Answer: I'm not sure if these are right but:
* Ella escribió en el libro
* Llame a mi abuela
* Vendemos la casa para ti
* Lanzastes la pierda al mar para mi
* Ellas se la dieron
Explanation:
Basically, what you're doing is simplifying the sentence to make it shorter and plainer. For example, "Ellas dieron una clase interesante a mi madre."
(They gave an interesting class to my mother.) When we simplify the sentence, we can say "Ellas dieron una clase interesante." (They gave an interesting class), since it's a complete thought.
Again, I'm so sorry if it's wrong, but I hope this helps in a way.
