Validation issue: Labs- Install [Q:4 and 5]

Seems like there is a validation issue for q4 and q5 of Labs- Install

Q4: Exit from ansible-controller-2 host and return back to ansible-controller-1 host.

Add localhost as a managed host in the default Ansible inventory file.
I have added localhost in default inventory file, but it is showing task not completed.

Q5:

It would be good if you can add solutions as well.

I see the log_path parameter in the config file is commented.
