The first option TUVO is in simple past (number: singular; person: 3th: él/ella); the third option TIENE is also in simple present (number: singular; person: 3th: él/ella); finally the last option is presented in infinitive form, which means that it is not a conjugated verb.

<h2>6. Algún día IREMOS a Ecuador</h2>
In this question you need to focus your attention on the CONJUGATION of the verb. The words “algún día” give you the clue that your main verb needs to be conjugated in FUTURE form, so it is IREMOS (number: plural; person: 1st: nosotros).
The first option FUIMOS is in simple past (number: plural; person: 1st: nosotros); the second one VAMOS is in present (number: plural; person: 1st: nosotros); finally the last one VAYAMOS is not in indicative form, so it cannot be the correct one.
