Hello, I am a Spanish Speaker and would like to help you. So, let's start with the definition. A Direct Object Pronoun (un pronombre de objeto directo) replaces a direct object, that is a noun that directly receives the action of a verb in a sentence. Moreover, direct object pronouns in Spanish agree in number and gender with the nouns they replace. The Table below shows the different forms of direct objects in Spanish. On the other hand, there are two places where indirect object pronouns can be placed namely:
1) Before a conjugated verb.
2) Attached to the end of the verb. This is only true if the verb is not conjugated, such as infinitives or gerunds or if the verb is an affirmative informal command.
In this way, let's solve this problem:
1. The right answer is te
Nosotros te vimos.
2. The right answer is me
¿Tú me llamaste?
3. The right answer is parar whose translation is stop, so you might say:
Por favor, para de sonar esa trompeta<em> (Please, </em><em>stop</em><em> ringing that trumpet.)</em>
Para de llorar <em>(</em><em>Stop</em><em> crying)</em>
Para de reir <em>(</em><em>Stop </em><em>laughing)</em>
4. The right answer is ¿Cómo se va a la carretera?
You can also say these equivalent sentences:
¿Cómo llego a la carretera/autopista?
¿Cómo agarro la carretera/autopista?
¿Cómo cojo la carretera/autopista?
¿Cómo tomo la carretera/autopista?
5. The right answer is Déjame en paz.
You can also say these equivalent sentences:
Déjame solo.
¡vete!
¡lárgate!
