The correct verb form to complete the statement "Ellos siempre la misma cosa." would be:
- decían
Explanation:
1. The sentence "Ellos siempre la misma cosa." implies an ongoing or repeated action in the past, which aligns with the imperfect tense in Spanish.
2. The verb "decían" is in the imperfect tense and matches the subject "Ellos" (They).
3. The verb "dijeron" is in the preterite tense, which is typically used for completed actions in the past. Since the sentence suggests a habitual action, the imperfect tense "decían" is more suitable in this context.
Therefore, the correct verb form to complete the statement would be "decían."
