Help understanding Spanish school question?

Hey guys, I'm trying to finish my midterm spanish exam. I'm not sure what this question wants me to do...

Write the sentences Margarita would say to indicate that she has completed the errand specifiedin the prompt. Use the appropriate direct object pronouns (lo, los, la, las).

Modelo sacar un libro de la biblioteca Lo saqué.
echar una carta

I'm not sure what "modelo" means, but I understand it to be something about going to the library and writing a letter?? Any help much appreciated

Hello LevTheMan,
In this case, "modelo" means the example or guide for you to answer following the sentece: "sacar un libro de la biblioteca-Lo saqué."

As Danielr said, "modelo" means example.

Sacar un libro de la biblioteca /Lo saque
In this sentence you use the "Lo" pronoun.

Echar una carta /** eché
Which pronoun you think goes there?

Its actually really simple...
