Answer:
The correct direct object pronouns that fill the blanks are:
1. Los viajeros compran <u>los</u> pasajes. Ellos <u>los</u> compran.
2. La viajera confirma <u>la</u> reservación. Ella <u>la</u> confirma.
3. El empleado tiene <u>las</u> llaves. Él <u>las</u> tiene.
4. Yo escribo una carta. Yo <u>la</u> escribo.
5. Alejandra pierde el equipaje en el aeropuerto. Ella <u>lo</u> pierde.
Explanation:
In Spanish, <em>some direct object pronouns are similar to the articles</em>, in the first three sentences I underlined the articles because those are the same word that the direct object in the contract sentence; in the fourth sentence, the article is undefined "una" but continues referencing to <em>a female object</em>, by this reason, the direct object pronoun is "la" and the last sentence, the subject "el equipaje" is <em>a male object</em>, then its direct object pronoun is "lo".
Question 9 bebemos, question 10 voy, question 11 llegan, question 12 van.
It appears to be asking for affirmative and negative of tú command.
Tú affirmative: same as indicative present tú (exa: comer to comes)
Tú negative: indicative tú command, change a to e, e to a(ar to er/ir ending, er/ir to ar ending)(exa: comer to no comas, acabar to no acabes)
Use the base word of subjunctive present first person(jueg of guegue)to be the base in commands to remember irregulars, because stem change along with a whole bunch of other changes apply to command and subjunctive indicative, Da!!!
