Supply and chain management

I have a Hw that is due from the Supply chain managment book. From chapter 1, 2, 3, and 4. Each chapter has a one qestion assingment assigned for us I have attached the sheet and questions posted by the professor. The professor want a one page about answer for each question. The Hw is due by 2:00 pm today. The hw is not very long but it needs alittle bit reading. The answers I think can be answerd from other sourcser than the book, but any source that is used from outside the book has to bee referenced correctly as the professor have really stricted referencing work and not copying any. Also if you have knowledge about the topic and searched from google also reference and change the wording to simple english, am an international student so the professor knows how the assingmet paper has to be in simple english as possible.
