Issue description: 

I noticed a technical inconsistency in the video "Managing File Permissions from the Command Line (32)" at 11:32. The instructor states that "Read and Execute" permissions on a directory are sufficient to delete a file. However, write (w) permission on the parent directory is strictly required to remove a file entry.

In the demonstration, the user "alexis" can only delete the file because the directory /data was set to 057, granting write access to "Others". The verbal explanation might confuse students regarding the necessity of the 'w' for deletion tasks.
