Problem: Given the question: Extract the answer to the question from the following context. Question: Other than a 7 degree span north and south of the equator, which latitudes have glaciers? Context: The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. Glaciers can be found in all latitudes except from 20 to 27 north and south of the equator where the presence of the descending limb of the Hadley circulation lowers precipitation so much that with high insolation snow lines reach above 6,500 m (21,330 ft). Between 19N and 19S, however, precipitation is higher and the mountains above 5,000 m (16,400 ft) usually have permanent snow.

Problem: Given the question: Extract the answer to the question from the following context. Question: What does the A stand for in ASCII? Context: ASCII (i/ski/ ASS-kee), abbreviated from American Standard Code for Information Interchange, is a character-encoding scheme (the IANA prefers the name US-ASCII). ASCII codes represent text in computers, communications equipment, and other devices that use text. Most modern character-encoding schemes are based on ASCII, though they support many additional characters. ASCII was the most common character encoding on the World Wide Web until December 2007, when it was surpassed by UTF-8, which is fully backward compatibe to ASCII.
