The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. The areas of the map where government is spending a great deal of money and is working hard to help discover the answer to these two questions:
1. Can we predict earthquakes
2. Can we control earthquakes
To answer the first question, scientists are looking very closely at the most active fault systems in the country, such as the San Andreas fault in California. A fault is a break between two sections of the earth’s surface. These breaks between sections are the places where earthquakes occur.
Scientists look at the faults for changes which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes accurately and the control of earthquakes is even farther away.
Nevertheless
A. an active fault system
B. a place where earthquakes have been predicted accurately
C. a place where earthquakes have been controlled
D. the location of the Rocky Mountain

Bernard Bailyn has recently reinterpreted the early history of the United States by applying new social research findings on the experiences of European migrants. In his reinterpretation, migration becomes the organizing principle for rewriting the history of pre- industrial North America. His approach rests on four separate propositions.
The first of these asserts that residents of early modern England moved regularly about their countryside: migrating to the New World was simply a "natural spillover’. Although at first the colonies held little positive attraction for the English—they would rather have stayed home—by the eighteenth century people increasingly migrated to America because they regarded it as the land of opportunity. Secondly, Bailyn holds that, contrary to the notion that used to flourish in American history textbooks, there was never a typical New World community. For example, the economic and demographic chara
A. comparing several current interpretations of early American history.
B. providing the theoretical framework that is used by most historians in understanding early American history.
C. refuting an argument about early American history that has been proposed by social historians.
D. discussing a reinterpretation of early American history that is based on new social research on migration.
