About the Ass5, I want you creat the 10 new works from your Ass1and Ass3. Pick 5 from Ass1 and pick another 5 from Ass3.
Then creat new works out of the 10 works. You can use all the 10 works and create the new works or you can use 3,4,5,6 to create your new works.
But you need to use all the 10 works in some of your new works.
