Final answer:
Having read permission on a directory allows you to view its contents, but not modify or delete them.
Step-by-step explanation:
Having read permission on a directory allows you to view the contents of that directory.
For example, if you have read permission on a directory called 'Documents', you can see the files and folders inside the 'Documents' directory.
However, having read permission does not allow you to modify or delete the files or folders in the directory.
