Something is wrong with our self.included method and it isn't functioning correctly.

What is the answer to this question?

store.rb 
module Inventory
  def self.included()
    klass.extend ClassMethods
  end

  module ClassMethods
    def create
    end
  end

  def stock_count
    @stock_count ||= 0
  end
end

class Shirt
  include Inventory
  attr_accessor :attributes

  def initialize(attributes)
    @attributes = attributes
  end
end

you need to reference klass in the self.include method like so 

module Inventory
  def self.included(klass)
    klass.extend ClassMethods
  end

  module ClassMethods
    def create
    end
  end

  def stock_count
    @stock_count ||= 0
  end
end

class Shirt
  include Inventory
  attr_accessor :attributes

  def initialize(attributes)
    @attributes = attributes
  end
end
