Fuimos al resturante y comimos pasta.
I was doing some exercise on past tense on Spanish language and this very first question made me confused that how this is a past tense.
The application on my mobile said the right answer was
We went to the resturant and ate pasta.
But why cannot this be
We go the resturant and eat pasta.
I don't know the way it has been constructed so that it has become a past tense.
