We need to fill in the blank of each exercise with the corresponding indirect and direct object pronoun. An Indirect Object Pronoun is a person that receives the action of a verb indirectly. Its purpose is to tell you <em>to whom</em> or <em>for whom</em> something is done. On the other hand, a Direct Object Pronoun replaces a direct object, that is a noun that directly receives the action of a verb in a sentence. See Tables below.

<h2>11) Correct answer:</h2><h3>First blank: me</h3><h3>Second blank: las</h3>

In this sentence, the action of the verb is being performed <em>for me, </em>so we must use the indirect object pronoun that matches the first person singular, which is me. On the other hand, the direct object in this sentence is las cartas, so we must use the direct object pronoun for the third person singular (feminine form), which is las. Finally, we have the following sentence:

<em>Usted</em><em> me las</em><em> da</em>

<h2>12) Correct answer:</h2><h3>First blank: se</h3><h3>Second blank: lo</h3>

If the indirect object le and les is followed by the direct object pronoun lo, la, los and las, then the indirect object changes to se. Since in this sentence the action of the verb (to buy) is being performed <em>for las personas </em>(for them), we must use les that changes to se according to the previous rule because the direct object pronoun is lo that replaces the direct object el pan. Finally:

<em>Nosotros </em><em>se lo</em><em> vendemos</em>

<h2>13) Correct answer:</h2><h3>First blank: se</h3><h3>Second blank: la</h3>

Here los hermanos Vega receive the action of the verb to sell (vender) indirectly, so the action of the verb in this sentence is being performed <em>for them</em>, that's why we choose les here that changes to se. On the other hand, the direct object here is la casa, hence the direct object pronoun we need to use is la. Finally:

<em>Felipe </em><em>se la </em><em>vende</em>

<h2>14) Correct answer:</h2><h3>First blank: nos</h3><h3>Second blank: la</h3>

Here we receive the action of the verb to show (mostrar) indirectly, so the action of the verb in this sentence is being performed <em>for us</em>, that's why we choose nos. On the other hand, the direct object here is la revista, hence the direct object pronoun we need to use is la. Finally:

<em>Lupe </em><em>nos la </em><em>muestra</em>

<h2>15) Correct answer:</h2><h3>First blank: se</h3><h3>Second blank: la</h3>

Here Javier receives the action of the verb to buy (to buy) indirectly, so the action of the verb in this sentence is being performed <em>for Javier (for him)</em>, that's why we choose le here that changes to se according to the rule indicated in 12. On the other hand, the direct object here is la manzana, hence the direct object pronoun we need to use is la. Finally:

<em>Ella </em><em>se la </em><em>compra</em>
