Question

Ayer yo (ir) al parque con mi perro.

Answer 1

Answer:

Ayer yo fui al parque con mi perro.

Explanation:

The verb must be conjugated in the past tense, since in the sentence it is described that the action was carried out in the past tense, so it is important to identify the subject, gender and number in a sentence so it is possible to conjugate the verb correctly and that be consistent with what you want to express.
