It's between A and B. The articles of confederation made the federal government weak and pretty much non-existent in terms of true power. Effectively each state was its own country more or less.
I think A and B sound pretty identical though perhaps choice A isn't the best answer because each state didn't really think about the country as a whole, but rather focused on their own backyard.
<h3>So that's why I'm thinking the final answer is choice B</h3>
Though I would get a second opinion on the matter.
<u>The period in which the greatest economic or technological progress that occurred in the United States was between the end of the 19th century and the first half of the 20th century</u>. <u><em>During this period, the country went from being a simple agricultural economy to the first industrial power in the land</em></u>.
<u>It was in the second half of the nineteenth century when the first manufactures were created with imports of skilled foreign labor from England.</u>
<em><u>The answer is</u></em>: <u>A. Britain supplied a market for American manufactured goods</u>.
