Yo use Spanish Dict and translate it all to English
Iempo que expresa una acción pasada cuya terminación se considera anterior al lapso de tiempo más o menos extenso en que hablamos
1 falsa
2 verdadera
3 verdadera
4 verdadera
5 verdadera
You use preterite to describe an action that took place and was fully done, Ex. José entro a la habitación, you can see John went into the room, he completed the action. On the other hand, imperfect tense doesn't specificate if the action was completed, Ex. José entraba a la habitación, it doesn't tell us if José fully entered the room.
