Clarification:
I searched the exercise on Google and it says the verbs have to be in the preterite tense.
Answer:
1. Ellos buscaron (buscar) el mercado.
2. El dependiente vendió (vender) una camisa.
3. Nosotros escribimos (escribir) cartas a nuestros amigos.
4. ¿Tú pagaste (pagar) en efectivo por la ropa interior?
5. Juan llegó (llegar) ayer de su viaje a la playa.
Step-by-step explanation:
In this exercise, you have to put the verbs in brackets in the correct form so they fit the sentences. The verbs have to be in the Spanish preterite tense ("pretérito perfecto simple" in Spanish), which is used to talk about actions completed at some point in the past.
