Answer:
mkdir Archive
Explanation:
Assuming that you want to create the new folder within the Old_Data folder then you would only need one command which is the mkdir command. This will create the folder inside the current location which in this case is the Old_Data folder. Like so...
mkdir Archive
Otherwise, you would first need to navigate to the folder that you want to create the new folder. You do this using the "cd /" to navigate to previouse directory and then to the one you want.
