Review

Finished this, but I don't understand why I needed instance variables to work through the scope in the last two problems.  The scope issues worked at the command line, but didn't within RSpec.  I expected that it was something I had to tweak in RSpec and thus would extend or include the class or something, but I couldn't find any info on that.  But then the instance variables worked, but I'm not sure why.  Please explain for me!
