Question

it showed how they can be changed in response to changing circumstances — such critical facts as its political stability, the growth of the economy, and its military readiness. as long as our country was preoccupied with building up these strengths, the monroe doctrine and american foreign policy remained largely the same. but as time went on, the relative strengths of america and the foreign powers underwent a profound change. to begin with, america became the magnet for millions of people who were brave, restless, and hardy enough to hazard the long and dangerous journey to what was seen as the land of endless opportunities. they arrived in staggering numbers. in 1820, the u.s. population was 9.5 million and its average annual increase was 240,000. by 1901, the corresponding totals were 77.6 million and 1.5 million. 10 the immigrants were capable, and they worked hard. by 1895, the u.s. had surpassed great britain in manufacturing output and by 1900, the new world was producing more energy than germany, france, austria - hungary, russia, japan, and italy combined. between the end of the american civil war and the turn of the century, u.s. coal production rose by 800 percent, steel rails by 523 percent, and wheat production guiding questions how did america change following the monroe doctrine? a it became more feared as its population aggressively grew. b it became less respected as it started to extend its influence over other nations. c it became a potential threat to other world powers as its military strengthened. d it became more powerful as production increased from the work of immigrants.

Explanation:

To solve this, we analyze the text. The passage states that by 1900, the US was producing more energy than several nations and had significant production growth (coal, steel rails, wheat) from immigrant labor. Option D says "It became more powerful as production increased from the work of immigrants" which aligns with the text's details about production growth and immigrant contribution. Option A is incorrect (no mention of being feared or aggressive population growth). Option B is incorrect (no info on extending influence less respected). Option C is incorrect (no mention of being a threat or military strengthening other powers).

Answer:

D. It became more powerful as production increased from the work of immigrants.
