We must conjugate the verbs in each sentence in the correct form:

1) Un dia de primavera, Antonio y Alicia (viajar) por el campo.

Here the sentence is in the past, so we use a preterite, and the person is "nosotros".

Un dia de primavera, Antonio y Alicia viajamos por el campo.

2) (hacer) mucho sol

Here the tense is present, and the person may be "El/ella"

"Hace mucho sol"

3) El cielo (estar) azul.

Again, the person is "el" and the tense is present.

El cielo está azul.

4) Todo se (ver) muy bonito.

Now the tense, again, is present:

Todo se vé muy bonito.

5) De repente, ellos (oír) una explosión.

The person is "ellos", and again the tense is persent:

De repente, ellos oyeron una explosión.

6) El auto (empezar) a temblar

The person is "el", and the tense is preterite.

El auto empezo a temblar

7) Antonio (parar) el auto.

Here the person is Antonio, so is "el", and the tense is preterite.

Antonio paró el auto.

8) Antonio y Alicia (bajarse).

Here the person is "ellos" (because we are talking of Antonio and Alicia), and the tense is preterite.

Antonio y Alicia bajaron.

9) (querer) saber qué pasó.

This may be conjugated in different ways, if the person is "yo" and the tense is preterite, the completed form is:

Quise saber qué pasó.

In the present tense is:

Quiero saber qué pasó

the answer is c. estudió

explanation:

to translate: last year a group from my school went to cuba and studied the history of the island. you would use preterite form because it was one time and they use fue in the sentence.
