Would 'Inspect some Mondays' work for #4?

I really hate this one for the amount of outside information you're supposed to bring in. How would I be know that no copies were made and even if there were, why would I assume anyone other then the actor(s) have one?

For #4 I used 'AI & CI --> Good j'. The explanation shows that you do not have to use the AND. I am curious about what a valid contrapositive would be since you do not have to use AND. Do you have to use De Morgan's law here or can I just negate 'acc-info-sub-int → good' the more common way to negate a conditional statement?
