You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The American Federation of Labor (AFL), a coalition of labor unions formed in the 1880s, vigorously opposed unrestricted immigration from Europe for moral, cultural, and racial reasons. The issue unified the workers who feared that an influx of new workers would flood the labor market and lower wages. Nativism was not a factor because upwards of half the union members were themselves immigrants or the sons of immigrants from Ireland, Germany and Britain. However, nativism was a factor when the AFL even more strenuously opposed all immigration from Asia because it represented (to its Euro-American members) an alien culture that could not be assimilated into American society. The AFL intensified its opposition after 1906 and was instrumental in passing immigration restriction bills from the 1890s to the 1920s, such as the 1921 Emergency Quota Act and the Immigration Act of 1924, and seeing that they were strictly enforced.Mink (1986) concludes that the link between the AFL and the Democratic Party rested in part on immigration issues, noting the large corporations, which supported the Republicans, wanted more immigration to augment their labor force.United Farm Workers during Cesar Chavez tenure was committed to restricting immigration. Chavez and Dolores Huerta, cofounder and president of the UFW, fought the Bracero Program that existed from 1942 to 1964. Their opposition stemmed from their belief that the program undermined U.S. workers and exploited the migrant workers. Since the Bracero Program ensured a constant supply of cheap immigrant labor for growers, immigrants could not protest any infringement of their rights, lest they be fired and replaced. Their efforts contributed to Congress ending the Bracero Program in 1964. In 1973, the UFW was one of the first labor unions to oppose proposed employer sanctions that would have prohibited hiring illegal immigrants.
Output:
What were the full names of the people whose opposition stemmed from their belief that the program undermined U.S. workers and exploited the migrant workers?
