Question

3. yo siempre voy al parque con mis amigos pero ayer no fui. (ir)

Explanation:

Analyze Question 9

The sentence describes ongoing mental states and background actions in the past. "Mis hermanos" (plural) wanting to go to the movies is an ongoing desire, so we use the imperfect of querer: querían. "Mamá" (singular) saying no is also background/ongoing description here, so we use the imperfect of decir: decía.

Analyze Question 10

The sentence describes a past intention that was interrupted by background weather. "Humberto y Paulina" (plural) were going to go, which is an ongoing intention, so we use the imperfect of ir: iban. The weather "it was raining" is background description, so we use the imperfect of llover: llovía.

Analyze Question 11

The sentence contrasts a habitual action in the present ("Yo siempre voy...") with a specific completed action in the past ("pero ayer..."). "Ayer" (yesterday) triggers the preterite tense for a completed action. The first-person singular preterite of ir is fui.

Analyze Question 12

The sentence describes habitual characteristics and preferences in childhood. "Cuando tú eras niño" uses the imperfect of ser (eras) for a past state. "Te gustaba patinar" uses the imperfect of gustar (gustaba) for a past ongoing preference.
