What does a study of immigration figures before 1921 indicate?

Question

Quizplus · Accepted Answer

A study of immigration figures before 1921 indicates that the diversification of immigrants increased since the colonial period of U.S. history. This is supported by the fact that while a significant number of immigrants came from the British Isles, immigration from other parts of Europe and Asia also increased during this period, contributing to a more diverse population.

Answer: B 
 While immigration did slow down as the 1921 quota act approached, this is not necessarily reflective of immigration patterns before 1921. Therefore, option B is not the best choice as it only addresses a specific period of time.

Answer: A and D 
 There is some evidence to suggest that an overwhelming majority of immigrants came from the British Isles before 1921, however, this does not necessarily indicate a clear link between immigration patterns and growth in the U.S. economy. Therefore, option A and D are not the best choices as they are not entirely accurate or comprehensive.
