Answer:
I think they have a different language
To complete this sentence, I am certain the missing word is "vamos"
Cantaba is the correct imperfect tense for the word in parentheses.
The translation is “After eating tamales my friends sang(cantaba) a lot” Cantar means to sing and cantaba means “sang”. Sang makes it past tense, so it makes more sense in the sentence as well.
Hopefully this helped :)
