Final answer:
In a summary, it would be appropriate to focus on Chavez's goal to reform farming practices to respect workers and his motivation stemming from personal encounters with racism and injustice.
Step-by-step explanation:
The ideas from Cesar Chavez's 1984 address to the Commonwealth Club of San Francisco that would be most appropriate to include in a summary are 'My singular objective has been to change farming practices so workers are respected' and 'This dream for change came from my own experiences of racism and mistreatment'. These statements encapsulate Chavez's lifelong commitment to improving the lot of farm workers and the personal experiences that fueled his activism.
Born into a migrant farm family, Chavez witnessed firsthand the exploitation and racism faced by farm laborers. Together with Dolores Huerta, Chavez founded the United Farm Workers (UFW) to advocate for these workers’ rights. Drawing inspiration from the civil rights movement, they led boycotts and strikes, such as the notable grape strike in California, to achieve significant reforms including union recognition and improved wages and conditions by the 1970s.
