It's always great that people share knowledge and the examples as well, but I just went through the first questions and most of them are not to be resolved with BR's at all. Assignment rules for assigning, dictionary entries/UI policies will make fields mandatory, change task templates assure copied values, etc.
If these questions are asked in a job interview and you would answer with 'let's use a BR', it will not land you the job.
Please mark any helpful or correct solutions as such. That helps others find their solutions.
