Analyze the subject pronouns

The sentence has two subjects: "José" (third-person singular, él) and "yo" (first-person singular).

Conjugate the verb "ir" in the imperfect tense

• For "José" (él): iba
• For "yo": iba

Match with the options

Both blanks require the form iba, which corresponds to the first option: "iba, iba".
