The massive magnitude(震级) 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.

These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.

Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.

The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic(地震的) stresses which encircles(环绕,包围) the Pacific Ocean. All along this line, the plates on which the continents move press against each other.

Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal(地壳的)movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.

Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.

“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.

为了研究吸烟和户外工作(日晒)对唇癌发生的影响,对50~69岁唇癌病人和作为对照的皮肤癌病人进行比较,结果如下表所示:

选择皮肤癌病人为对照组合适,可以反映该群体中暴露发生的情况。该推论是()。

A.正确的

B.不正确,因为皮肤癌在户外工作人员中比户内工作人员更为常见,因此对照组不能反映该群体中暴露发生的情况

C.不正确,因为进行比较的两个群体必须来自同一种疾病
