6. What is the method that starts on line 23 doing and what is the output?

• The attribute of each name in the "non_devs" array is going to change to "true" and returns the non_devs array with the attribute changed to "true"
  En verdad modifica @cosumers, no "non_devs"

a = [ "a", "b", "c", "d" ]
a.collect {|x| x + "!" }

9. On line 37, how is @Consumers set?
   -It is a hash

10. For the method below the protected keyword, how might an instance of taco call this method (say in a controller, a view, or another module)?
    Como es protegido (y aplica igual para privado) se accede asi: taco.send(:is_really_good) would return true.
