 1. What is an object?
+  In Ruby, everything you manipulate and the results of those manipulations is an object.
 
 2. What is a variable?
+  Variables keep track of objects by holding a referance to that object. They are the container in which values are stored.
 
 3. What is the difference between an object and a class?
+  In Ruby a class is a category of things that are represented in code. A class is a combination of state and methods. 
+  An object is everything you manipulate and the results of those manipulations.
+  So, objects are instances of classes which are themselves objects.
 
 4. What is a String?
+  A string is a sequence of charaters.
 
 5. What are three messages that I can send to a string object? Hint: think methods
+  There are more than a hundred methods in the String class. Three listed from the text are
+    String#split - break a line into fields
+    String#scan - convert time from mm:ss to seconds
+    String#chomp - removes newline character
 
 6. What are two ways of defining a String literal? Bonus: What is the difference between the two?
+  1 - with single quotes 'this is a string'
+  2 - with double quotes "this is a string"
+  difference - use double quotes for string interpolation (for when you want to imbed a variable in the string) and for greater character subsitution options.

 Sharing Functionality: Inheritance, Modules, and Mixins
 
 1. What is the difference between a Hash and an Array?
+  A Hash is an index of objects and an Array is an index of integers.
 
 2. When would you use an Array over a Hash and vice versa?
+  Use an Array when there is a given order to data stored and use a Hash when the name or key is more suited as order doesn't matter.
 
 3. What is a module? Enumerable is a built in Ruby module, what is it?
+  A module generally contains a collection of methods for use by other classes. In Ruby, Enumerable is a collection of classes with traversing and sorting methods and can sort. 
 
 4. Can you inherit more than one thing in Ruby? How could you get around this problem?
-
+  No you cannot, it is not allowed in Ruby. A Ruby object can have many ancesters and an object can include modules and subclasses to extend funcionality.
+
 5. What is the difference between a Module and a Class?
+  A class can produce an object and a Module cannot, a module is a collection of methods for use by many classes.

 1. What is a symbol?
+  A symbol is an identifier which cresponds to a string. It is preceded by a :.
 
 2. What is the difference between a symbol and a string?
+  A symbol is not mutable and is stored in the same object id... they are faster to work with than strings.
 
 3. What is a block and how do I call a block?
+  a block a chuck of code enclosed in curly braces or the keywords 'do' and 'end'. To call a block a block use an iterator. Common iterators are 'each', 'collect/map' and 'find'. (loc 2418 - inject interator from Enumerable... work through examples)
 
 4. How do I pass a block to a method? What is the method signature?
+  You pass a block to a method using 'yield' or by passing the last element in the method signature with an &. The method signature is the method name... the content of the line following 'def'.
 
 5. Where would you use regular expressions?
+  I use regular expressions when I want to find a pattern within a set of strings.
