History of Latin America

What I need to do is analyze three primary sources from Chapter 5 of Latin American Voices (“The Perils  of Progress”) and answer the following question: What do these sources reveal  about the impact of the era of liberal reform and the notion of “Progress”  throughout Latin America? For context, make sure you’ve read Chapter 6 of Born in  Blood and Fire.   

I uploaded the book in pdf and also uploaded chapter 5
