[单项选择]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 character of early New England towns varied considerably.

A. many migrants to colonial North America were nor successful financially.
B. New England communities were much alike in terms of their economics and demographics.
C. many migrants to colonial North America failed to maintain ties with their European relations.
D. the level of literacy in New England communities was very high.
