Problem: European Central Bank:

The first President of the Bank was Wim Duisenberg, the former president of the Dutch central bank and the European Monetary Institute. While Duisenberg had been the head of the EMI (taking over from Alexandre Lamfalussy of Belgium) just before the ECB came into existence, the French government wanted Jean-Claude Trichet, former head of the French central bank, to be the ECB's first president. The French argued that since the ECB was to be located in Germany, its president should be French. This was opposed by the German, Dutch and Belgian governments who saw Duisenberg as a guarantor of a strong euro. Tensions were abated by a gentleman's agreement in which Duisenberg would stand down before the end of his mandate, to be replaced by Trichet.

What did the French, German, Dutch and Belgian governments finally compromise on with regards to managing the ECB?

A: Duisenberg would stand down before the end of his mandate, to be replaced by Trichet

Problem: Computer security:

Today, computer security comprises mainly "preventive" measures, like firewalls or an exit procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network, such as the Internet, and can be implemented as software running on the machine, hooking into the network stack (or, in the case of most UNIX-based operating systems such as Linux, built into the operating system kernel) to provide real time filtering and blocking. Another implementation is a so-called physical firewall which consists of a separate machine filtering network traffic. Firewalls are common amongst machines that are permanently connected to the Internet.

How are firewalls implemented?

A: unanswerable

Problem: Ashkenazi Jews:

In this respect, the counterpart of Ashkenazi is Sephardic, since most non-Ashkenazi Orthodox Jews follow Sephardic rabbinical authorities, whether or not they are ethnically Sephardic. By tradition, a Sephardic or Mizrahi woman who marries into an Orthodox or Haredi Ashkenazi Jewish family raises her children to be Ashkenazi Jews; conversely an Ashkenazi woman who marries a Sephardi or Mizrahi man is expected to take on Sephardic practice and the children inherit a Sephardic identity, though in practice many families compromise. A convert generally follows the practice of the beth din that converted him or her. With the integration of Jews from around the world in Israel, North America, and other places, the religious definition of an Ashkenazi Jew is blurring, especially outside Orthodox Judaism.

By tradition, when a Sephardic or Mizrahi woman marries into an Orthodox or Haredi Ashkenazi Jewish family she raises her children to be which type of Jew?
---
A: Ashkenazi Jews

Problem: New York City:
