 1. What character is used to indicate comments in a ruby file?
 
+   - it's called an octothorpe or pound character
+
 1. Explain the difference between an integer and a float?

+   - puts animal
+
 1. What is interpolation? Use interpolation to print a sentence using the variable `animal`.
 
+   - It's a method that allows you to embed/place Ruby code inside of a string by using the pound character with brackets `#{}` .(Assuming you mean string interpolation)
+
+   - ```Ruby

 1. What method is used to get input from a user?
 
+   - The `gets` method. The specific method we used earlier was `gets and chomp`

 1. Name and describe two common string methods:
