Question

Ayer yo _________ que empezaste a trabajar.
a. supimos
b. supe
c. supo
d. supieron

Answer 1

Hello!

This sentence is in past tense. The trigger word was "ayer", meaning yesterday. The preterite tense is different from present tense. In this case, since the subject is "yo", or "I", the conjugation is -é.

Therefore, the answer is B, Ayer, yo supé que empezaste a trabajar.

Answer 2

Hi !!

Ayer yo supe que empezaste a trabajar. (empezaste = pretérito perfecto simple "tú")

SABER (pretérito perfecto simple)

supe (yo)

supiste (tú)

supo (él/elle/Ud)

supimos (nosotros)

supisteis (vosotros)

supieron (ellos/ellas/ Uds)

hope this helps :)
