Answer:
17. se ahogó
19. trajimos
Explanation:
Let's first start with #17.
The sentence is: El gato de María ______ en el lago porque no sabía nadar.
We want to conjugate the verb ahogarse in the preterite to match the sentence.
In this case, the subject is El gato de María (María's cat), which means that it is in third person singular (it will use the él/ella/usted conjugation).
For reflexive verbs (that have 'se' at the end), we conjugate both the object pronoun, as well as the verb itself.
The object pronoun used for the third person singular is 'se'.
Now, we need to conjugate the verb (ahogar).
Since it is a regular -ar verb in third person singular, the ending will be ó.
Replace ar with ó.
Ahogar --> ahogó
Remember to add the object pronoun in front. Therefore, the correct preterite form of this verb is se ahogó.
The full sentence will be:
El gato de María se ahogó en el lago porque no sabía nadar.
Now on to #19.
The sentence is Mi familia y yo _______ las bebidas para la fiesta de aniversario de mis abuelos.
We need to conjugate traer.
The subject in this sentence is 'Mi familia y yo', which is 'my family and I'. This uses the first person plural conjugation (the conjugation for nosotros/as).
However, traer is irregular in the preterite tense. The forms are:
yo traje
tú trajiste
él/ella/usted trajo
nosotros/as trajimos
vosotros/as trajisteis
ellos/as/ustedes trajeron
Therefore, the correct form for the sentence will be trajimos.
The full sentence will be:
Mi familia y yo trajimos las bebidas para la fiesta de aniversario de mis abuelos.
