Spanish is currently the most widely taught non-English language in American secondary schools and of higher education. More than 1.4 million university students were enrolled in language courses in autumn of 2002 and Spanish is the most widely taught language in American colleges and universities with 53 percent of the total number of people enrolled, followed by French (14.4%), German (7.1%), Italian (4.5%), American Sign language (4.3%), Japanese (3.7%), and Chinese (2.4%) although the totals remain relatively small in relation to the total U.S population.
Are these other languages learned in the U.S. as popular as Spanish?
A: totals remain relatively small in relation to the total U.S population.

There is ongoing debate about whether central banks should target zero inflation (which would mean a constant value for the U.S. dollar over time) or low, stable inflation (which would mean a continuously but slowly declining value of the dollar over time, as is the case now). Although some economists are in favor of a zero inflation policy and therefore a constant value for the U.S. dollar, others contend that such a policy limits the ability of the central bank to control interest rates and stimulate the economy when needed.
What would zero inflation mean for control interest over time?
A: unanswerable

Greenware ceramics made from celadon had been made in the area since the 3rd-century Jin dynasty, but it returned to prominence—particularly in Longquan—during the Southern Song and Yuan. Longquan greenware is characterized by a thick unctuous glaze of a particular bluish-green tint over an otherwise undecorated light-grey porcellaneous body that is delicately potted. Yuan Longquan celadons feature a thinner, greener glaze on increasingly large vessels with decoration and shapes derived from Middle Eastern ceramic and metalwares. These were produced in large quantities for the Chinese export trade to Southeast Asia, the Middle East, and (during the Ming) Europe. By the Ming, however, production was notably deficient in quality. It is in this period that the Longquan kilns declined, to be eventually replaced in popularity and ceramic production by the kilns of Jingdezhen in Jiangxi.
 What decorations are Yuan Longquan non-celadons derived from?
A: unanswerable

Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Larger capacitors like electrolytics usually display the actual capacitance together with the unit (for example, 220 μF). Smaller capacitors like ceramics, however, use a shorthand consisting of three numeric digits and a letter, where the digits indicate the capacitance in pF (calculated as XY × 10Z for digits XYZ) and the letter indicates the tolerance (J, K or M for ±5%, ±10% and ±20% respectively).
What does the abbreviated electrical characteristics of larger capacitors consist of?
A:
unanswerable
