Huh.

Well cool.

ruby.rb 
def valid_command?("y", "yes", "Y", "YES")
  return true
end

Try this code:

def valid_command?(command)
  if command ==  "y" || "yes" || "Y" || "YES"
    return true
  end
end

You need to pass the method an argument (command) which will be evaluated within the method using an if statement and a series of 'Or' operators.

You could also scrap the logical operator completely here and make the function return false if the command is not valid.

def valid_command?(command)
  valid_commands = %w[y yes]
  valid_commands.include?(command.downcase)
end
