Answers:
1. ¿Dónde los compras?
2. ¿Tú las sabes?
3. ¿Ustedes las saben?
4. ¿Ellos la saben?
Step-by-step explanation:
In Spanish grammar, the direct object indicates who directly receives the action of the verb. To identify it in a sentence, we must make the following question:
Que + verbo ?
(What + verb? )
In this context, the Direct Object Pronouns replace a word or phrase, which in the sentence fulfills the function of Direct object. They are written before the verb, when it is conjugated.
These pronouns are listed below:
1st person singular: Yo me
2nd person singular (informal): Tú te
2nd person singular (formal): Usted lo/la
3rd person singular: El/eso lo, Ella/esa la
1st person plural: Nosotros nos
2nd person plural: Ustedes(In latinAmerica) los/las/Vosotros(In Spain) os
3rd person plural: Ellos/Ellas los/las
Knowing this, let's begin with the answers:
1. ¿Dónde compras tú los zapatos?
In this interrogative sentence the direct object is los zapatos, which is the 3rd person in plural they. Hence the corresponding direct object pronoun is los:
¿Dónde los compras?
(Where do you buy them?)
2. ¿Sabes tú las respuestas?
In this interrogative sentence the direct object is las respuestas, which is the 3rd person in plural they. Hence the corresponding direct object pronoun is las:
¿Tú las sabes?
(Do you know them [the answers]?)
3. ¿Saben Uds. las preguntas?
In this interrogative sentence the direct object is las preguntas, which is the 3rd person in plural they. Hence the corresponding direct object pronoun is las:
¿Ustedes las saben?
(Do you know them [the questions]?)
4. ¿Saben ellos la capital de España?
In this interrogative sentence the direct object is la capital de España, which is the 3rd person in singular feminine it. Hence the corresponding direct object pronoun is la:
¿Ellos la saben?
(Do they know it?)
