This week's question: You are a mad scientist and have to steal a world monument to bring to your Hong Kong lair. What would you choose?

I'd bring America's Statue of Liberty and her intangible cultural values. She symbolises liberty and freedom, which echoes my own wish to chase after my dreams.
Lady Liberty is not standing still, but moving forward, which parallels my determination to progress in my science career. It is also a reminder for me to try to achieve greatness.
The tablet in her hand represents knowledge which I believe equals power. This increases my determination to become somebody and contribute to society.
And lastly, of course, I could pass on this spirit to everyone around me, impart knowledge to them, and make a real impact on society.

Tour de France winners pass L'Arc de Triomphe on the last stage of the race. This 'arch of triumph' would be an obvious choice for me, as it would symbolise my eventual victory in my plan to rule the world.
