How to explain
Understanding each verb's meaning is crucial: "era" means "was," "tenía" means "used to have," "vivía" means "lived," "iba" means "used to go," "venía" means "used to come," "caminábamos" means "we used to walk," "trabajaban" means "they used to work," "hacíamos" means "we used to do/make," "jugábamos" means "we used to play," "veíamos" means "we used to see/watch," "cenábamos" means "we used to have dinner," and "dormíamos" means "we used to sleep."
By matching each sentence with the corresponding verb from the imperfect list, the text would describe Marco's past routines and habits using the appropriate form of the imperfect tense to convey actions that occurred repeatedly or were ongoing in the past.
