def show
  puts %{We have two hashes:
@mismatched_animals: #{@mismatched_animals.inspect}
@matched_animals: #{@matched_animals.inspect}

Create a hash with properly matched key/pair values of animals and sounds:
#{expected.inspect}

Use the Hash method that will return a new hash with non-duplicate keys of
the first and second collectively. If the method uses a block it will
specify how to handle duplicate keys:
}
