I need to know which word to use for each sentence and explain why it’s preterito or imperfecto but just which one to use is fine!

1. Eran (preterito)

2. Entramos (Imperfecto)

3. Iba (preterito)

4. Fuimos (imperfecto)

5. Empezamos (imperfecto)

6. Llego (preterito)

7. Dio (imperfecto)

8. Entendi and estudie (imperfectos)

9. Tomaba, lloro, and estudio (imperfectos)

Explanation:

*Im not completely sure on the preterito and imperfecto answers*

1. Fueron would translate to "it were twelve".

2. Estabamos is past tense.

3. Fue is not gramatically incorrect.

4. Ibamos would indicate that Tomas and you did not go.

5. Empezabamos is gramatically incorrect.

6. Llegaba would be used incorrectly in this sense.

7. Daba is gramatocally incorrect.

8. Entendia is past tense, estudiaba is also past tense.

9. Tome, lloraba, and estudiaba are all past tense.
