I'm not exactly sure what you're asking, but I'll try.
The answer is "compro" because it's past tense. I should know, I speak both Spanish and English.
Mi hermano y yo nos levantamos tarde
Mi madre acaba de maquillarse
Javier y julio entrenan todos los días
Yo me vestí rápidamente
Tu te acostaste temprano
-my first language is Spanish
