To translate the sentence 'Juan worked in the hospital for six months' in Spanish, we can use either the preterite or imperfect tense depending on the context and time frame of the action. If the action is seen as completed, we use the preterite, and if the focus is on the duration or ongoing nature of the action, we use the imperfect.
Step-by-step explanation:
To translate the sentence 'Juan worked in the hospital for six months' using either the preterite or imperfect in Spanish, we need to determine the context and the specific time frame of the action. If the action of Juan working in the hospital for six months is seen as a completed event in the past, we should use the preterite tense.
