5) What happened to Article X?

6) Born in Nueces County, I was a civil rights leader for Mexican-Americans in the early 20th century and held various political offices, including state representative for South Texas (1905-10 and 1917-20), Cameron County superintendent of public schools (1912-14) and county judge (1914). Who am I?

7) But perhaps my greatest notoriety came when I fought to hold what statewide organization accountable for its treatment of Mexican-Americans. What was that organization?

8) I also was instrumental in the formation of the League of United Latin American Citizens and argued at its formative 1927 convention that Mexican citizens should be excluded from LULAC. Where was that convention held?
