Thanks for your question. The question mark separates the title from the subtitle.

Competition Law within the European Union Is Functioning Just Fine, but Do Fines Cut It? An Exploration of the Efficacy of Corporate Fines in Achieving the Goals of EU Competition Law, and the Potential Benefits of Reform.
