<h3>Fill in the blank with the correct form of preterite or imperfect of the verb in parentheses. Tú Answer (used to be) bajo. (ser)</h3>
Answer: Tú eras bajo.
Translation: You used to be short.
Explanation: If the action of the verb in the past was habitual, then the correct verb tense is imperfect. Since the subject in this sentence is "Tú", that is second-person in the singular, so the correct form is: Tú eras.
