In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought its western border within reach of the Pacific Ocean.

(A) In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought

(B) For about four cents an acre the United States acquired, in the Louisiana Purchase of 1803, 828,000 square miles, more than doubling the country's size and it brought

(C) With the Louisiana Purchase in 1803, the United States acquired 828,000 square miles for about four cents an acre, more than doubling its size and bringing

(D) The United States, in the Louisiana Purchase of 1803, for about four cents an acre, acquired 828,000 square miles, more than doubling the country's size, bringing

(E) Acquiring 828,000 square miles in the Louisiana Purchase of 1803, the United States bought it for about four cents an acre, more than doubling the country's size and bringing

答案是C选项

想问一下，未画线部分的its 和C选项中的 its 指代是同一个对象吗，是什么呢？

我的理解是，划线部分的its指的是 Louisiana  这个州（D选项将its改为了 the country's ）， 而未画线部分的 its指的是United States （应该意思是说的是将美国的边界延伸到了太平洋），这样指代就不一致了。。。

请牛牛们帮忙翻译一下

Louisiana Purchase of 1803是一个整体,意思是1803年发生的路易斯安那采购行动

两个it都是指the United States

呵呵 谢LS。。。
