I would say A.. ending child labor.
Lewis Hine was an activist for the National Child Labor Committee. Mother Jones was a school teacher as well as a female activist. Even though she was most famous for being the founder of the Industrial Workers of the World, I think she would be united with Lewis Hine with ending child labor.
The Immigration Act of 1924 produced highly discriminatory results because it set a max on how many immigrants could come to the US depending on what country they came from.
For example, there were many more opportunities for citizens from countries like Germany, Great Britain, and Sweden in comparison to individuals from Italy or Russia. Here are some numbers to support this claim:
Germany's Quota (aka amount that could come into US)- 51,227
Great Britain and Northern Ireland's Quota- 34,0007
Sweden's Quota- 9,561
Italy's Quota- 3,845
Russia's Quota-2, 248.
