7. The Astros won the World Series.
8. The store opened at 10:00AM.
Step-by-step explanation:
3. Kristina and Lucia attended a wedding last summer.
In this exercise we should put the verbs into the preterito. The option asistir cannot be chosen as it is the infinitive form of the verb. Asisten is the present form of the verb and should not be considered. The first option, asistaron, uses the incorrect ending for the preterito. Therefore we choose the right form which is asistieron.
4. Noé and I learned to bowl last year.
The subject of this sentence, Noé y yo, requires a first person plural form of the verb. Therefore, we do not take aprendieron into consideration. Aprendí neither, since it is the form for the first person singular. The last two forms we have left are in the right person and number, but aprendemos is in the presente. The only option here is aprendimos.
5. Miguel bought leather trousers last night.
The verb comprar means to buy. The infinitive form is again among the options but do not consider it. A verb must be conjugated in the right person as well as to match the nouns in number. Compra is in the third person singular but in the present tense. Compré and compró are both in the preterito but only compró.
6. Did you sell your wool scarf?
Vender is an infinitive form and again cannot be used. What we need here is a second person singular form. Vendes is the present tense, so we have to choose between vendaste and vendiste. The form vendaste is non-existent since the preterito endings are wrong. The correct form we should use here is vendiste.
7. In order to choose the right translation, we must analyse the verbal form. Ganaron is the verb ganar, to win, in the third person plural of the preterito. The preterito illustrates an action having taken place in the past. That is why the only right option is the English sentence in the Past Simple.
8. Here again we focus on the verbal form in order to choose the right translation. Abrió is in the third person singular of the verb abrir, meaning to open. It is in the preterito and expresses an action that was executed in the past. Therefore, the only correct sentence is the forth one, the store opened.
