Analyze the first sentence

The verb "compraba" is in the imperfect tense, which describes habitual or ongoing past actions. "Cada año" (every year) triggers the imperfect tense, whereas "ayer" (yesterday) triggers the preterite tense.

Analyze Question 14

The verb "mandé" is in the preterite tense, which describes completed actions at a specific point in time. "Ayer por la tarde" (yesterday afternoon) triggers the preterite tense, whereas "todas las tardes" (every afternoon) triggers the imperfect tense.

Analyze Question 15

The verb "fuimos" is in the preterite tense, which describes a completed action in the past. "Este verano" (this summer) refers to a specific, completed timeframe, whereas "todos los veranos" (every summer) triggers the imperfect tense.
