1. Explain what Booch means by "collections of subprograms" when describing 
   older programming approaches.

	Older languages supported procedures (methods), but not self-contained
	objects, so a large program would consist of a bunch of unrelated 
	procedures all thrown together.  Booch uses the term "subprograms" to
	mean procedures.
	

2. What are the "two major goals in developing object-based software" Booch quotes?

	- increasing programmer productivity and reducing maintenance costs
	
	- building systems that "resist both accidental and malicious 
	  corruption attempts"


3. Why are understandability and maintainability enhanced by OO, according to Booch?

	"objects and their related operations are localized"
