Question 14/20
Explanation: The HOME environment variable determines your working directory when you log on. This is
typically /home/<username> for a normal user account or the root directory (/) for the root user. The HOME
environment variable also determines the directory you will be taken to if you enter the 'cd'
command with no arguments.
