasty of Parthia, was the first state to adopt Christianity as its religion (it had formerly been adherent to Armenian paganism, which was influenced by Zoroastrianism, while later on adopting a few elements regarding identification of its pantheon with Greco-Roman deities). in the early years of the 4th century, likely AD 301, partly in defiance of the Sassanids it seems. In the late Parthian period, Armenia was a predominantly Zoroastrian-adhering land, but by the Christianisation, previously predominant Zoroastrianism and paganism in Armenia gradually declined. Later on, in order to further strengthen Armenian national identity, Mesrop Mashtots invented the Armenian alphabet, in 405 AD. This event ushered the Golden Age of Armenia, during which many foreign books and manuscripts were translated to Armenian by Mesrop's pupils. Armenia lost its sovereignty again in 428 AD to the rivalling Byzantine and Sassanid Persian empires, until the Muslim conquest of Persia overran also the regions in which Armenians lived.
Is there an answer to this question: Why did Armenia make Christianity its official religion?

Answer:
in defiance of the Sassanids
