What is wrong here?

It says I did not call the "run" method but I thought I did with the "def run" code I typed here.

simple_benchmarker.rb 
class SimpleBenchmarker
  def run(description, &block)
    start_time = Time.now
    block.call
    end_time = Time.now
    elapsed = end_time - start_time

    puts "\n#{description} results"
    puts "Elapsed time: #{elapsed} seconds"
  end
end

benchmarker = SimpleBenchmarker.new 
def run(description, &block)
  puts "This" do 
  end
end

#1of2 

benchmarker = SimpleBenchmarker.new

#2of2 

#first argument should have "string of description"
benchmarker.run "Any description you want" do

#second argument should have anything in block
  10.times do
    puts "any code you choose"
  end
end

What they wanted was for you to call the "run" method on the "benchmarker" object and pass it two arguments. Passing it two arguments meaning its still within the same calling of the object.
