 1. What is an object?
-
+An object holds information that methods can interavt with and manipulate. Everything in Ruby is an object.
 2. What is a variable?
+A variable is a place where information is stored that has a unique name identifier. They keep track of objects, and each variable is a reference to an object. 
 
 3. What is the difference between an object and a class?
+Classes are created and defined, and they are define the paramters of objects. Objects are anything you can interact with in Ruby. 
 
 4. What is a String?
+A string is a sequence of characters.
 
 5. What are three messages that I can send to a string object? Hint: think methods
+split, squeeze and chomp
 
 6. What are two ways of defining a String literal? Bonus: What is the difference between them?
+Single quotes and double quotes. The difference is the escape sequences you can use with each. Double quotes have more escape sequences available.

 Sharing Functionality: Inheritance, Modules, and Mixins
 
 1. What is the difference between a Hash and an Array?
+A hash stores a whole integer while an array can hold any object. 
 
 2. When would you use an Array over a Hash and vice versa?
+You would use a hash when you have a key and an object corresponding to that key, such as the key being "name" and the object being the person's name. 
 
 3. What is a module? Enumerable is a built in Ruby module, what is it?
+A module is simliar to a library, and it interacts with functions to perform repeatable processes. Enumerable allows you to terminate a loop cleanly when there are no additional values. 
 
 4. Can you inherit more than one thing in Ruby? How could you get around this problem?
+You cannot inherit more than one thing in Ruby, and you get around this with mixins. 
 
 5. What is the difference between a Module and a Class?
+Modules interact with functions while classes are about objects.
