In which of the following sentences is the underlined word or phrase used or placed incorrectly?

a. a ella (les gustan) comer pan y tomar jugo.

b. (le gusta a ella) hablar espanol.

c. se que no (los conoce.)

d. a ella (le gustan) mantequilla y crema

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.

corras is the only one that is informal but doesn't follow the suffix rule. correr is the verb. corre is the formal verb form. corra would be used as the formal is corre ended with an a.

your best bet would be corras, it's the only one that is informal but is still wrong
