[Done] Read the excerpt from activist Cesar Chavez's 1984 address to the Commonwealth Club of San Francisco. All my life, I have been driven by one dream, one goal, one vision: To overthrow a farm labor system in this nation which treats farm workers as if they were not important human beings. Farm workers are not agricultural implements—they are not beasts of burden to be used and discarded.... My motivation comes from my personal life—from watching what my mother and father went through when I was growing up—from what we experienced as migrant farm workers in California. That dream, that vision, grew from my own experience with racism—with hope—with the desire to be treated fairly and to see my people treated as human beings and not as chattel. Which ideas from the excerpt would be most appropriate to include in a summary? Select two options. A. My singular objective has been to change farming practices so workers are respected. B. There was a time when people like me were not welcome in restaurants or theaters. C. I have been angry for at least 40 years because of horrible experiences in my life. D. This dream for change came from my own experiences of racism and mistreatment. E. My dreams for change came from watching my parents as I was growing up.
