In this problem we need to complete the conversation with the appropriate verb forms. In this exercise we will use the present tense. In Spanish, we use this tense to talk about habitual actions, routines, things happening now or in the near future, universal truths, facts, hypotheticals, lapses of time, and for ordering in restaurants and stores. There are both regular and irregular indicative forms.

For regular forms you can recognize some endings for regular verbs, one for ar verbs, one for er verbs and one for ir verbs. Thus, if you want to conjugate an ar verb, take away the infinitive ending ar and add the ending that matches the subject. On the other hand, if you want to conjugate an er verb, remove the infinitive ending er and add the ending that matches the subject. Finally, to conjugate an ir verb, take away the infinitive ending ir and add the ending that matches the subject.

On the other hand, for irregular forms, there are some changes when using the present tense yo conjugations, so these changes build up the irregular form. In this way, verbs ending in guir, ger, or gir undergo a spelling change in their present tense yo forms. First, for verbs ending in guir, the yo form ends in go. Second, for verbs ending in ger or gir, the g in the yo form changes to a j. On the other hand, there are some exceptions regarding ar, er and ir verbs, so there are some of these types of verbs that have an irregular form.

Therefore, we can solve this problem by using the correct conjugation of each verb in each sentence:

Pablo: Óscar, voy al centro ahora. ¿quieres venir?

Óscar: No, yo los fines de semana prefiero descansar un poco y mirar la televisión.

Pablo: ¡Qué perezoso eres!

Óscar: No, hombre. es que yo no duermo mucho de lunes a viernes. Vuelvo a casa a la medianoche.

Pablo: Lo siento. ¿y piensas ver el partido de fútbol hoy? Empieza a las cuatro.

Óscar: ¡Por supuesto! ¿y tú?

Pablo: yo también. ¿Piensas que that nuestro equipo puede ganar?

Óscar: Claro que sí. ¡los pumas pierden hoy! nuestro equipo juega mucho mejor.
