Hello can someone help we with the lab below? I'm unfamiliar with Linux

Part 1: Basic User Account Management - A Warmup In this part of the lab, you will be the root administrator and will create a shared folder for two users from different groups. Goal: 1. Create two user accounts for Bob and Alice (you can use your own names, but name like Bob and Alice are always used when we talk about cryptography/cyber security). Bob and Alice are normal users and belong to their own group (same name with the username). As both Bob and Alice will be working together on a project located at /srv/smartcar. Add them both to another project group (they should belong to both the "project" group and their own group) and make sure the project folder /srv/smartcat is inaccessible for any other account on the Operating System. 2. To accomplish this part, you must also test if your solution reaches the goal. 1. Create a third account and check if the account can access/remove the project directory or 2. Test if Bob and Alice can access, read, write, create a file in the directory. modify the permission on the directory. 3. Of course, it is your responsibility to describe the whole process and taking screenshots as proof
