¿A qué se debió el incremento en la cantidad de oxígeno en la atmósfera hace miles de millones de años?

Spanish

Scientists think that algae first evolved approximately 2.7 billion years ago, and soon after this oxygen began to exist in the atmosphere. Photosynthesis by primitive plants and algae released oxygen, which gradually built up in the atmosphere.

¿Nos conseguiste las revistas? Sí, __
VashaNatasha [74]

The blank must be filled with the correct direct object pronoun. In Spanish, when replacing a noun with a direct object pronoun, the verb will come after the direct object pronoun, and essentially switch positions with the original noun. Further, the direct object pronoun that replaces the object will be the same definite article.


    ¿Nos conseguiste las revistas?

    Sí, se las conseguí.


The literal translations of these sentences are:


    "Did you get us the magazines?"

    "Yes, for you them I got."


This is because the verb and object switched places when using the direct object pronoun. Notice, also, that the definite article is las, thus las replaces the noun.


The rest of the direct object pronouns:


    ¿Le trajiste los refrescos a Roberto?

    Sí, se los traje.


    ¿Le compraste la comida a Elena?

    Sí, se la compré.


    ¿Les trajiste los helados a los niños?

    Sí, se los traje.


The object of each of these sentences is "him," "her," or "them." Each of these forms (along with the formal "you" in Spanish [usted]) are replaced with se.

The other form is te, which replaces tu (or me when a question is being asked). For example:

    ¿Me trajiste las cartas?<span>    
</span><span>    Sí, te las traje.

</span>

I hope this helps!
