Explanation:

Question 1

The subject is "tú", and the verb "ir" (to go) in the preterite tense for "tú" is "fuiste". The original "fueron" is incorrect as "fueron" is for "ellos/ellas/ustedes". So we correct it to "fuiste", and the infinitive is "ir" (since it's about where you went, related to movement).

The sentence is about Marcos and Silvia being boyfriend and girlfriend for two years, so we use "ser" (to be, for identity/relationship). The preterite tense of "ser" for "ellos" (Marcos y Silvia) is "fueron" (wait, no: "ser" preterite for "ellos" is "fueron"? Wait, no: "ser" preterite conjugations: yo fui, tú fuiste, él/ella/Ud. fue, nosotros fuimos, vosotros fuisteis, ellos/ellas/Uds. fueron. And "ir" preterite: yo fui, tú fuiste, él/ella/Ud. fue, nosotros fuimos, vosotros fuisteis, ellos/ellas/Uds. fueron. Wait, but the context here is "ser" (relationship). So "Marcos y Silvia fueron novios por dos años." Wait, no, "ser" for relationship. Wait, maybe I made a mistake. Wait, "ser" preterite: for "ellos" (Marcos y Silvia), "ser" preterite is "fueron". So the correct form is "fueron" (from "ser"), and the infinitive is "ser" (since it's about being novios).

The subject is "yo", and the verb is "ir" (to go) in the preterite tense. The preterite of "ir" for "yo" is "fui". So we use "fui", and the infinitive is "ir" (since it's about going to the bathroom).

Answer:

1. ¿Adónde fuiste tú después de la clase de español? (Infinitive: ir)
