Nice work on this @knestler . I can tell you have a solid understanding of Ruby syntax, datatypes, and conventions. Please see my comments and I would encourage you to adjust anything that should be fixed.

= is the assignment operator. You should be using a different operator here ==.
To prove this, try changing your has_sauce variable to "no", and then running line 70 again - it still returns true! Can you figure out why this is? Comment here!
| 5. What is the Ruby syntax for an if statement? | ||
|
|
||
| if variableX = 2 |

Again, do not use the assignment operator for if statements
| 7. Provide an example of the Ruby syntax for an if/elsif/else statement: | ||
|
|
||
| if variableX = 2 |
|
|

| # YOU DO: Write code that will reassign the last item in the animals | ||
| # array to "Gorilla" | ||
|
|
||
| animals[-1]= "Gorilla" |

| 8. What questions do you still have about hashes? | ||
| How often are hashes used? |

All the time!!! They are a very useful datatype because they allow a "lookup" that is FAST!
(aka, it's much faster to find something in a hash with 1 million key/value pairs than to find the same thing in an array with 1 million elements)
This is my mod 0 work!
