On the Chef Style Guide page appears this Ruby expression: 

antarctica_hint = hint?('antarctica')

What exactly does the ? after hint and before ('antarctica') mean? Is it just part of the method name? (i.e. the method is called 'hint?' not 'hint')

It is part of method name, and people typically (not always) use it for methods that return boolean value.

An example from Ruby is Class#respond_to?
