This question is set up to asses your knowledge of the industry that you are applying for. This is why it is important to read up on contemporary issues before the interview. It might be a good idea to describe a policy that is linked to the industry that you are working in, e.g. if you are applying to work for network rail then you may wish to comment of the plans to build a high speed rail link between Melbourne and Sydney. There is no wrong answer as long as you can justify your ideas. Name drop the current transport secretary and any of his proposals if possible, but try not to take a strong political stance.
