Explanation:

Question 9. The sentence is: "Ellos mandaron la tarjeta a nosotros" (They sent the card to us).

The correct choise is: "Ellos no la mandaron"  (They send it to us).

The sentence: "Ellos te la mandaron" is incorrect because it means: "They send it to you".

The sentence "Ellos nos lo mandaron" is incorrect because "lo" is masculine, and "La Carta" is femenine.

"Ellos se lo mandaron" means: "They send it to him/her" which is also incorrect.

Question 10. The sentence is: "Yo leo los libros a las ninas".

The correct option is: Se los leo.

Question 11. The sentence is: "Yo mande la carta a mi abuela" (I sent the letter to my grandmother). Then:

The correct option is: "Yo se la mande" (I sent it to her)

"Yo me la mande" is wrong because it means "I sent it to me"

"Yo se lo mande" is wrong because "lo" is masculine and "the letter" is femenine.

"Yo te la mande" is wrong because it means "I sent it to you".

Question 12. The sentence is: "Mi abuela trae la cuchara a mi"

"Mi abuela me lo trae" is wrong because "La cuchara" is femenine and "Lo" is masculine.

"Mi abuela me la trae" is the correct option.

"Mi abuela se los trae" is wrong because it means  "My grandmother brings it to them".

Mi abuela te la trae means "My grandmother brings it to you" so it's wrong.

Question 13. En el cine venden las palomitas y los refrescos!

TRUE! You can buy Palomitas (Popcorn) and Refrescos (Soda) in every single cinema!!!
