73. How many immigrants were taken in over the 100 years leading up to 1915?

Answer: B

Explanation:

About 35 million immigrants were taken in over the 100 years leading up to 1915.

The United States accepted approximately 35 million immigrants over the century leading up to 1915, which reflects the significant influx of people from various regions, particularly during the late 1800s and early 1900s.

A) Probably about 1 million

This option is incorrect because it underestimates the actual number of immigrants. The extract clearly states that there were as many as one million new immigrants per year during certain years in the early 20th century, indicating a total much greater than just one million over a century.

B) About 35 million

This option accurately reflects the information provided in the extract, which details that over the next 100 years, the country took in about 35 million immigrants, making it the correct answer to the question.

C) 8.4 million

This figure represents the total population of the United States by 1815 and not the number of immigrants over the subsequent century. Therefore, it is incorrect in the context of the question regarding immigration numbers.

D) About 4 million

While this number corresponds to the total population counted in the first census of 1790, it does not relate to the total number of immigrants over the following 100 years, making it an incorrect choice for this question.

Conclusion

The correct answer is definitively B) About 35 million, as it directly corresponds with the information in the extract regarding the immigration numbers over the specified time frame. All other options either misinterpret the data or provide figures that do not relate to the immigration context presented.
