4.Permissions - scenario2 question3&4

My question is regarding the 2nd scenario. Since all files mentioned are assumed to be in /home/dq . My question is how could the user “learn” owns this file? What sense does the fact that the user “learn” owns a file which locates in another directory make??

  1. Second scenario. User learn owns a file whose permissions are rwxr-xr-x.
  • Question 3. Can dq modify the contents of this file?
  • Question 4. Can dq rename this file?
