| Community cancer clusters are viewed
quite differently by citizen activists than by epidemiologists.
Environmentalists and concerned local residents, for instance, might immediately
suspect environmental radiation as the culprit when a high incidence of cancer
cases occurs near a nuclear facility. Epidemiologists, in contrast, would be
more likely to say that the incidences were "inconclusive" or the result of pure
chance. And when a breast cancer survivor, Lorraine Pace, mapped 20 breast
cancer cases occurring in her West Islip, Long Island, community, her
rudimentary research efforts were guided more by hope--that a specific
environmental agent could be correlated with the cancers than by scientific
method.

The Cherokee Nation Long before the white man came to America, the land belonged to the American Indian nations. The nation of the Cherokees lived in what is now the southeastern part of the United States. After the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing were to the white man. He decided to invent a way to write down the spoken Cherokee language. He began by making word pictures. For each word he drew a picture. But that proved impossible-there were just too many words. Then he took the 85 sounds that made up the language. Using his own imagination and an English spelling book, Sequoyah invented a sign for each sound. His alphabet proved amazingly easy to learn. Before long, many Cherokees knew how to read and write in their own language. By 1828, they were even printing their own newspaper. In 1830, the U.S. Congress passed a law. It allowed the A. in carts. B. on horseback. C. on foot. D. all of the above. [判断题]临时性信息网络，经销商客户经理负责开发服务维修网点、配件供应网点、运输公司等。
