Final answer:
The student body has changed since 1920 with an increase in college enrollment, growth of public school enrollment, and restrictions placed on women in colleges.
Step-by-step explanation:
The student body has changed since 1920 in several ways. Firstly, there has been a significant increase in the number of young adults attending college. In the early 1900s, only 2 percent of young adults attended college, but by the 1920s, that number had increased to 7 percent. This led to colleges doubling in size and the creation of large university campuses and fraternities and sororities. Additionally, public school enrollment also saw a massive increase, tripling from seven million in 1870 to twenty-one million in 1920. The introduction of larger schools with different teachers for each grade level and the growth of high schools contributed to this increase. Finally, there were societal restrictions placed on women in colleges during this time, limiting their majors and discouraging them from competing both with men and with each other. However, there were still advancements in terms of women's education and opportunities for professional degrees.
