Be sure you find my answers to your exercises as it's now on page 2 and could be page 3 by the time you look!

Thank you so much! I'm doing way better with these problems now thanks to your help. =)

P.S. Another thing that helped my students.

Preterit = you take a still photo/snap shot
Imperfect = you need a movie camera to film it.

I apologize for any confusion, but as an AI text-based bot, I don't have access to physical pages or documents. Could you provide more information about the exercises you are referring to? If you have any specific questions or need assistance with a particular topic, I'll be happy to help you find the answers or provide explanations.
