"When the economy is bad", is a way of referring to a negative situation economically, such as being left without a job, without economic income, due to bankruptcy of your own business, among others, that does not allow growth or economic stability. Therefore, when a community is in an economic crisis, people stop spending as much money on services and goods that are not as essential as leisure. Furthermore, companies no longer need the services of many of their workers because they cannot pay their wages. However, primary services such as health always receive income and that people continue to assisted hospitals, clinics, doctor's offices, and places where they can be assisted by medical personnel such as doctors, nurses, specialists, among others because it is a primary need. It cannot be radically suspended. Therefore, the correct respect is to D. A Nurse.
I am not sure if there is a mistake in the question?
The correct answer COULD BE Austria-Hungary, or in other times just "Austria" or "Austrian Empire". The capital of the empire was in Vienna and the most important unifying factor was the power of the Habsburgs: the Empire was composed of many ethnicities and many languages but what they had in common was the Habsburg rule.
Austria-Hungary included parts of today's Germany, Austria, Moravia, Bohemia, the Netherlands and parts of Italy, France, Poland, whole of Hungary. However, Denmark was not part of Austria- HUngary .
Another good candidate is the Holy Roman Empire. Here the whole of Switzerland was also included, as were Germany, Austria, Moravia, Bohemia, the Netherlands and parts of Italy, France, Poland, However, again, Denmark was not part of it and neither was Hungary.
So in the end, the question is confused and lists some mistakes in it.
I personally would go with Austria-Hungary, since the definition of this empire was more fluid, as in "all the lands that belong to the Habsburgs", but I feel that the question might be asking for the Holy Roman Empire (and mistakes Hungary as a part of Austria-Hungary to be a part of the Empire, which it wasn't).
