Question

immigration and neutrality
immigration to the united states (1840-1920)
immigration to the united states peaked around 1910.
between 1910 and 1920, immigration declined.
this was most likely due to dropdown options: the war in europe, a lack of jobs, industrialization.
chart: number of new immigrants (y-axis) vs. year (x-axis: 1840-1920) with data points showing trend, peak at 1910, decline by 1920

Explanation:

To determine the reason for the decline in US immigration between 1910 - 1920, we analyze the context:

• "A lack of jobs": Industrialization was growing in the US during this period, creating jobs, so this is incorrect.
• "Industrialization": Industrialization would likely attract immigrants (more jobs), not cause a decline, so this is incorrect.
• "The war in Europe": World War I (1914 - 1918) occurred during this time. The war disrupted European societies, making it harder for people to emigrate, and also the US had concerns related to the war (e.g., anti - immigrant sentiment due to war - related tensions, and the war's impact on European economies/societies that drove emigration). This aligns with the decline in immigration.

Answer:

the war in Europe
