el fin de semana pasado fui a visitar a mi abuela lilia en el campo

When it comes to this assignment, what you need to do is place each of these verbs in the correct form, which in this case is the Spanish preterite. For regular verbs, you just delete the infinitive part -ar, -ir, -er and add the suffix é. Unfortunately, when it comes to irregular verbs, you have to memorize them by heart. So, this is how this should be done:

1. conseguí - the verb consequir is irregular, which means you have to learn it; however, most of these irregular verbs end in í, which can help you in the long run (it means to borrow)

2. pidió - the verb pedir is also irregular, and third person singular (he, she, it) always ends in ó in the preterite form (it means to ask for)

3. sirvió - the verb servir is irregular, and it is conjugated similarly to pedir (it means to serve)

4. murió - the verb morir is irregular, and as you can see here, it also ends with ó in the third person singular (it means to die)

5. dormí - for the verb dormir (=sleep), you just add -í at the end to create the right form for first person singular

6. se visitó - it means visited and this verb is reflexive in Spanish (the pronoun se is used)

7. seguí - the verb seguir means to follow

8. repitió - means to do something again, in this case - to ask again

9. prefirió - means to prefer

10. me sentí - means to say goodbye
