I want to know the answer to the following question:
In 2001, Portugal was the first country in the world to do what?
All the background I'm provided with is that "Portugal maintains a unitary semi-presidential republican form of government and is a developed country with an advanced economy, and a high living standard, having the 18th highest Social Progress in the world, putting it ahead of other Western European countries like France, Spain and Italy.". Is that enough to answer the question?
Answer: no
