 Questions:
 1. What is method_missing and how can it be used?
+  It is automatically called when a method is called on a class where it isn't defined. The default is that it should then search the parent class to see if it's there (possibly tripping that method_missing). At the top of the tree, Object throws an error if method_missing is called.
+
 2. What is and Eigenclass and what is it used for? Where Do Singleton methods live?
+  An Eigenclass (or Singleton class) is an anonomous class that hosts the Singleton methods defined for a particular object. It is itself a child of the class that the object would be a child of.
+
 3. When would you use DuckTypeing? How would you use it to improve your code?
+  I can imagine having a method adding content to the end of a string, but it might be reusable to append an array. So long as my code is still readable, it is good to maintain less code.
+
 4. What is the difference between a class method and an instance method? What is the difference between instance_eval and class_eval?
+  The class method is applied for the entire collection of class objects, whereas an instance method is only applicable for a particular object.
+
 5. What is the difference between a singleton class and a singleton method?
+  A singleton method is defined on a particular object. A singleton class is the parent class created automatically to host the singleton methods of the particular object.
