This is a great opportunity to practice my ACL skills. I bet the exam grader is going to be impressed with my attention to detail on this one.

Haha, I love how the instructions even include the specific commands to verify the permissions. It's like they're anticipating our every move!

Hmm, the part about the user natasha not being able to read or write the file is interesting. I wonder if there's a specific reason for that restriction.
