Problem: Translation of a text that is sung in vocal music for the purpose of singing in another languagesometimes called "singing translation"is closely linked to translation of poetry because most vocal music, at least in the Western tradition, is set to verse, especially verse in regular patterns with rhyme. (Since the late 19th century, musical setting of prose and free verse has also been practiced in some art music, though popular music tends to remain conservative in its retention of stanzaic forms with or without refrains.) A rudimentary example of translating poetry for singing is church hymns, such as the German chorales translated into English by Catherine Winkworth.
What is most vocal music set to in Western tradition?
The answer is the following: verse

Problem: Nociceptive pain is caused by stimulation of peripheral nerve fibers that respond to stimuli approaching or exceeding harmful intensity (nociceptors), and may be classified according to the mode of noxious stimulation. The most common categories are "thermal" (e.g. heat or cold), "mechanical" (e.g. crushing, tearing, shearing, etc.) and "chemical" (e.g. iodine in a cut or chemicals released during inflammation). Some nociceptors respond to more than one of these modalities and are consequently designated polymodal.
How is nociceptive pain classified?
The answer is the following: according to the mode of noxious stimulation

Problem: The earliest archaeological artifacts in Iran, like those excavated at the Kashafrud and Ganj Par sites, attest to a human presence in Iran since the Lower Paleolithic era, c. 800,000200,000 BC. Iran's Neanderthal artifacts from the Middle Paleolithic period, c. 200,00040,000 BC, have been found mainly in the Zagros region, at sites such as Warwasi and Yafteh Cave.[page needed] Around 10th to 8th millennium BC, early agricultural communities such as Chogha Golan and Chogha Bonut began to flourish in Iran, as well as Susa and Chogha Mish developing in and around the Zagros region.[page needed]
How long ago were the earliest artifacts from that were evidence of humans in Iran?
The answer is the following: the Lower Paleolithic era, c. 800,000200,000 BC

Problem: The Scheinergrade (Sch.) system was devised by the German astronomer Julius Scheiner (18581913) in 1894 originally as a method of comparing the speeds of plates used for astronomical photography. Scheiner's system rated the speed of a plate by the least exposure to produce a visible darkening upon development. Speed was expressed in degrees Scheiner, originally ranging from 1 Sch. to 20 Sch., where an increment of 19 Sch. corresponded to a hundredfold increase in sensitivity, which meant that an increment of 3 Sch. came close to a doubling of sensitivity.
What do degrees Scheiner indicate?
The answer is the following:
the speed of a plate
