5. Correct answer:
fuimos
This sentence is given in the past because of the word ayer that means yesterday. In fact, this sentence stands for the preterite tense. The preterite tense is one of two simple past tenses. It is used to describe actions that took place or were completed at a certain point in the past. So fuimos is the conjugation of the irregular verb ir that matches the first person plural in the preterite. Finally:
Ayer nosotros fuimos a la ciudad de México (We went to Mexico City yesterday)
6. Correct answer:
era
We choose the word era (a conjugation of the verb ser) because it stands for the third person singular in the imperfect tense. In general, the imperfect is used to talk about past actions, conditions, or events that occurred regularly or frequently or that were in progress in a moment in the past. So the verb ser is being used here as description, talking about a quality of a place. Finally:
La ciudad era muy bonita (The city was very beautiful)
7. Correct answer:
era
When telling the time in the past, we use the verb ser conjugated in the imperfect tense. So we use era when referring to one o’clock and use eran when referring to all other hours. So here la una means one o’clock, hence we use era. Finally, this sentence can be written and translated as follows:
Era la una de la tarde (It was one in the afternoon)
8. Correct answer:
todo el camino derecho
There are several forms we can use when telling a person to continue straight ahead, so a common expression is todo el camino derecho. Therefore, we can address a person and say:
Siga todo el camino derecho
Continúe todo el camino derecho
Avance todo el camino derecho
9. Correct answer:
al lado de
Al lado de is a preposition that can be translated as beside, next to. Recall that a preposition is a word (or group of words) which is used to show the way which other words are connected, that is, they are used to indicate a relationship between two words or phrases, between nouns, between nouns and verbs, and between different parts of a sentence. We often use them to indicate relationships of location, direction, or time. So here this preposition indicates relationships of location.
