b-Today, I go to Korea
C-Do you live in Korea?
​

Answer 1

Resposta:

a- last year did I not travel to Korea?

b- Did I go to Korea today? (não sei se tem que mudar de "hoje" p ontem, mas se vc souber é só mudar "today" e por "yestarday"

c- Did you live Korea?

Answer 2

Hello. The sentence which is in the Past Simple Tense is letter A:

→ Last year, I didn't travel to Korea.

I could be (withiut changing the meaning):

→ Last year, I did not travel to Korea.

Just don't contract the "did not" to "didn't".

If you have "did" in a sentence (positive, negative or interrogative) the sentence will be in the Past Simple Tense.

Letters B and C aren't on Past Simple because they are in Present Simple...

→ Today, I GO to Korea.

→ DO you live in Korea?

"Do" and "go" are verbs (do in this case is an auxiliary verb) in their Present Simple Tense.

Hence, having it all in mind, correct alternative:

A) Last year, I didn't travel to Korea.

Enjoy your studies.
