Question

Before exiting Publisher, we should not close all the publications.

Answer 1

yes we should not close the publisher because publisher will exit

Answer 2

The statement is incorrect.  

Before exiting Publisher, we should properly save and close all the opened publications.

Exiting the software without saving it will cause consequences like the user cannot retrieve their earlier work.

So, whenever we use any programs, the files need to be saved before exiting it to view it for later use. Even it causes the shutdown process to be slowed down when we are not closing all the publications before exciting the publisher.
