Commercial awareness – pot luck

Is there anything I should steer clear of when answering commercial awareness questions?

I know I need to demonstrate commercial awareness in application forms and interviews, but are there any issues I should steer clear of when answering questions. How controversial can I be? What if I mention a deal that hasn’t gone well? Should I stick to things happening in the legal market or more of a general current affairs issue? And what if things change between completing the application form and interview?

Any “safe” options?
