women became principals
enrollment numbers tripled
schools hired different teachers for each grade
the number of schools nationwide grew to 2,000
children of all social classes went to school

The two correct answers are:

1. Enrollment numbers tripled: The number of students attending public schools significantly increased during this period.
2. Children of all social classes went to school: Education became more accessible, and children from different social classes were able to attend public schools.

Incorrect. The second option is in fact teachers for each grade

Apologies for the mistake. The two correct answers are:

1. Enrollment numbers tripled: The number of students attending public schools significantly increased during this period.
2. Schools hired different teachers for each grade: Previously, one teacher would often teach multiple grade levels, but during this time, schools started to hire specialized teachers for each grade level.

The correct answers are:

1. Enrollment numbers tripled: Between 1870 and 1920, there was a significant increase in the number of students attending public schools in the United States. This can be attributed to various factors, including increased emphasis on compulsory education laws and the expansion of public education opportunities.

2. Children of all social classes went to school: During this time period, public education became more accessible to children from all social classes. Prior to the late 19th century, education in the United States was primarily limited to the wealthy. However, the implementation of compulsory education laws and the development of public school systems allowed children from all backgrounds to attend school.

To find the correct answers, let's break down the options and examine the changes that occurred in public schools in the United States between 1870 and 1920.

1. Women became principals: While it is true that women played a significant role in education during this time period, becoming principals was not a widespread change. Women did, however, take on more teaching positions and became increasingly involved in education reform movements. Therefore, this option is unlikely to be correct.

2. Enrollment numbers tripled: This is a valid change that occurred during this period. Between 1870 and 1920, there was a significant increase in school enrollment. The introduction of compulsory education laws and the expansion of educational opportunities for various social classes contributed to the rapid growth in enrollment. Therefore, this option is likely to be correct.

3. Schools hired different teachers for each grade: This statement is incorrect. During this time period, the one-room schoolhouse model was still prevalent in many rural areas, where a single teacher taught multiple grade levels simultaneously. The practice of hiring different teachers for each grade level did not become widespread until later in the 20th century. Therefore, this option is unlikely to be correct.

4. The number of schools nationwide grew to 2,000: This statement is incorrect. While the number 2,000 might seem plausible, it significantly underestimates the actual growth. By 1920, the number of schools nationwide had reached well over 100,000 due to the population growth and the expansion of school systems across the country. Therefore, this option is unlikely to be correct.

5. Children of all social classes went to school: This is a valid change that occurred during this time period. One of the main goals of public education during this era was to provide universal education to children of all social classes. As a result, more children from various social backgrounds had access to public schools. Therefore, this option is likely to be correct.

Based on the analysis, the two correct answers are:

- Enrollment numbers tripled.
- Children of all social classes went to school.
