Problem: For much of Eton's history, junior boys had to act as "fags", or servants, to older boys. Their duties included cleaning, cooking, and running errands. A Library member was entitled to yell at any time and without notice, "Boy, Up!" or "Boy, Queue!", and all first-year boys had to come running. The last boy to arrive was given the task. These practices, known as fagging, were partially phased out of most houses in the 1970s. Captains of House and Games still sometimes give tasks to first-year boys, such as collecting the mail from School Office.[citation needed]
What were common duties of younger servant students?

Problem: If the data to be compressed is analog (such as a voltage that varies with time), quantization is employed to digitize it into numbers (normally integers). This is referred to as analog-to-digital (A/D) conversion. If the integers generated by quantization are 8 bits each, then the entire range of the analog signal is divided into 256 intervals and all the signal values within an interval are quantized to the same number. If 16-bit integers are generated, then the range of the analog signal is divided into 65,536 intervals.
What does "A/D" stand for?

Answer: analog-to-digital


Problem: From the 2011 Census, the Office for National Statistics published that Plymouth's unitary authority area population was 256,384; 15,664 more people than that of the last census from 2001, which indicated that Plymouth had a population of 240,720. The Plymouth urban area had a population of 260,203 in 2011 (the urban sprawl which extends outside the authority's boundaries). The city's average household size was 2.3 persons. At the time of the 2011 UK census, the ethnic composition of Plymouth's population was 96.2% White (of 92.9% was White British), with the largest minority ethnic group being Chinese at 0.5%. The white Irish ethnic group saw the largest decline in its share of the population since the 2001 Census (-24%), while the Other Asian and Black African had the largest increases (360% and 351% respectively). This excludes the two new ethnic groups added to the 2011 census of Gypsy or Irish Traveller and Arab. The population rose rapidly during the second half of the 19th century, but declined by over 1.6% from 1931 to 1951.
