Hi there!
When regions, places, monuments, or geographic features are discussed in politics, it is called geopolitics. Geopolitics mostly relate or is caused by global geographic features rather than by a smaller area.
Hope this helps!
I think the answer to your question you ask is the letter b. the second to last.
One problem for the social security system is that there's more and more older people and fewer young people, so if they massively retire, there won't be enough workers to keep the social security system working because not enough taxes will be paid. A possible solution can be an increase the the obligatory retirement age. This would mean that people would work longer before retiring so they would use less social security money.
