1) Correct answer:
entre
Entre is a preposition that means between. A preposition is a word or group of words we use to show how other words are connected and this indicates a relationship between two words or phrases, between nouns, between nouns and verbs, and also between different parts of a sentence. So we can write this sentence as follows:
La chica estaba entre su padre y su primo en la foto.
2) Correct answer:
era
used to be conveys the idea of a sentence in the imperfect. So if we talk about actions that occurred frequently or in progress in a certain point in the past, we use the imperfect. So era matches the subject pronoun yo in the imperfect. Finally, we can write the sentence as follows:
Yo era gorda
3) Answer:
Correct conjugation in the imperfect: salía
Correct conjugation in the preterite: salió
Unless the imperfect, the preterite tense is used when talking about action that occurred at a certain moment in the past, not in progress, but sentences that were completed. So, the sentences can be written as follows:
Imperfect:
Usted no salía a las dos.
Preterite:
Usted no salió a las dos.
