When you have read the above articles:
Write a summary of what you have learned from the articles, what you agreed (or disagreed with) and so on.
You can talk about what you learned from the articles; what you liked; what you did not like; what the authors missed in their article; how the articles relate to your experience and so on. When I read your discussions I want to see evidence that you have actually read the material and that you truly understand what you read and how it applied to the real world business environment.
