Answer:
The possible conjugation of the verb between parentheses is:
- <em>Tú </em><em><u>eras</u></em><em> bajo.</em>
Explanation:
The translation of the sentence is:
- You <u>were</u> short.
The sentence proposed in Spanish could have two conjugations of the verb <em>"ser"</em>:
- <em>Tú </em><u><em>eras</em></u><em> bajo.</em>
- <em>Tú </em><em>fuiste</em><em> bajo.</em>
In <u>the first the verb is conjugated in its </u><u>Imperfect Preterite</u> form and in <u>the second is conjugated in the </u><u>Perfect Preterite</u>. You could even perform a sentence that used the verb <em>"ser"</em> in its infinitive form:
- <em>Tú </em><em><u>solías ser</u></em><em> bajo.</em>
However, making correct use of Spanish grammar, <u>it is identified that the correct conjugation belongs to the Imperfect Preterite</u>, because it is used when the actions mentioned are not defined in time, I mean, it is not written when they start or when they end, as is the case with the sentence in the answer.
