Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation
Context: Same Latino advocacy groups passage, with Mexican American Political Association (1960) and Partido Nacional de La Raza Unida (1970). Period ends first sentence; "Established" begins new sentence.
Answer: D) groups. Established
Why? Period after "groups" ends the first sentence. "Established to protect and advance the rights of Latino Americans, both [organizations] contributed to the history of US civil rights" is a new sentence with a participial opener.
Traps:
- A) "groups and established" → creates grammatical awkwardness
- B) "groups, established" → comma before participial phrase modifying "groups" — incorrect
- C) "groups established" → run-on
