Have to choose between preterito and imperfecto version. Please Help!!!

I won't be answering all of them but the first one is the imperfect.

Explanation: Remember that the preterit is a one time thing, it's a completed action, sequence of events or interrupted action. The imperfect on the other hand are repeated actions that didn't have a definite beginning or end, they happened periodically. Your teacher must have given you a flag chart that consists of words that signal whether a verb is in the preterit or imperfect. Use the flag chart, if your teacher didn't give you one, look one up online and use it, it's very crucial to know the flag words!
