The sentence "Compro la gasolina en la estación de servicio" can be rewritten using a direct object pronoun as:
"La compro en la estación de servicio."
In this case, "la" is the direct object pronoun that substitutes "la gasolina."
Explanation:
- Direct Object Pronouns: In Spanish, direct object pronouns replace direct objects (the noun that receives the action of the verb).
- Recognition of Gender and Number: "Gasolina" is a feminine singular noun, so we use the pronoun "la," which is the feminine singular form for direct object pronouns.
- Placement: In this sentence, the pronoun "la" is placed before the verb "compro." This is a common structure when using direct object pronouns in Spanish.
Therefore, by substituting "la gasolina" with "la," we maintain the meaning of the sentence while using the direct object pronoun.
