Debugging patterns (2)

Both patterns in this exercise contain mistakes and won't match as expected. Can you fix them?

The nlp and a doc have already been created for you. If you get stuck, try printing the tokens in the doc to see how the text will be split and adjust the pattern so that each dictionary represents one token.
