Explanation
Root-level access can be granted in two ways: a UID of 0 in /etc/passwd (which grants root privileges regardless of the username), or an entry in /etc/sudoers (or /etc/sudoers.d/) that allows unrestricted sudo access (e.g., ALL=(ALL) ALL or NOPASSWD: ALL).

The other users (Lee, Eve, Bob, Alice) either have no sudoers entry or have restricted, non-root-equivalent permissions.
