问题     In the 18th century New York was smaller than Philadelphia and Boston. Today it is the largest city in America. How can the change in its size and importance be explained?
    To answer this question we must consider certain facts about geography, history and economics. Together these three will explain the huge growth of America’s most famous city.
    The map of the Northeast shows that four of the most heavily populated areas in this region are around seaports. At these points materials from across the sea enter the United States, and the product of the land are sent there for export across the sea.
    Economists know that places where transportation lines meet are good places for making raw materials into finished goods. That is why seaports often have cities nearby. But cities like New York needed more than their geographical location in order to become great industrial centers. Their development did not happen simply by chance. [br] What can be found on the map about the Northeast area?

选项 A、Four cities with a large population are around the seaports.
B、Four cities burdened with industries are around the seaports.
C、Four of the most polluted cities are around the seaports.
D、Most heavily populated areas in the region are around seaports.

答案 A

解析 事实细节题。由线索词map,Northeast定位到第三段第一句。文中说,看东北部地区的地图可以发现,这一带人口最多的四个地区都在海港附近,A)表述的内容与此相符。
