Explain Business Ethics

I'm looking for the answers to the questions in the above textbook on Page 573. They relate to the "Barrick Gold Corporation - Tanzania" Ivey Case. The questions are below:

1. What are the challenges faced by extractive mining corporations in their attempt to establish subsidiary operations in developing nations?

2. Why and how has Barrick Gold Corp. adopted a global approach to address corporate social responsibility issues in Tanzania?

3. Can tax revenues, rents, and subsidies be effectively utilized by Tanzania (and other developing nations with mining wealth) to generate prosperity in the densely populated area of the Lake Victoria Zone and to break the so-called "resource curse" that occurs in many poor nations? How?

4. Despite Barrick's efforts in the Lake Victoria Zone, protests and tensions had not abated by 2009. Why have the tensions and violence not stopped? What can the corporation do to eliminate such conditions?

If anyone has the answers to these questions, or can point me to a website that can help, it would be very much appreciated
