+p "Hello World!"
+```
+
+2. What character is used to indicate comments in a ruby file?
+    - The pound symbol (#)
+
+3. Explain the difference between an integer and a float?
+    - A float uses decimals
+
+4. In the space below, create a variable `animal` that holds the string `"zebra"`
+```ruby
+animal = "zebra"
+```
+
+5. How would you print the string `"zebra"` using the variable that you created above?
+```ruby
+p animal
+```
+
+6. What is interpolation? Use interpolation to print a sentence using the variable `animal`.
+    - Interpolation is a way to process code inside of a string
+```ruby
+animal = "zebra"
+p "A #{animal} is often recognized for having black and white stripes."
+```
+
+7. What method is used to get input from a user?
+    - Input can be gotten using "gets" or if you want it in the same line you would use "gets.chomp"
+
+8. Name and describe two common string methods:
+    - One method is the ".split" method which breaks up string based on a specified criteria and returns an array. Another method is the ".sub" method which allows one to find and replace specific things within a string.
