The program below is an attempt to take in an American president, and French President's age, and name. The catch is that the French president says "bein sur" afterward calling his name, age and citizenship (not my idea). I'm having trouble with the French president's catchphrase. Here's my code

class President
  attr_accessor :name, :age

  def initialize(name, age)
     @name = name 
     @age = age
  end 

  def name=(name) # setter
   @name = name
  end

  def name # getter
   @name
  end

  def age=(age)
   @age = age
  end

  def age
   @age
  end
end

class FrancePresident < President
  def self.citizenship
    "La France"
  end 

  def initialize(name, age)
    super(name)
    super(age)
  end 

  def catchphrase
    "bein sur"
  end

end

class UnitedStatesPresident < President
  def self.citizenship
    "The Unites States of America"
  end
end

The instance method I have for his catch phrase is the last attempt out of many to get this guy to say this phrase, but it's incomplete, I think I'm supposed to define calls to the super class for getting his name and age, but I'm unsure of how to get past this argument error. 

ArgumentError
wrong number of arguments (1 for 2)
exercise.rb:4:in `initialize'

exercise.rb:32:in `initialize'

exercise_spec.rb:24:in `new'

exercise_spec.rb:24:in `block (3 levels) in <top (required)>'

I'm new to ruby, so any hints or suggestions will be greatly appreciated.

Replace this:

super(name)
super(age)

with this:

super(name, age)

The initialize method in President takes two parameters, not one.

You could even remove the arguments, and the parameters will be passed by default:

super

Better yet, just remove the entire initalize method in subclasses of President, because it is inherited.
