Problem: Chickens are medium-sized, chunky birds with an upright stance and characterised by fleshy red combs and wattles on their heads. Males, known as cocks, are usually larger, more boldly coloured, and have more exaggerated plumage than females (hens). Chickens are gregarious, omnivorous, ground-dwelling birds that in their natural surroundings search among the leaf litter for seeds, invertebrates, and other small animals. They seldom fly except as a result of perceived danger, preferring to run into the undergrowth if approached. Today's domestic chicken (Gallus gallus domesticus) is mainly descended from the wild red junglefowl of Asia, with some additional input from grey junglefowl. Domestication is believed to have taken place between 7,000 and 10,000 years ago, and what are thought to be fossilized chicken bones have been found in northeastern China dated to around 5,400 BC. Archaeologists believe domestication was originally for the purpose of cockfighting, the male bird being a doughty fighter. By 4,000 years ago, chickens seem to have reached the Indus Valley and 250 years later, they arrived in Egypt. They were still used for fighting and were regarded as symbols of fertility. The Romans used them in divination, and the Egyptians made a breakthrough when they learned the difficult technique of artificial incubation. Since then, the keeping of chickens has spread around the world for the production of food with the domestic fowl being a valuable source of both eggs and meat.

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: Soteriologically, most Methodists are Arminian, emphasizing that Christ accomplished salvation for every human being, and that humans must exercise an act of the will to receive it (as opposed to the traditional Calvinist doctrine of monergism). Methodism is traditionally low church in liturgy, although this varies greatly between individual congregations; the Wesleys themselves greatly valued the Anglican liturgy and tradition. Methodism is known for its rich musical tradition; John Wesley's brother, Charles, was instrumental in writing much of the hymnody of the Methodist Church, and many other eminent hymn writers come from the Methodist tradition.
Who wrote most of the Methodist hymns?

Answer:
John Wesley's brother, Charles
