I need to write a command line (only one line), which prints the content of the files of the last modified sub-folder

I have to use grep for this

Hello, sijaanh

Why does it has to be one line?
Why does it has to be grep?
Is this homework?
What have you tried?

This is not a homework.. but a test question and I dont have the answer..
they gave me a hint to use grep expressions such as }[:alpha:] [:alnum:], , ,[:space:][:digit:], ,+,?,-{*,$,^, !

ls -t : this give me the last modified directories by order
I have to get into this folder and print it's files content!
I have no idea where to start from
