Question

la obra ( empezaba / empezó ) a las cinco de la tarde y ( terminaba / terminó ) a las ocho de la noche.
empezaba / terminó
empezaba / terminaba
empezó / terminó
empezó / terminaba

Explanation:

To solve this, we analyze the verb tenses. "Empezó" (preterite, action with definite start/end) fits "a las cinco de la tarde" (specific time for start). "Terminaba" (imperfect, ongoing action) fits the context of the work's end time being at eight, implying an ongoing action leading to that. Wait, no—wait, the first blank: "La obra (empezaba / empezó) a las cinco de la tarde"—preterite "empezó" is correct for a completed action at a specific time. The second blank: "y (terminaba / terminó) a las ocho de la noche"—"terminó" is preterite for a completed action at a specific time? Wait, no, maybe I misread. Wait the options are "empezó / terminó", "empezaba / terminaba", etc. Wait the correct pair: "empezó" (preterite, started at 5) and "terminó" (preterite, ended at 8) are both preterite, actions with definite times. Wait the option "empezó / terminó" is one of the choices. Let's check the options: the third option is "empezó / terminó". So the correct answer is the option with "empezó / terminó" because both actions (starting and ending) are completed at specific times (5 pm and 8 pm), so preterite is used.

Answer:

empezó / terminó (the option labeled as "empezó / terminó" among the choices, e.g., if it's the third option, then the answer is the option with "empezó / terminó")
