What is the difference between preterite and imperfect and the past progressive and present progressive?

Preterite and imperfect are both verb tenses used for the past in Spanish. There are many different reasons to choose between the two, some of my go-tos are that the imperfect is used to describe an action that is repeated over time, such as "I ate bananas every morning" "comía bananas cada mañana" while the Preterite is an action that only occurred once, such as "I ate a banana" "comí una banana". You'll notice that imperfect verbs usually end in ía or aba

12- c13- d14- a or b15- a16- di could be wrong on these so if someone else comments go with their comment

This doesn’t make sense
