Doubt in print_home_directory.sh regarding the question being asked in it

Actually, what I have to do in print_home_directory.sh. Question is not clear.

First you have to create 2 folders named backup and transfer
then copy vsftpd1.log to backup
and then print the final tree structure (using tree command)

All this have to be done using print_directory_structure.sh file, so write command to accomplish above changes in the file.
