问题    The agriculture revolution in the nineteenth century involved two things: the invention of labor-saving machinery and the development of scientific agriculture. Labor-saving naturally appeared first where labor was rare. "In Europe", said Thomas Jefferson, " the object is to make the most of their land, labor being sufficient: here it is to make the most of our labor, land being abundant. " It was in America, therefore, that the great advances in nineteenth-century agricultural machinery first came.
   At the opening of the century, with the exception of a crude(粗糙的)plow, farmers could have carried practically all of the existing agricultural tools on their backs. By 1860, most of the machinery in use today had been designed in an early form. The most important of the early inventions was the iron plow. As early as 1890 Charles Newbolt of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in introducing his invention. The farmers, however, would bring home none of it, claiming that the iron poisoned the soil and made the weeds grow. Nevertheless, many people devoted their attention to the plow, until in 1869, James Oliver of South Bend, Indiana, turned out the first chilled steel plow.  
The word "here" refers to______.
选项 A、Europe
B、America
C、New Jersey
D、Indiana
答案B
解析 语义词义题。Thomas Jefferson是美国的第三任总统，前面说的是欧洲的情况，而他自己所指的here就是他自己的国家——美国。
