+Bob answers 'Sure.' if you ask him a question.
+
+He answers 'Whoa, chill out!' if you yell at him.
+
+He says 'Fine. Be that way!' if you address him without actually saying
+anything.
+
+He answers 'Whatever.' to anything else.
+
+## Instructions
+
+Run the test file, and fix each of the errors in turn. When you get the
+first test to pass, go to the first pending or skipped test, and make
+that pass as well. When all of the tests are passing, feel free to
+submit.
+
+Remember that passing code is just the first step. The goal is to work
+towards a solution that is as readable and expressive as you can make
+it.
+
+Please make your solution as general as possible. Good code doesn't just
+pass the test suite, it works with any input that fits the
+specification.
+
+Have fun!
