Personally I don't support that advice, but it's very much a matter of 
personal preference. I like each source file to declare its 
dependencies, because it lets them be re-used more easily, although it 
is easy to miss some.

I don't know why in your case you have to require set.rb before 
choice.rb. If you could boil choice.rb down to a small test case which 
demonstrates the problem, it should be fairly easy to identify. But 
without seeing the code, I'm only guessing.
