The origin of the almighty dollar is in what is now the Czech Republic. In 1519 ,a silver mine near the town of Joachimstal literally "Joachim’s valley," from the German Tal, meaning valley began minting a silver coin called, unimaginatively, the Joachimstaler. The coin, which was circulated widely, became better known by its clipped form, the taler. In Dutch and Low German, the initial consonant softened to become daler. English adopted this form, eventually changing its spelling to the modern dollar. In the American colonies, there was no standard currency. The coin that was in widest use was the Spanish Peso, known also as" Pieces of Eight" because it could be divided into eight pie-like pieces. The English colonists informally assigned the name dollar to this coin. In 1785, when the Continental Congress established U.S. currency ,they adopted dollar as name for the standard unit of currency ,at the suggestion of Governeur Morris and Thomas Jefferson ,.because the term was widely known and was not associated with any form of official English currency. Jefferson also coined the term disme, from the French dixieme, for a tenth of a dollar. Pronounced deem, it eventually became dime. The origin of the sign has several folkloric stories attached. One says that Thomas Jefferson invented it, perhaps as a sort of monogram for TS. Jefferson was the first to use the symbol in relation to the U.S. dollar, but this story is fanciful. Another says that originally it was U superimposed over an S,for U.S. of course. Eventually the base of the U eroded due to poor printing technology, leaving an S with two lines through it. Another says that it is a variant of a figure eight that appeared on the Spanish Peso, standing for the pieces of eight. This Past is close to the truth, but not quite there. The Spanish royal family used on its escutcheon, two pillars representing the Pillars of Hercules in Gibraltar and Morocco crossed by an unfurled banner reading" Plus Ultra." This symbol appeared on the Peso, and looked much like the modern sign. It was adopted as a symbol for the Peso in the American colonies, and was transferred to the dollar. The U.S. was the first nation to adopt an official currency named the dollar. In 1797 ,the Bank of England began minting" dollar" coins as bank-issued currency. Other nations that have adopted the name dollar for their currency have done so in emulation of either the U.S. or this short-lived Bank of England practice.Which one of the following is still in question () A. Thomas Jefferson invented sign for US dollars.B. The origin of the dollar is in the Czech Republic.C. Spanish Peso was used widely in old American colonies.D. The British central bank has once issued coins named dollars.

One U.S. state senator proposed that high school students be allowed to study either foreign language or computer coding.[A] As computer coding has become an increasingly sought-after skill, more K-12 schools are working it into their curriculums. Some states have considered allowing students to forgo (放弃) foreign language for coding classes, despite opposition from educators.[B] There’s a debate over whether it’s appropriate to teach coding in elementary schools, with fierce opinions on each side. When it comes to allowing coding to fill foreign language requirements, though, most educators agree: Coding should be added to curriculums, but not at the expense of foreign language classes.[C] The idea is that computer programming is a language, allowing people to communicate with machines and programs. It’s the language of the 21st century and more valuable than a natural language, some advocates argue. The computer science field is growing faster than schools can keep up because of budget constraints and a lack of skills training for teachers.[D] According to the 2016 U.S. News/Raytheon STEM Index, computer science jobs have helped boost wages in the U.S., and computer-related jobs hold the top seven positions in STEM fields for highest number of workers. Foreign language interest, on the other hand, is declining for the first time since 1995. The number of higher education language enrollments declined between 2009 and 2013 by more than 111,000 spots, according to the Modern Language Association of America.[E] “I think the opportunity to give people a choice is important,” says Florida state Senator Jeremy Ring, who introduced a bill last year that would allow Florida students to choose between foreign language and coding classes for the purpose of university admissions requirements. “I think if you’re going to give two years of language in high school, you might as well do computer coding.”请选择和题干内容相一致的段落。A、[A]B、[B]C、[C]D、[D]E、[E]

On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the "wisdom of crowds" effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate. This effect capitalizes on the fact that when people make errors, those errors aren't always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won't cancel each other out. In more technical terms, the wisdom of crowds requires that people's estimates be independent. If, for whatever reasons, people's errors become correlated or dependent, the accuracy of the estimate will go down. But a new study led by Joaquin Navajas offered an interesting twist(转折)on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals. In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn't the dominant response. Most frequently, the groups reported that they "shared arguments and reasoned together." Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous. What is paragraph 2 of the text mainly about? A. The methods of estimation.B. The underlying logic of the effect.C. The causes of people's errors.D. The design of Galton's experiment.
