Stars have been significant features in the design of many United States coins and their number has varied from one to forty-eight stars. Most of the coins issued from about 1799 to the early years of the twentieth century bore thirteen stars representing the thirteen original colonies. Curiously enough, the first American silver coins, issued in 1794, had fifteen stars because by that time Vermont and Kentucky has joined the Union. At that time it was apparently the intention of mint officials to add a star for each new state. Following the admission of Tennessee

in 1796, for example, some varieties of half dimes, dimes, and half-dollars were produced with sixteen starts. As more states were admitted to the Union, however, it quickly became apparent that this scheme would not prove practical and the coins from A798 on were issued with only thirteen stars-one for each ofthe original colonies. Due to an error at the mint, one variety of the A828 half cent was issued with only twelve stars. There is also a variety of the large cent with only A2 stars, but this is the result of a die breakand is not a true error.

The expression “Curiously enough” is used because the author finds it strange that_______

A. Silver coins with fifteen stars appeared before coins with thirteen

B. Vermont and Kentucky joined the Union in 1794

C. Tennessee was the first state to use half dimes

D. No silver coins were issued until 1794.

The goal of Internet-based encyclopedia Wikipedia (www.wikipedia.org) is to give everyone on the planet access to information. Like other encyclopedias, Wikipedia contains lots of information:    more than

2.5 million articles in 200 different languages covering just about every subject. Unlike other encyclopedias, however, Wikipedia is not written by experts, but by ordinary people. These writers are not paid and their names are not published. They contribute to Wikipedia simply because they want to share their knowledge.

Encyclopedias began in ancient times as collections of writings about all aspects of human knowledge. The word itself comes from ancient Greek, and means “a complete general education”. Real popularity for encyclopedias came in the nineteenth century in Europe and the United States, with the publication of encyclopedias written for ordinary readers. With the invention of the CD-ROM, the same amount of information could be put on a few computer discs. Then with the Internet, it became possible to create an online encyclopedia that could be constantly updated, like Microsoft’s Encarta. However, even Internet-based encyclopedias like Encarta were written by paid experts. At first, Wikipedia, the brainchild of Jimmy Wales, a businessman in Chicago, was not so different from these. In 2001, he had the idea for an Internet-based encyclopedia that would provide information quickly and easily to everyone. Furthermore, that information would be available free, unlike other Internet encyclopedias at that time.

But Wales, like everyone else, believed that people with special knowledge were needed to write the articles, and so he began by hiring experts. He soon changed his approach, however, as it took them a long time to finish their work. He decided to open up the encyclopedia in a radical new way, so that everyone would have access not only to the information, but also to the process of putting this information online. To do this, he used what is known as “Wiki” software (from the Hawaiian word for “fast”), which allows users to create or alter content on web page. The system is very simple: When you open the web site, you can simply search for information or you can log on to become a writer or editor of articles. If you find an article that interests you – about your hometown, for example – you can correct it or expand it. This  process goes on until no one is interested in making any more changes.
